Channel 1 is equipped with a combi-jack optimized
for a microphone (XLR) or a balanced line level
(1/4-inch) source. A level control sets the gain and
relative volume while the clip LED indicates the on-
set of clipping distortion. For powering condenser
microphones, 24V of phantom power is present on
the XLR input portion of the jack.
Channel 2
Channel 2 is equipped with a combi-jack optimized
for a microphone (XLR) or an instrument level
source (1/4-inch) source. A level control sets the
gain and relative volume while the clip LED indi-
cates the onset of clipping distortion. For powering
condenser microphones, 24V of phantom power is
present on the XLR input portion of the jack.
Channel 3
Channel 3 is equipped with an XLR jack optimized for a microphone (XLR), an unbalanced TRS 1/8-
inch phone jack optimized for portable media players and Bluetooth™. A level control sets the gain
and relative volume while the clip LED indicates the onset of clipping distortion. For powering con-
denser microphones, 24V of phantom power is present on the XLR input portion of the jack.
Note: When Bluetooth™ is used the volume is controlled by Channel 3’s Level control.
Bluetooth™
The Yorkville EXM Mobile/Mobile12 is capable of receiving streaming audio over Bluetooth™ from
devices such as smart phones, tablets and laptops. Pairing your device with the EXM Mobile/Mo-
bile12 is simple and gives you the freedom to play your music wirelessly.
Pairing:
When the Enable Button is depressed for 4 seconds and then released, the Bluetooth™
audio connection is available for pairing.
Status:
The blue status indicator alerts the user to the current status of the Bluetooth™ con-
nection. A fast blinking light indicates an available, unpaired connection. A slow blinking blue
light is pairing mode waiting to pair, and a steady (solid) blue light is paired and audio is
available to Channel 3.
Level Control:
The Channel 3 Level control is used to set the audio level for the Bluetooth™
connection. Level may also be controlled directly at your streaming device.
The EXM Mobile/Mobile12’s Bluetooth™ operating range is rated for 10 meters (33 feet) line of
sight. The quality of the link can be affected by an excess of traffic in the 2.4 GHz bandwidth or
structures between the EXM Mobile/Mobile12 and the streaming device.
Note: When connected with Bluetooth™, ALL audio is streamed from your device. If you don't
want your streaming music to be interrupted, turn off 'notifications' on your device.
Channel Controls
Level Control
The EXM Mobile/Mobile12 features active channel input circuitry with exceptionally high audio
headroom. The Level control adjusts the channel gain over an 85 dB range. Use this control to ad-
just the channel’s level in the overall system mix.
Shape Control
Setting this control towards ‘Music’ shapes the response to be suited for reproducing prerecorded
music while setting the control towards ‘Speech’ accentuates the mid-frequencies which help
speech and vocals. The response is flat in the center position.
Effects Control
This control determines how much of the selected effect (see “Effect Selector” in the “Master Sec-
tion” portion of this manual) is applied to the corresponding channel.
