Features

• Compact -two fully independent channels in a single 3% inch rack mount chassis.

• 3-Speed Equalization accommodates any combination of NAB or IEC curves. LF equalization easily defeated at any speed.

• Full Remote Control of all modes: READY/RECORD; INPUT, TAPE and SYNC monitor. Solid-State switching eliminates contact noise.

• Distortion Reduced through the use of " Ilinearized" Recording Amplifiers and phase corrected Reproduce and Sync Amplifiers.

• Separate Reproduce and Sync Amp'lifiers permit optimum adjustment of equalization in both playback modes.

• Plug-In Circuit Cards combine advantages of both IC and discrete circuitry for unexcelled performance and trouble-free operation.
