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 satellite speaker to the spring terminals on the powered speaker (5) using the supplied speaker lead (connecting red to red and black to black)

With the rotary VOLUME (3) control set to minimum and TREBLE and BASS controls (1, 2) set to the vertical (12 o'clock) position, connect the attached mains lead (7) to a suitable mains outlet. Connect the source signal into the active unit via the L+R RCA connectors (4). Switch the power on (6) and gradually turn the rotary VOLUME control clockwise and increase volume level to the required amount.

Adjust TREBLE (2) and BASS (1) 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 the rotary VOLUME control before switching off.
