Signal Levels
D-MIX500 Installation
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.
