SUM100-RCA

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 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. 

Front panel, screwdriver adjust, full range gain controls provide 28dB gain at full clockwise rotation, unity gain at twelve o’clock and a smooth audio taper to full off. The output driver is a servo controlled, ground-sensing circuit, which will supply over +24dBm to 600 ohm balanced loads and +20dBu to high impedance, unbalanced loads. The SUM100 uses rugged XLR type input and output connectors. 

Loop-through DC connectors allow several NANOAMPS to share a single external 24VDC power supply. Battery packs and DC-DC converters for portable use are also available. Up to three amplifiers will mount side-by-side in only one 19-inch rack unit using the available rack mounting kits. NANOAMPS may also be neatly stacked or mounted side by- side on your desk with the available angled desk mounting kits.
