Stereo Linking
The Stereo Link feature allows two pairs of 552 inputs to be linked as stereo pairs. These are inputs
1,2 and inputs 3,4. In the Setup Menu inputs can be linked as either a Stereo Pair or an MS Stereo
Pair. Input Linking is indicated by the odd channel’s (1 and 3) LINK LED. When an input pair is
linked as an MS pair, both the Link and MS LEDs will be lit.
Stereo Pair Linking
When Stereo Linking, input channels 1 and 2 and/or channels 3 and 4 act as a single stereo pair, con-
trolled by the odd channel’s Fader. The odd channel’s Pan control acts as the balance control between
left and right. The even channel’s Fader and Pan controls are not active when inputs are linked. The
Trim control and High-Pass Filters continue to act independently of each other. When linked, the
channel’s Input Limiters are also linked. When inputs are linked as a stereo pair the odd input’s Link
LED is illuminated.
MS Pair Linking
When Linking inputs as an MS pair, channels 1 and 2 and/or channels 3 and 4 are linked as an MS
pair. The odd input (1 and 3) is the Mid signal and the even input (2 and 4) is the Side signal. The
odd channel’s Pan Control functions as a left/right balance control for the matrixed MS signal. The
even channel’s Fader and Pan controls are disabled. Each channel’s Trim control and high-pass filter
continue to act independently of each other. Use channels 1 and 2’s Trim controls to vary the Mid
and Side levels respectively. When linked, the Input Limiters are also linked. When inputs are linked
as an MS pair the odd input’s Link and MS LEDs will illuminate blue.
Input Muting
Any input can be removed from the mix so that its signal is not sent to the master left and right out-
puts. An input that is removed from the mix in this way is still present in the direct output and the
isolated input selections for AES A source. See AES Digital Outputs fr details.
1) Press in on the headphone controller 2) Press the input’s PFL.
