Features
High performance, value for money. High power ratings.
175W + 175W into 8 ohm (4ohm and 250W+ 250W). In bridged (mono) mode, 500W.
Designed to be:
Transported and reliable. Each amplifier is 3U high. It saves space in your rack.
Internal thermostatically-controlled 2 speed fans.
The fans eradicate the need for external cooling (more rack space saved) and allow continous high-power operation.
Balanced XLR and phone connectors
The two accept professional level signals.
The front panel contains decibeldetented attenuation controls
Such controls allow you to make accurate, repeatable level settings.
Signal and clip LEDs
Such give instant indication of signal levels.
Protection circuits
Protection circuits guard your equipment against short-circuits.
Yamaha's "soft-start"
The circuitry mutes the amplifier for a few seconds after power-on, safeguarding your speakers against damaging power on "thumps".
