In addition to the new (installed in 1970) Collins Audio Console (Model 212G), shown in the rack to the right is an Ampex AG-440 tape machine, a Spotmaster Cartridge Tape Machine (playback only), and a Tapecaster Cartridge Tape machine that had both record and playback capabilities.
The equipment racks (3) left to right contain:
A: Spare amplifiers, a Gates Program Equalizer for use with incoming remote lines from Bell Telephone's Hilltop Central Office (they had several permanently maintained Class "D" short loops) and within the school building itself, a CBS FM Volumax, monitor speaker, and patching. Note the polished patch cords hanging on side of rack.
B: A CBS Audimax III, a CBS Dynamic Presence Equalizer (DPE), an auxiliary VU meter panel, a VU meter for measuring gain reduction, an RCA Beat Frequency Oscillator Type 68-B, and RCA Noise and Distortion Measuring Equipment Type 68-C, and RCA Attenuator Panel plus additional amplifiers.
C: Off air monitor receiver, an EBS receiver, another VU meter with various functions to be monitored, patching, additional amplifiers, pads, power supplies, etc.
