Signal Levels

It is important to supply the correct input levels to the console, otherwise signal to noise ratio or distortion performance may be degraded; and in extreme cases, damage to the internal circuitry may result. Likewise, on all balanced inputs avoid sources with large common-mode DC, AC or RF voltages, as these will reduce the available signal range on the inputs. Note that 0dBu=0.775V RMS.

The microphone inputs are designed for use with balanced low impedance (150 or 200 ohms) microphones.

The Phones output is a 3-pole "A" gauge jack, suitable for high or low impedance headphones (8ohms - 2kohms).

Caution!

Do not use unbalanced microphones or battery powered condenser microphones without isolating the +48V phantom power: degraded performance or damage to the microphone may result.

The sensitivity of the Mic inputs is variable from -15dBu to -50dBu, with a maximum input level of +4dBu. The Mono Line Input sensitivity is variable from -20dBu to +15dBu with a maximum input level of +30dBu.

The Stereo Input is provided with a gain trim of +/-10dB, with a maximum input level of +32dBu for CD or AV inputs. Vinyl inputs are suitable for moving magnet cartridges.

The main outputs of the mixer (Left/Right) are balanced at a nominal level of +4dBu. Maximum output level is +26dBu into 5kohms.
