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.

Controls and Functions

MONO INPUT CHANNEL SECTION - continued

PEAK LED

The XM910’s MIC/LINE pre-amp also includes a PEAK LED which, when illuminated, indicates that the signal is peaking or overloading. To reduce distortion, lower the GAIN control to keep this LED from staying on.

GAIN - Control

The XM910’s pre-amp stage has a variable GAIN control with a range of -6 to

-50dB on the MIC input and +14 to -30dB on the LINE input.

VOLUME - Level Control

The VOLUME control adjusts the output volume of each channel.

STEREO INPUT CHANNEL SECTION

The XM910 features two stereo input strips, which include channels 7/8 and 9/10. While these channels look very much like the mono channels, they have two inputs so they can accept a stereo signal. The AUX send and Equalizer are laid out on the same as the mono inputs on the control panel, but internally, they are controlling a stereo signal path. As an added bonus, these inputs also include a microphone input, which can be used in mono. There are two differences in the stereo channel controls, the Balance control and Gain. These controls are detailed in the following section.

BALANCE (Stereo Inputs Only)

The MDR1064’s BALANCE control is used to place or position the stereo signal into the main Left and Right MIX bus. You can move a stereo signal’s image to the left or right by setting the BALANCE control to the left or to the right.

GAIN - Control (Stereo Inputs Only)

The XM910’s pre-amp stage has a variable GAIN control with a range of -6 to

-50dB on the MIC input and +14 to -30dB on the LINE input.

VOLUME - Level Control

The VOLUME control adjusts the output volume of each channel.
