GOLDEN AGE EQ-73 Equalizer

The class-A circuit used in the EQ-73 is similar to the eq section in the classical 1073 module, without the high pass filter. Additional frequencies have been added and the mid frequency band uses two inductors, the higher value of the second one is used for the two lowest frequencies, 160 Hz and 240 Hz, to achieve a suitable response.

The sound character is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.

The EQ-73 has stepped frequency controls that offers a wide selection of frequencies from 20 Hz to 24 kHz.

The Low and High frequency bands are shelving and the mid frequency band is of the bell type.

The control range is +/-15 dB for the two lower bands and +/- 18dB for the high frequency band.

There are separate bypass switches for all three bands.

The EQ-73 is made to be used together with one of our PRE-73 models that has an Insert jack. It can also be used with many other units that has a low level insert jack.

Combining a PRE-73 and an EQ-73, and using a UNITE rack kit to mount them together, one will get a 19-inch 1073-style unit at a low cost and with a great sound!

DBX 2215 Dual 15-Band Graphic Equalizer with Noise Reduction

 It's amazing. One little button. So much effect. dbx? Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQs possible, boxes with the heritage and performance to rival our famous 30 Series EQs. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQs sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx; nobody... that's who. So when the guys were developing this new series of EQs they wanted something that would be unique to these EQs. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0dbu to plus 20dbu, the patent-pending PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQs. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQs at your pro audio outfitter. You'll see, with the 20 Series EQs you get MORE!!!

With 12 inputs and 6 outputs and Ethernet control the dbx ZonePro? 1260 and 1261
are the newest members of the ZonePro? family providing a complete suite of signal
processing and control for Commercial Audio applications.
Designed to offer superior system sonic performance and flexibility, the 1260/1261 deliver
the highest quality tools available. Even the input and outputs connectors were chosen for
their standard usage and reliability. The ZonePro products offer Euroblock connectors for
balanced signals and RCA connectors for interfacing with consumer equipment often used
in commercial applications; there is also a simple analog input buss that allows inputs to be
sent from one unit to the next for unit and job scalability. The 1260 and 1261 provide every
necessary processing tool, from the input processing like gain control and EQ available on all
inputs to highly sophisticated and specific functions such as selectable paging microphone
processing including Gating, De-Essing, Auto Gain Control, Compression and Feedback
Suppression. The heart of the ZonePro products is the Routing module that provides of course
Primary Source Selection but also Source Ducking for Paging and Priority Override. The outputs
also offer a wealth of processing designed for commercial applications like our patent-pending
AutoWarmth? function that was co-developed with JBL to provide natural low frequency extension
at any signal level. Each output also offers EQ, Bandpass and Crossover filters, Limiting and Delay
for system optimization. With the ZonePro? every tool is at your disposal to maximize the response
of your system.
Beyond processing, the ZonePro? products offer multiple forms of control to further extend the
versatility of your system. From easy-to-use wall panel Zone Controllers for standard end-user
functions like source select and volume control to advanced system control including a built-in
Real Time Clock that can provide programmable system changes throughout the day or week.
For system setup and monitoring the ZonePro Designer software provides an intuitive interface
and a speedy setup Wizard for configuring and editing all system parameters. The addition of
Ethernet control means that not only will it work with standard network equipment, but it can also
be accessed from remote dialup locations or from wireless access points.
The ZonePro? 1260 and 1261 will take your Commercial Audio system to the next level with advanced
processing, versatility and control.
