MASTER LEFT/RIGHT FADER
The MAIN MIX LEFT/RIGHT fader [8] is a stereo fader located at the far right of the console. The fader controls the level of the main L/R mix bus, with precise dB markings and a unity gain point marked on the panel. This fader, like the bus faders, is located in the circuit after the bus insert jack but before the final line amplifier.

TAPE RETURN
The SR24�4 provides easy monitoring of your stereo tape recorder, whether you are using it in a studio mixing situation, you�re recording a live gig while you do the SR mix, or if you just want to play a little music through the system between sets. The TAPE RETURN knob [10] just to the left of the meters adjusts the level of the tape playback. The TAPE RETURN TO PHONES/C-R [11] button next to the PHONES/C-R LEVEL routes the tape playback

signal into the monitor system and meters. This allows you to listen to the playback signal off tape and to check the playback levels on the SR24�4 meters, even while you are recording. The TAPE RETURN TO MAIN MIX switch [12] next to the MAIN MIX fader actually routes the tape playback signal into the main Left/Right mix circuits, before the bus insert jacks and the master fader. VERY IMPORTANT! This switch also disconnects everything else coming up the L / R buses from the master fader and outputs. So, when you push TAPE RETURN TO MAIN MIX you get only the tape playback out the main L/R buses. This feature is designed as a quick and easy way to play a tape on the main speakers in a live SR application. ALSO VERY IMPORTANT! If your recorder allows monitoring of its input, assigning the tape return to master could cause a VERY nasty feedback loop. Be sure that your tape machine is not in Record, Record-Ready or Input mode. Handy Trick: If you have nothing plugged into the TAPE IN jacks, or have the TAPE RETURN TO control fully down, you can use the TAPE RETURN TO MAIN MIX as an oddly-named MAIN MIX MUTE switch!
