The digital audio inputs of the RM-4C8 cannot in themselves clip unless extra input gain
has been applied, but signal peaks may come within 0.5dB of maximum if the input
signal has undergone aggressive processing at an earlier stage, and the CLIP indicator will
respond to this.
LOCK L and LOCK R indicators
The LOCK indicators illuminate when a valid digital audio signal is present on the
corresponding currently selected Source input. They will not illuminate if the currently
selected Source input is an analogue signal, or if a digital audio signal is applied which has
a sample rate outside the acceptable range of the unit, contains invalid/non-audio data or
is too weak for the receiver to lock on to.
Audio Modiers
The audio modiers are controlled using the 6 white
illuminated buttons on the front panel. Each of the
modiers is operated via an illuminated pushbutton
switch, with each press of the button toggling the
modier from on to o or vice-versa.
When using the audio modiers in combination, it
is necessary to consider the order in which they are
applied since that will aect the results.
The modiers are applied in the following order
(rst > last):
Phase invert > Mono > S+D > Dim > Cut L/R
When mains power is removed, the status of the audio modiers is stored in non-volatile
memory and recalled instantly once power is restored.
DIM Audio Modier
When on, the button is illuminated and the loudspeaker volume level is reduced by 10dB.
The DIM modier may also be activated by an external signal applied to the rear panel
remote control port. The DIM button will illuminate when such an external signal is active.
CUT L & CUT R Audio Modiers
When on, the button is illuminated and the corresponding loudspeaker channel is muted.
The CUT L and CUT R modiers may also be simultaneously activated by an external signal
applied to the rear panel remote control port. Both CUT buttons will illuminate when such
an external signal is active.
The CUT modiers will aect the loudspeaker audio, line-level audio outputs and phase
meter reading.
MONO Audio Modier
When on, the button is illuminated and the two currently selected audio Source signals are
summed into a monophonic signal prior to further processing and reproduction. Scaling is
