DATA SHEET
HY2003 60 WATTS
The ILP HY2003 Power Amplifier is a fully
encapsulated high quality power amplifier
with Integral Power Supply and heatsink.
By selecting the appropiate mains transformer and the programming link on the
PCB the amplifier can be used with 4 or 8Ω loads with the automatic adjustment
of input sensitivity.
Mounting can be achieved by the use of T-slots in the heatsink and the nuts and
bolts provided.
• FEATURES

POWER SUPPLY REQUIREMENTS
ILP have developed a range of Hi-Fi quality Low noise Audio Power Toroidal
Transformers for the HY2003 they are Low Profile with Resin filled centres for
maximum noise absorption and ease of mounting. Finished in black to match the
amplifiers these transformers are the ideal choice to power the HY2003.

INSTALLATION NOTES
1. For normal us age and conditions the amplifier needs no supplementary heats ink.
2. It must be mounted to allow a vertical flow of air through the fins.
3. No input capacitor is r equired. An internal 100V working capacitor is fitted.
4. For loudspeaker protection i t is recommended t hat a quickblow fuse is mounted
between the output and the speaker. The fuse rating s pecified has been cal culated
to ensure fas t rupture i n t he event of DC being presented t o t he speaker. It is
advised not to use a higher rated fuse.
5. The amplifier module is supplied in 4Ω mode. To set 8Ω mode si mply make a link
between the two pads marked 'link'.
6. For 4Ω mode use a 2.5A quickblow fuse and for 8 Ω a 2.0A quickbl ow fuse.
