SoundCraft D-Mix 500 - Manual (Page 27)

Input Stage
(1) The input switch selects the input source. When this switch is pressed INPUT A(B)
has been selected and the LED to the right of the switch lights up orange. When the
switch is released a green LED will illuminate thus meaning the
MIC 1(2) input source
has been selected.
(2) Gain- Adjusts the level of the selected input, and should be set up carefully to ensure
a good signal level to the rest of the mixer. If it is set too high the signal will distort as
it overloads the channel and causes clipping. If it is set too low the level of any
background hiss will be more noticeable and you may not be able to get enough signal
level to the output of the mixer.
(3) A mix of the outputs of channels 3 and 4 feeds the FX INSERT SEND jack on the
rear of the console. Here the signal may be run through any kind of processor and back
into the console via the FX INSERT RETURN jack socket. When the FX switch is
pressed, the signal from the RETURN jack is routed to the console Master section.
Make sure the channels you wish to send to FX are ON.
Equalisation
(4) The Equaliser (EQ) allows precise manipulation of the sound, particularly to
improve the sound of microphone sources where the original sound is often far from
ideal.
Three EQ bands are provided, HF (High Frequency), MF (Mid Frequency) and LF
(Low Frequency). These EQ bands provide 15dB of cut or boost at 10kHz, 2.5kHz and
160Hz respectively on the D-MIX500; 5dB cut and boost at these frequencies on the
D-MIX500L.
Channel Output
(5) The Peak LED warns the DJ of excessive signal level in the channel 6dB before
clipping occurs. The signal is sampled just after the EQ section, and illumination of the
LED will indicate that the input sensitivity is set too high, or that the EQ settings are
too extreme.
(6) The Channel ON switch enables and disables the channel. When the switch is set
to the on position a green LED will illuminate showing the channel is active.
(7) The CUE switch enables the pre-fade channel signal to be routed to the DJ’s
headphones and booth monitors if required.
(8) The Output signal level from the channel is set by the Fader.
THE OUTPUT OF THESE CHANNELS CANNOT BE ASSIGNED TO THE
CROSS FADER
