Left / Right Channel and Mono Selection
The SPK-24GX Wireless Speaker System comes with one speaker and is designed for either Mono
or Stereo playback. For stereo playback, an additional SPK-24GX speaker must be purchased
separately. Mono playback is suggested when each speaker is used in a separate area or room. The
transmitter supports up to a total of 6 speakers in stereo or mono modes.
Mono Playback
To enable Mono playback, ensure that the switch located on the back panel of the speaker is in the
MONO position.
Stereo Playback (ONLY applies with optional purchase of additional SPK-24GX
speaker).
To enable Stereo playback, set the switch on one of the two speakers' back panel to LEFT. Set the
switch on the other speaker to RIGHT.
Note 1: It is also possible to listen to only the Left or Right audio channel using only ONE speaker
To do so, simply set the switch on the speaker's back panel to LEFT or RIGHT.
Only the channel selected will be audible.
Note 2: If two speakers are connected to the system, ensure both speakers are placed within the
effective operational range. If either speaker is out of range it will cause distortion to
both speakers.
AUX In
To connect an audio device directly to the speaker insert a 3.5mm audio cable (not included) from
the source device into the „AUX In‟ jack located on the back panel of the speaker. This feature
sends audio directly to the connected speaker. It does not send an audio signal to any additional
speakers. Set the volume on the audio source device 75% of maximum.
Note:
If the source signal is too weak for reception, the speaker automatically switches off after
approximately 4 minutes to protect the unit and save power. If the source signal returns to an
adequate level, the speaker automatically switches back on.
When the speaker is in Standby mode, the speaker automatically switches off after
approximately 15 minutes to protect the unit and save power.
To switch speaker power back on during Standby mode, press the POWER button on the remote
control. The signal link between the transmitter and speaker reconnects automatically.

Ensure that the audio device volume level is set 75% of maximum.
Distortion
Speaker batteries may be too weak. Replace with new batteries or connect with the included AC
adapter. Blinking BLUE light on transmitter indicates drained batteries.
Ensure that the audio device volume level is set 75% of maximum.
The speakers are too far from the transmitter. Move closer to the transmitter base.
The audio input signal may be too low or too high. Set the audio source to 75% of maximum.
If using multiple speakers ensure all speakers are placed within the effective operational range.
If any speaker is out of range it will cause distortion on all speakers.
