User manual BIAMP EQ 210-110

[. . . ] To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. Remote Control: Remote level control is available as a user installed option. [. . . ] Remote control capability is added by installing VCA Cards onto the mixer circuit board (see diagram on next page). CAUTION: Turn off and/or dis-connect AC power before performing any modifications. To install VCA Cards, first remove the jumper wires (between OUT and IN) on the respective channels/outputs of the mixer circuit board. Then install the two plastic support/guides (provided with each VCA Card) into the holes provided on the respective channels/outputs of the mixer circuit board (support/guides must be properly oriented to accept VCA Card). A combination of potentiometer and switch may be used, with the switch in line with either the "C" or "+10V" connection. NOTE: When a VCA Card is installed, but no control is connected, signal will not pass. To avoid this circumstance, a jumper wire may be temporarily connected between "+10V" and "C". Additionally, if VCA Cards are removed, jumper wires must be reinstalled between OUT and IN on the respective channels/outputs of the mixer circuit board, before signal can pass.
