Setting up
For near-field or desktop use, space speakers apart for adequate stereo separation depending on
proximity to the listener. For installations using the supplied wall-mount brackets, attach the brackets
to a solid surface using fixings which are sufficient to hold the weight of the active speaker. Take
care to mount the active unit close enough to a mains outlet for the supplied adaptor to reach.
Fix the speaker units to the brackets at top and bottom using the supplied screw caps. Each can be
rotated to aim the general direction of sound output.
If the speakers are mounted at height or where falling objects may be hazardous, it is advised to
attach a secondary means of support (e.g. drop-wire or chain)
Operation
Link the powered speaker to the satellite using the supplied modular connector speaker lead (5)
With the rotary VOLUME (4) control set to minimum and TREBLE and BASS controls set to the
vertical (12 o’clock) position, connect the supplied mains lead to the rear of the active unit (2) and
plug into a suitable mains outlet. Connect the source signal into the active unit via either L+R RCA
connectors or 3.5mm stereo jack input (8, 9). Switch the power on (3) and gradually turn the rotary
VOLUME control clockwise and increase volume level to the required amount.
The stereo/mono switch (6) offers mono output for both speakers if required. Stereo is default.
Adjust TREBLE (7) and BASS (10) controls to provide the desired tonal response.
The centre position is unaffected, to the left is cut and to the right is boost.
Turn down rotary VOLUME control before switching off.
