EXM
EXM
Primary unit (left channel). Both EXM ProSUB units will automatically attempt to re-establish the
Stereo Mode connection the next time they are powered on and enabled, with the same Primary
and Secondary roles previously used.
You can still pair new devices to an EXM ProSUB Primary unit if it is in Stereo Mode. Pairing a
device to an EXM ProSUB that is in Secondary mode will end the stereo wireless connection.
Button Operation
Single Tap – Enables Bluetooth™
Double Tap – Enter Stereo Mode
Press and Hold (4 seconds) – Enter Pairing Mode
Press and Hold (8 seconds) – Disables Bluetooth™
Range
The EXM’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
Bluetooth™ unit 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
Input Jacks
The input jacks on the EXM ProSUB can be fed with mono or stereo from your source. It is best that the
audio source go directly to the EXM ProSUB and then looped to your full range loudspeakers through the
High Pass Output jacks, this ensures there’s an ideal crossover to the full-range loudspeaker.
For mono signals, the Left or Right jack will accept a ¼-inch or XLR cable. When using stereo
signals, the EXM ProSUB’s mono output will sum the Left and Right signals internally.
Note: stereo separation is maintained for signals leaving the High Pass Output jacks.
Sub Level Control
The EXM ProSUB Sub Level control sets the amount of bass added to the sound system by the
EXM ProSUB. This adjusts for the relative sensitivity of the companion full-range speakers and
the desired system frequency response. This control is best set by listening while operating at a
moderate level (i.e. before the onset of limiting) and then not changing it.
A setting of 0 dB on the EXM ProSUB Sub Level control is the best starting point when setting
up a sound system. From there, adjustments can be made to achieve the best sound.
Note: The 0 dB mark refers to the setting that will give full power when the line input is used and
the input signal is at a level of 0 dBV (1 Vrms).
High Pass Output Jacks
The High Pass Output jacks are provided to eliminate the need for an external crossover, use
these jacks to feed the input of your powered full-range loudspeakers. The output signal of these
XLR jacks has had the audio below 100 Hz removed, helping to achieve a flat system response
when feeding the full-range loudspeakers.
Full Range Output Jack
The Full Range Output jack can be used to send the full range source signal (mono/summed) to
additional EXM ProSUBs or other powered enclosures that do not require a stereo source.
Protection and Indicators
The EXM ProSUB has circuitry to help prevent amplifier clipping, over excursion and to
protect the amplifier and/or voice coil from overheating. At high levels the internal limiter
will limit the gain of the EXM ProSUB. This is to ensure the desired low frequency balance
prior to limiting.
Battery Status Indicators
The EXM Mobile/Mobile12 has a series of four LEDs to indicate the approximate charge
level. The upper green LED is illuminated if there is greater than 75% charge in the
battery. The red LED only will indicate that the battery is critically low (approximately
10% remaining) and needs immediate charging.
The indicators will be engaged only when the power switch is turned on.
