ASHLY 2.24 GS TWO CHANNEL GRAPHIC EQUALIZER-SYSTEM PROCESSOR

The 2.24GS allows for the installation of multiple channel graphic equalizers where
tamperproof, sound shaping equalization is required. Control and programming of
the 2.24GS is easily achieved from the 4.24G Main Unit, 4.24RD Remote Control,
through the use of Ashly's exclusive Protea System Software running on a PC, or by
a MIDI controller. The Protea 2.24GS is housed in an all-steel, 1RU chassis, and has
two independent channels of fully programmable 28-band graphic EQ with with limiter,
high- and low-pass filter, and time delay functions.
Each channel allows for 28 bands of 1/3-octave, ISO centered, constant Q filters,
ranging from 31Hz to 16kHz. High and low pass filters are 24dB/octave adjustable from
20Hz to 10.6kHz and 33Hz to 20kHz, respectively. Time delay is adjustable up to 1.364
seconds.
Other features include 24-bit A/D-D/A conversion, 24-bit/100MHz digital processing,
RS-232, and MIDI interface, linkable channels, +6dB/-infinity master gain, and 128 preset
locations. The 2.24GS displays individual channel numbers with 7-segment displays.
Discrete LEDs indicate signal present and signal clip levels. Rear-panel connections include
balanced XLR and 1/4" ins/outs for each channel, RS-232, MIDI In, Out/Thru, and Ashly's
exclusive digital remote control protocol via two standard XLR connectors.

Phonic's GEQ3102F is the authentic soundman's choice of EQ - a dual channel 31-band equalizer, offering 6 or 12 dB of cut or boost on standard ISO center frequencies between 20 Hz and 20 KHz. The GEQ3102F is 2-rack space units high and accepts both 1/4" TRS phone jacks and XLR connectors, making it ideal for any studio or live venue setup.

• Sweepable high and low cut filters on each channel to remove unwanted frequencies 
• Ultra low-noise audio operational amplifiers offer outstanding sound performance

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!

1215 Dual 15-Band Graphic Equalizer

The dbx 12 Series were designed to meet the needs of the most
demanding sound reinforcement environments, while offering the
simplicity of straightforward controls. The 1215 provides standard
features like dual channels, 15 2/3 octave bands, ISO frequency
centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters, but also includes other thoughtful features.
These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut
range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS
connectors for installation ease; balanced inputs and outputs for quiet
operation; and chassis/signal ground lift capabilities for quick hum isolation.
The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years
of maintenance-free operation in any application. The magnetically isolated
transformer, electronically balanced/unbalanced inputs and servo balanced/
unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire
relay bypass with 2 second power up delay were steps our engineers took
to ensure compatibility for all installations. Only the best components were
utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR
(ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail
is contained in a 2U steel/aluminum chassis.

•   Switchable boost/cut ranges of ±6 or ±15 dB
•   Electronically balanced/unbalanced inputs
•   Servo balanced/unbalanced inputs
•   RF filtered inputs and outputs
•  XLR, Barrier Strip, and 1/4" TRS connectors
•  -12dB/+12dB input gain range
•  18dB/octave 40Hz Bessel low-cut filter
•  Chassis/signal ground lift capability
•  Internal power supply transformer
•  Power-off hardwire relay bypass with 2-second power-up delay

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!!!
