5. Reverb Control
A hall reverb is available on Channel 1 and 2. Use the reverb control to mix in some additional am-
biance to your signal. This often works well with vocals.
Channel 3/4
1. Input
Min Max
Line level signals can be connected to either of the TRS phone jacks or the 1/8-inch stereo input
jack on Channel 3/4. The 1/4-inch jacks can accept either balanced or unbalanced signals. If only
one of the 1/4-inch jacks is used, the channel self configures for mono playback.
If a stereo source is connected but the EXM400 is setup in a mono configuration, the signal from
Channel 3/4 will automatically be summed to mono.
2. Level Control
The EXM400 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 adjust the chan-
nel's level in the overall system mix.
3. Tone Controls
Clip
Channel 3/4 is equipped with a pair of tone controls for enhancing the channel's signal. The treble
STEREO
Line 3/4
and bass controls allow for a +/- 6 dB adjustment at 2000 and 110 Hz respectively. When placed at
the center position, these controls are bypassed.

dom to play your music wirelessly.

You will see a device named "YS-####" where #### indicates a four digit number unique to your
EXM400. Select this device to initiate pairing. Once you see the "YS-####" device connected, you
will be able to stream audio to the EXM400.
2. Bluetooth™ Status Indicator
Min Max
The blue status indicator alerts the user to the current status of the Bluetooth™ connection. A fast
blinking light indicates an available, unpaired connection. Clusters of three short bursts mean there is
an active connection. No light means that Bluetooth™ is disabled or a connection has been lost.
3. Bluetooth™ Level Control
Use this control to set the audio level for the Bluetooth™ connection. Level can also be controlled
directly at your streaming device.
Limit
The EXM400'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 EXM400 and the streaming device.

Master Section

Min Max
1. Master Control
Use the Master Control to set the overall level of the EXM400. This control sets the output of both
the satellites and the subwoofer.
When two systems are linked together, the Master Control only affects the level of the unit it resides on.
Min Max
2. Sub Control
The sub control sets the relative level of the subwoofer to the satellite speakers. Typically, this
control should be set to noon.
If an additional pair of EXM400SAT speakers is being used, you may want to turn this control up.
If you are using microphones and acoustic guitars and do not need much bass, turn the Sub level
down to prevent low frequency feedback.
