This is a compact four-channel buffer/mixer/distribution amplifier. Any of the four inputs can be assigned to any (or all) of the four outputs. Two independent mixing buses enable signals to be mixed before or after the gain stages. Front panel controls provide ±15 dB of gain adjustment that may be assigned to the inputs or outputs, and the outputs can deliver +24 dBm to a 600 ohm or higher impedance load. Jumper blocks are used to configure the unit, thus affording complete flexibility with security; nobody can casually re-configure your system by twiddling the knobs.
