Allen & Heath 23 XB-14 MK2 User Guide
STEREO INPUT CHANNELS ST3 & 4
USB RTN (ST6) level
The source for the ST6 input is from the USB audio device, in other
words from an external computer. The level control varies the gain ap-
plied to the USB audio device input signal from off (fully attenuated) to
+15dB.
SIMILAR TO THE ST1 & 2 CHANNELS—
THE DIFFERENCES ARE DETAILED HERE.
CRM SPEAKERS outputs
Standard RCA phono sockets for connecting to either powered speakers
or a stereo amplifier for the control room speakers. The output level can
be controlled by the CRM Speakers Level control.
Nominal level = 0dBu, unbalanced.
USB audio send & return
The USB connection uses a USB1.1 compliant stereo USB audio CODEC
which is also fully compliant with USB 2.
The connector is a standard USB “B Type” connector.
When connected to a computer (Windows or Mac) you will be able to
transfer stereo audio to and from the XB-14.
The signal source for the send is selected using the switches below the
USB connector.
If all switches are un-pressed, the post-fader main program mix will be
sent to the USB output. The priority switch matrix also gives the choice
of post level MIX B, post level audition bus and AUX (left hand channel)
and mono program feed (right hand channel).
The USB audio input can be selected to feed the stereo channel 4 (ST4)
by selecting the stereo input 6 (ST6) to that channel.
