Model 235-24 Video/Audio Distribution Amplifer

General
Model 235-24 is a 24 output video/audio distribution amplifier, designed for reproduction systems. It's transparent characteristics
ensure the highest quality in reproduced products for both professional and consumer media. It has one level of NTSC/PAL
bandwidth video and two levels of baseband audio.

Features
* Video in/out connectors are BNC. Inputs are looped-thu, with a swichtable 75ohm termination.
* Audio inputs are selectable to balanced(+4dBm nominal input level, with terminal block) or unbalanced(-10dBv nominal input level,
   with a pair of RCA jacks looped-thru, Hi-Z) The balanced inputs have built-in switchable 600ohm termination. The audio
   inputs have 20dB head room (+24dBm max. for balanced input, +10dBv max. for unbalanced input).
* Audio outputs are RCA jacks, unbalanced, -10dBv nominal level with +16dBv maximum level. With it's low output impedance'
   it ensures transparency for any kind of source materials.
* Front panel-accessible screw driver adjustable center detent gain control for video and audio makes gain settings easy and
   minimizes possible tampering.
* Front panel test points provide easy metering measures.
