Niles Audio SI-1650 manual Listening AT Higher Volumes, Cleaning and Maintenance

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS

OPERATION

LISTENING AT HIGHER VOLUMES

Fifty watts is enough power to play a conventional speaker in a normal sized room loudly enough to completely drown out conversation. Even at levels like that, the SI-1650 will sound clear and clean. However, it requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion.

Clipping distortion makes treble sound very harsh and unmusical. When you hear harsh sounding treble from any good speaker, turn the volume down immediately! Those harsh sounds are masking some much more powerful high frequency sound spikes which will quickly damage the tweeter of any loudspeaker.

If you continue to operate the amplifier at “clipping” power levels the protection circuits will operate when the amplifier overheats. The protection circuits reset when the amplifier’s internal circuitry cools. Reduce the volume to prevent a reoccurrence. Perpetually overdriving your speakers and amplifier is abuse and probably voids the manufacturer’s warranty of all affected products.

CLEANING AND MAINTENANCE

The internal parts of the SI-1650 are electronic and require no maintenance. Once a year it is appropriate to twist the RCA connectors on each input to remove any oxidation and improve conductivity.

You can clean only with dry cloth. Do not use any spray-type, abrasive cleaners on the amplifier.
