2.1.2. Stereo and M/S (Channels 1 and 2)
Via menu selection, channels 1 and 2 can be used as independent channels or
coupled for stereo or M/S operation.
When used as a couple of stereo or M/S channels:
Channel 1 fader is not used, but channel 2 fader becomes the master, controlling the
level of both channels.
The outer concentric control (of channel 2) provides +/-5dB adjustment of the
balance in L/R mode (normal stereo), or the stereo width in M/S mode.
In normal stereo mode
, the transducers usually have matching sensitivity;
x Any change of the input gain on one channel induces the same on the other
channel;
x The outer control on channel 2 controls the balance between L and R
channels ;
x Input 1 is routed to the Left bus, input 2 is routed to the Right bus ;
x Overriding this routing remains possible!
In “M/S” mode
, the transducers often have different sensitivity;
x The input gain adjustment is kept separate for channels 1 and 2 ;
x The outer control on channel 2 adjusts the stereo image width;
x In the center detent position, a coherent couple should provide a
normalised 110° angle;
x Whenever inverting the phase of channel 2, after decoding from M/S to
L/R the stereo image is reserved LlR.
x Manual routing is inhibited and the signals are routed and decoded as
follows:
Input 1 is the “M” signal, input 2 is the “S” signal;
Input1 + Input 2 (M+S) is routed to the Left bus;
Input1 - Input 2 (M-S) is routed to the Right bus.
