Classé expands the Sigma series with a mono amplifier-- the Sigma MONO, an amplifier rated at 350W into 8 ohms and 700W into 4 ohms with proprietary amplifier design within a high performance package.

A special pass-thru feature allows the forwarding of input signals into a second amp for either bi-amplifying or driving of a subwoofer amp.

Such a feature allows installers to locate amps closer to each speaker, since a single long interconnect can connect the preamp to the first amp, followed by a short interconnect to the second Sigma MONO, or even a third and a fourth.

The Sigma Mono is available from October 2015.
