accept line levels signals from as low as – 2 0dBu to a high +10dBu. The level is matched to
the console using the front panel GAIN A control. The signal can be mixed with Input B if
required by pressing both A and B ON switches together. An optional RIAA card may be
fitted internally for direct connection to a magnetic turntable cartridge. Refer to your
