Cable Choice
Always use the best quality of cable available within your budget. High quality audio signals passing from the amplifier to the loudspeaker are unusual in their demands on the cable. Wide dynamic range and frequency bandwidth information has to coexist with the ability to transmit peak currents of at least 10 amps, without incurring any loss or signal impairment. This explains why the sound quality of the information reproduced by the loudspeakers is so dependant on the physical properties of the cables connecting them to the amplifier.
Terminal Panel
In order to take advantage of the driver earthing feature within Glenair 10 and to optimise performance further, use a shielded or screened loudspeaker cable. The screening termination should be connected to the earth or 'ground' (green) terminal on the loudspeaker and to the ground or earth connection on the amplifier.
Alternatively if you are not using a screened loudspeaker cable but wish to utilise the earthing facility, run a single cable between the earth or 'ground' (green) terminal on the loudspeaker to the earth (ground) connection on the amplifier.

Connecting your Loudspeakers
To avoid potential damage to your loudspeaker, ensure that the amplifier is switched OFF prior to connecting or disconnecting any cables. Before switching on double check that all connections are secure and that polarity is correct.

•Without removing the link plates on the terminal panel, start with the red (positive) lead. Fit this into the red (positive) high frequency (HF) terminal on the loudspeaker. To do this, loosen the terminal nut sufficiently to allow insertion of the cable and then
•The cable at the other end of the lead should be connected to the red (positive) terminal on the amplifier.
•Repeat this operation for the black (negative) HF terminal, and connect to the black (negative) terminal on the amplifier.
•Repeat the whole operation for the other loudspeaker.
Choosing the HF terminals for single wire mode has been found to give the best sound quality.
Select a signal source, such as a CD player; switch on the amplifier and slowly turn up the volume control to check that both loudspeakers are reproducing bass and treble information.
