This combination is under the control of the mixer operator in the monitoring room, viewing the set through a double window in the studio wall. The mixer controls also the gain of the amplifiers for the recording machines. AMPLIFIER ROOM NEQUAUZER »B" PRE I RECORDING ROOM FERABLY A CONSTANT: IMPEDANCE EQUALIZER MONITOR ROOM I Fig. 4.
