For Sale- Tested and working professional stereo EQ. Made in Japan.
One owner studio piece. Works 100%. Faceplate, controls, sliders are in mint or near mint shape, top of case has some minor cosmetic wear from being rack mounted.
Controls and Features
The Q2031A offers a full 6 or 12dB cut or boost at any of 31 points, which are centered at ISO (International Standards Organization) 1/3 octave frequencies from 20hz to 20kHz. Each channel features 31 separate active filters. Each filter has a positive detent in the center "flat response" position.
Range Switches
Each channel features a range switch so that the boost and cut range of the filters can be reduced from the normal +/-12dB to +/-6dB.
Input and Output Capabilities
Each channel features balanced, low-impedance XLR type connector inputs and outputs, as well as unbalanced high-impedance 1/4" phone jack connectors. Should input transformer isolation be desired, two octal sockets are provided on the back panel for insertion of 15 k to 15 k ohm bridging type transformers. Both channels have slider level controls. The EQ IN/Out switches have green LED indicators that let you know when the EQ is On.
Continuously Variable HPFs
High Pass Filters are provided on both equalizer channels. They provide 12dB per octave rolloff below the desired frequency adjustable from 20Hz to 200Hz. A green LED indicates that the high pass filter is in use.
Safety Devices
Independent peak indicators (red LEDs) are provided for each channel. The automatic muting circuit remains muted for approximately 3 to 5 seconds after the power is switched On, preventing transients from damaging amplifiers and speaker systems.
