The 160XT also works well on vocals at lower ratios (between 2:1 and 4:1) with gain reduction just on peaks. Features. The balanced input also appears on a ¼-inch TRS jack, and the unbalanced output driver circuit from the 160VU and 160X remains in place on a separate ¼-inch jack. The DBX 160 was first released as a single rack space unit in the mid 1980s as far as I can remember and it has remained pretty much unchanged since. As was most often the case in that 1960s audio era, Blackmer’s interest as an engineer and circuit designer focused largely on maximizing the dynamic range of recorded media. DBX 160X - Works especially well on drums & bass (low frequency stuff) DBX 160XT - Shines a little more on vox DBX 160a - More sterile and sightly less flattering, but covers more sources equally. Regarded by some as … So deliberate was his focus that Blackmer, in 1971, named his company after his goal of deciBel expansion: dbx. Read honest and unbiased product reviews from our users. If you have never heard the original dbx 160, I feel sorry for you. During the process of designing noise reduction systems for tape recorders (dbx’s first, and often overlooked, products), Blackmer, in 1971, developed the core of what would ultimately be his greatest legacy, the Blackmer Gain Cell: four transistors—two NPN, two PNP—arranged as complementary current mirrors, one pair able to alter the current flow through the other upon receipt of an incoming control current. Outputs, like those on the 165, are unbalanced and ground-canceling. dbx also manufactured a pair of high-end compressor/limiters, the 160S/SL and 162S/SL. Extremely useful analo “The 160x/xt is fantastic. First, and most obviously, the form factor changed to a full-width single-rackspace with LED input and gain reduction meters. Photo: Mark Ewing. The key to maximizing the performance of these VCAs lay in the painstaking process of matching individual transistors to one another, and thermally coupling them to ensure consistent performance: a transistor’s transfer characteristics can change depending on the component’s temperature. It’s uncanny at first – the gain reduction needle moves but there’s no “audible” compression. As is often the case with audio devices that have earned “classic” status, these shortcomings weren’t necessarily a bad thing and often contribute to their desirability. The Waves dbx 160 plug-in does exactly the same. By default, the 160X employs the same ground-canceling, single-ended output circuit as the 160 VU. Classic 1U mono dbx compressor with "that" sound. Description. The 160 VU makes kicks and snares pop, and even the most inconsistent of bass tracks sit in a mix with consistency. The dbx® 160A is a legendary dbx® 160 family of compressor/limiters. The Americans call the 160XT a “color compressor”. The ease of use makes it quick and easy to get a good sound and the bypass button is handy when A/Bing your signal. Update my browser now, The dbx 160 Compressor, Its Variants and a Little Bit of VCA History, By Mix Edit Another persistent myth about the 160VU is that it has balanced I/O. download 1 file . All iterations of the dbx 160, including the 161, the 160X, the 160XT, the 160A, the 162 and the 165, used electronically balanced or unbalanced inputs and outputs built around operational amplifiers. DBX 160A Review The DBX 160A compressor is a very simple to use compressor that has been around for a very long time. Another interesting option: the AB1 electronically balanced output card featured a fully balanced output with an op-amp stage driving both hot and cold leads, which show up on the terminal strip; still no XLR connectors! As mentioned earlier, this is untrue: the 160X did not ship standard with an output transformer. Up for sale as I am moving away from a rack set-up. Dynamics of the LED displays are excellent and it’s easy to see what the compressor is doing, even from a distance and under poor lighting conditions First, where the core of the 160 VU was the 200 VCA and 207 RMS detector, the 162 used the 210 VCA, a four-transistor device (a pair of complementary current mirrors; the true “core” of the Black gain cell) on a daughter card instead of the expected potted can. Stereo linking works very well and takes just one jack lead. dbx 160XT Compressor/Limiter Instruction manual. I have a pair of 166's and a 166xl (and 160xt FWIW) but have not used the 266, so can't compare there. The dbx 160 VU model used the first commercial version of the Blackmer gain cell, the 200 VCA, and its companion RMS detector, the 207/208. Visit our corporate site. The terminal strip is also gone, replaced with proper XLR connectors with one important caveat: the XT was “pin 3 hot” from the factory. DBX 160XT Compressor Limiter Tested and Fully Functional used FedEx DHL F/S. In 1989, the dbx division of BSR was acquired by Edison Laser Player, a Japanese company whose founder, Sanju Chiba, invented the laser turntable. It was also during this period that the 160x and 160XT were released. So what are the real differences between the 160 and 161 VU models? You should buy one whatever happens” The biggest difference between the 160X and 160XT lies under the hood, but a glance at the rear panel reveals all. Both the 200 and 202 VCAs—in fact, all but one Blackmer gain cell, the 2001—are class A/B devices that require careful trimming to minimize crossover distortion. Meanwhile, in 1980, audio engineer Paul Buff of Allison Research (which eventually merged with Valley Audio in Nashville to become Valley People) developed his own eight-transistor device, the class A TA-101, which formed the core of Valley People products like the famed Kepex, Gain Brain and Dynamite. Be the first one to write a review. Finally, the optional transformer footprint remains. The first commercial appearance of this circuit was the 202 “black can” VCA at the heart of the 165. dbx 160A Compressor Limiter. It is this principle upon which all of the later open-frame Blackmer VCAs are based. This allows for some pretty extreme compression effects During this period the dbx brand name was found on numerous consumer audio devices, including turntables, tape decks and amplifiers. This was the first unit to feature visual LED feedback for amount of gain reduction applied to source signal. In fact, the 161’s post-VCA current-to-voltage conversion op-amp stage is serving double duty as the output driver. The 165 adds attack and release controls, a threshold control with proper dB units and, most significantly, was the first dbx device to feature Over Easy soft-knee compression. David Blackmer received his training in electronics first from the Navy and later from both Harvard and MIT. The 160XT is deceptively simple with just three controls: threshold, compression ratio and output gain. The Blackmer gain cell was patented in 1973. This currently available descendant of the original 160 differs very little from its immediate predecessor, with the important exception of XLR pin configuration: the 160A is “pin 2 hot.” The only other apparent difference is a smaller, redesigned PCB layout, though that is a recent change; older 160As used a larger PCB similar to that of the XT. It should be added that none of the knobs is notched .. The 160XT is probably the best-known of the classic dbx 160 compressors. Interestingly, both outputs can be used simultaneously to drive different loads, as each output driver is independent of the other. Threshold and output level are self-explanatory. dbx 160には年代によっていくつかのバリエーションがあり、プラグインでモデリングされているのは70年代〜のモデルで、その後165A、160X、160XTそして現行の160Aと続いていきます。RECだけでなく、PA現場でもよく見かけるコンプですね。 There have appeared, on numerous internet forums, claims that the 160X includes a transformer-balanced output. Both inputs and outputs remain on terminal strips. See reviews for other specifications. Where a fully balanced output will produce the “hot” output signal on XLR pin 2 and an inverted or anti-phase signal (“cold”) on XLR pin 3, the 160 VU’s ground-canceling output is a single output op-amp stage with push-pull drive transistors driving pin 2, with pin 3 designed to cancel out any errant voltages, i.e., ground hum, that might appear on pin 1 (ground). This shopping feature will continue to load items when the Enter key is pressed. The name Dbx is pretty much synonymous with dynamic control in one form or another, and one of the latest products to emerge is the 162SL dual-channel compressor/limiter — a derivative of the flagship 160SL unit (reviewed in 160S form in SOS January … Get easy metering and tight control of threshold, ratio, and output, with selectable knee. JT-123-DBX, is still available from Jensen Transformers. After the classic 160 (which is still used daily in many world class studios), came the 165, the 160X and the 160XT. DBX 160XT Brand: DBX. The XT was the first 160 to ship with a fully balanced output, essentially the 160X’s optional AB1 card installed from the factory. comment. This brought the transistor count up to eight. Don’t be fooled by the price. The threshold control is still labeled in Volts, though the author has seen two versions of the front panel: an older version retains the 160 VU’s 10mV to 3V threshold labeling, while a newer version omits the unit altogerther and is simply labeled “.01” to “3.”, Also released in 1978, the 165 was clearly intended to be the flagship dynamics device in the dbx professional audio lineup. The 160XT is also superb for bass guitars and synths – it’s one of my favourites for bass guitar as it sits the bass just where you want it without killing the dynamics The original 160 was a half-width 2U box and the 160X was the first of the familiar 1U dbx rack compressors. Find helpful customer reviews and review ratings for dbx 160A Professional Audio Compressor/Limiter Dynamic Processor at Amazon.com. The good news for interested parties is that, at least on the 160A PCBs the author has seen, the transformer footprint remains. This four-transistor design ultimately formed the basis of every iteration of the Blackmer gain cell, including the seven-transistor 200 “silver can” VCA—the first to market—used in the 160 and 161 compressors. There is also a mysterious unpopulated header on the motherboard similar to those upon which the VCAs and RMS detector are mounted. Reverb is a marketplace bringing together a wide-spanning community to buy, sell, and discuss all things music gear. You might end up using an EQ after the compressor as well - or you can eq the sidechain separately by using the detector input The XT was the first 160 to ship with a fully balanced output, essentially the 160X’s optional AB1 card installed from the factory. The much smaller form factor, along with the current in/current out nature of the Blackmer VCA, enabled designers to cost-effectively use multiple VCAs in parallel. The most significant change, however, was the addition of dbx’s “overeasy” soft-knee circuit which premiered in the 165. Owners of some vintage VCA-automated Harrison consoles (Harrison, incidentally, also being located in Nashville) will find an ECG-101 on each of their faders. The first monolithic integrated circuit version of the Blackmer gain cell, the dbx 2150, was released in 1981 in the now-familiar 8-pin SIP package. Add to Compare (MAIL-IN MODIFICATION SERVICE): DBX "160X," "160XT," "160A" MONO COMPRESSOR. Created in collaboration with dbx®, this plugin is an authentic modeling of the vintage dbx 160 compressor / limiter, with new exclusive features … The front panel has an Over Easy switch, to change the shape of the threshold knee, meter input / output switch, bypass switch and a slave switch for stereo linking. The original dbx 160 VU is by now considered enough of a studio classic to both command steep prices on the vintage market and remain worthy of continuous production (albeit in modified form) since its release in 1976. The 146732 is equivalent to the dbx 2152/THAT Corp. 2159. Recall that the LP vinyl record of the time had a rather restricted—read: compressed—dynamic range in the neighborhood of 60 – 70 dB. At this time a number of critical patents were sold to THAT Corp (THAT is an acronym formed by the surnames of Les Tyler, Gary Hebert and Paul Traveline), whose 218x ICs—direct descendants of the original Blackmer gain cell—are still in use by companies like Solid State Logic, Smart Research, and various other manufacturers of VCA compression devices. It’s not a transparent, invisible compressor, but more like a giant hand that grabs hold of the signal to bend & twist it. It’d be interesting to chain it with a more subtle compressor for the best of both approaches, or use the 160XT for parallel compression The professional products division was then sold to AKG, which was in turn purchased by Harman International in 1994. All of the 160-derived devices are also feed-forward designs, wherein the control voltage driving the VCA into gain reduction is derived from the input signal and “fed forward” to the VCA, rather than being “fed backward” from the signal after it has already passed through the VCA. The output signal appears on a ¼-inch TRS jack as well as a terminal strip, a la the 160 VU. Inputs are balanced differential amplifiers. In a telephone conversation with David Kulka of Burbank, California’s Studio Electronics, Kulka pointed out that this header resides between the input buffer and RMS detectors, suggesting some manner of optional sidechain insert functionality. 590 Views . We don't know when or if this item will be back in stock. The next iteration of the dbx 160, the 160X, differs from the 160 VU in several significant ways. I see the XL as being mostly the feature add-ons and flexibility. dbx 160XT: First, see this article for an explanation of dbx's product-numbering system. Ease of use. Second, this is the first 160 to use the now-familiar 8-pin SIP integrated circuit VCA and RMS detectors, the 146732 and 146742, respectively. This is important to note, as designers of compressors and limiters based on other topologies at the time, like JFETs, diode bridges, electro-optical cells and the variable-µ vacuum tube, were limited by the transfer curve (which was often decidedly nonlinear in nature) of the gain reduction cell itself. Some other models like the old 160XT have fuller-sounding low end, just due to their response to big peaks. It is also important to note that the 160s compression curve was a “hard knee” curve: the onset of compression was instantaneous and often resulted in noticeable compression depending on ratio and threshold settings. Free shipping. Further, in a VCA application, four of the transistors are connected as diodes, which aids in maintaining audio waveform symmetry without the need for careful external trimming. $319.00.
