Architect's and Engineer's Specifications
The active equaliser shall be a 1 (or 2) channel rack-mountable unit with 15 (or 31) 'high definition' filters per channel placed on ISO centres.
Equaliser settings shall be graphically displayed by the position of each filter's centre-detented high-resolution control fader. A fader range switch shall be provided to allow selection of either 6dB or 12dB of band gain or attenuation relative to unity gain.
Inputs and outputs shall be via XLR and 1/4" jack connectors and shall be electronically balanced.
The equaliser shall have a unity gain frequency response of +0/-0.5dB from 20Hz to 20kHz, distortion of no more than 0.01% @ +4dBu, and hum and noise of at least -100dBu unweighted.
The equaliser shall be capable of delivering +22dBu (12V rms) into a 600 Ohm load. Equalisation and operational functions shall include 30-step detented rotary controls for: trimming output gain between -infinity and +6dB, a user-definable peak indication threshold control ranging from -10dB to +22dB, and a 24dB per octave high pass filter with corner frequency continuously variable between 5Hz and 200Hz.
The equaliser shall incorporate a facility to bypass the graphic filter section but not the high pass filter. A rear-mounted panel switch shall be provided to safely isolate signal grounds from AC and chassis grounds.
The equaliser shall be capable of operation from a 220/240V 50Hz AC power source, and shall be 2 rack units (3.5") high. A perspex front panel security cover shall be available.
The published specifications shall be met or exceeded.
The equaliser shall be a model EQ 152/311/312 manufactured by C Audio, Herts, England.

HIGH PERFORMANCE STEREO AMPLIFIER Features
Rugged steel chassis and a high standard of internal
construction ensure long term reliability in “real-world” operation. ■ Compact 2U (3.5”) height and very efficient forced
cooling make for economical and safe of high-density multiples. ■ Overall sonic quality
and satiability into long cable runs and
difficult loads enhanced by audiophile
grade circuit Topologies. ■ High CMRR electronically balanced inputs to both XLR and
0.25” jack Connectors, output on Neutrik Speakon Connectors. ■ Product reliability and service life extended through
optimum power supply design and
improved output stage efficiency. ■ In-built protection of amplifier and speaker loads against
faults and misuse ■ Ground lift switch fitted to help eliminate system hum
loops. ■ Large-scale use of common
assemblies and components simplifies
servicing and minimises spare parts inventories.

ACCURACY PERFORMANCE & POWER
RA Series design is the result of many years
In
particular the benefits of reliability, consistent stability into
“difficult” loads and the protection of the It is these features. together with the three models high level of commonality and their carefully graded power output ratings that have made RA Series amplifiers the choice of audio engineering professionals worldwide.
