INSTALLATION NOTES

1. For normal usage and conditions the amplifier needs no supplementary heatsink.

2. It must be mounted to allow a vertical flow of air through the fins.

3. No input capacitor is required. An internal 100V working capacitor is fitted.

4. For loudspeaker protection it is recommended that a quickblow fuse is mounted

between the output and the speaker. The fuse rating specified has been calculated

to ensure fast rupture in the event of DC being presented to the speaker. It is

advised not to use a higher rated fuse.

5. The amplifier module is supplied in 8Ω mode. To set 4Ω mode simply break the link

using a spot face cutter or a 3-5mm drill.

6. For 4Ω mode use a 2.0A quickblow fuse and for 8Ω a 1.5A quickblow fuse.
