Controls and Functions
MONO INPUT CHANNEL SECTION
The following section details each part of the XM910’s INPUT CHANNELS including
the 3-BAND EQ, the MONITOR and EFX sends, PAN, GAIN and VOLUME controls.
AUX 1/MON - Monitor Send
Each of the XM910’s channels include a MONITOR send which controls the
amount of that channel’s signal that is sent to the MONITOR bus. The Input
channel’s MONITOR sends are mixed together and are sent to the speakers
connected to the POWER AMP 1 A/B jacks if the POWER AMP select switch is
set to MAIN+MONITOR.
AUX 2 / EFX Effects Send
The XM910 provides high quality, 24 Bit digital effects, and the level of effects
can be set independently on each channel. The channel’s EFX (Effects) knob
controls the amount of signal that is sent to the EFX bus. The signal of the EFX
bus is routed to the DSP EFX section for on-board signal processing. The EFX
signal can also be sent to an external effect device connected to the AUX 2
SEND jack located on the front panel.
NOTE: The channel’s EFX signal is sent to the EFX bus from a location in the
signal path after the VOLUME control (7). This is commonly referred as a POST
FADER send. This means that the amount of signal that is sent to the EFFECT
bus will be affected not only by the setting of the EFX knob control, but it will
also be affected by the setting of the VOLUME control.
HIGH MID LOW - Channel Equalizer
The XM910 input channels feature a 3-band equalizer allowing you to adjust the
high, mid, and low frequencies independently on each channel. The channel’s
frequency response is flat when the knobs are in the "12:00" position. Rotating
the knob towards the right will boost the corresponding frequency band by
12dB/15dB, and rotating it towards the left will cut the frequency by 12dB/15dB.
The frequency centers, range of boost or cut, and equalizer type for each band
are as follows:
High: 12KHz +/- 15dB shelving type
Mid: 2.5KHz +/- 12dB peaking type
Low: 80Hz +/- 15dB shelving type
PAN - Control
The XM910’s PAN control is used to place or position the mono signal into the stereo main Left and Right
MIX bus. You can create a stereo image by panning some input signals to the left and others to the right.
The XM910’s PAN control is a Power-Pan circuit, which includes a 3dB dip in the center position. This is
desirable since there’s a 3dB increase in gain when the mono input signal is heard in both the Left and
Right MIX bus.
