minimize sonic loss but also have immu- nity to induced noise, especially for instal- lations using long cable lengths..Balan- ced connections have 6dB more gain than single-ended connections. When level matching is critical, keep this speci- fication in mind. WARNING Use only one set of inputs to the amplifier at a time. -
