A high signal-to-noise ratio is important in signal construction and combination. The HA-5147 aids in lowering overall system noise and thereby raises system sensitivity. The signal combination circuit incorporates input bufferiug with several other features to form a relatively efficient mixer stage with a minimum of cham1el crosstalk. The potentiometer used for each channel allows for both variable input levels and a constant impedance for the driving source.

The buffers serve mainly to prevent reverse crosstalk back through the resistor network. This buffering allows for the combination of varying strength signals without reverse contamination. The gain of the final stage is set at a minimum of 10 and can be adjusted to as much as ZO. This allows a great amount of flexibility when combining a vast array of input signals.
