The SUM100 Summing Amplifier is an inexpensive, high performance amplifier that is designed as a line level stereo-to-mono summing amplifier. It is also useful as a gain block, and as an impedance converter and summing amplifier for IHF (RCA type) signals. The inputs provide balanced 40Kohm bridging impedance for line levels up to +24dBm. The high input impedance allows the SUM100 inputs to also bridge -10dBu (hi-fi, RCA plug) lines without loading.
