8.0 PROTECTION FEATURES

TANNOY iwsa500-D

8.0 PROTECTION FEATURES

8.1 Limiter Function

The limiter function is included to prevent dangerous clipped signals reaching the speaker and damaging it. If an amplifier is severely overdriven, its output waveform is clipped (its peaks are squared off) - reducing the crest factor. In extreme cases the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its normal undistorted rated output power.

The Tannoy iwsa500-D Amplifier has two modes of thermal protection and an auto shut down when an internal fault is detected.

9.0 MAINTENANCE

Under normal use the amplifier should provide years of trouble-free service, with no maintenance required.

10.0 TROUBLESHOOTING

These are typical things to check if you think your amplifier is faulty:

FAULT: No power indicator light

Check for proper voltage at receptacle.

Make sure power cord is properly seated in connector on the rear of the amplifier.

Check power switch on back of amplifier.

Check fuse located in holder/drawer below power input connector on back of amp.

FAULT: No output

If the power indicator light is on, verify that there is a usable signal on the input.

Check position of level control knob on the front of the amplifier.

Check speaker cable connections on the output binding posts for bad connections.

Check speaker cables for possible short circuits.

FAULT: The amplifier does not respond even after having checked the above items.

In the unlikely event of a non-user rectifiable fault return the amplifier to your supplier, or an approved service center.

Tannoy cannot be held responsible for damage or injury as a result of the top or bottom cover being removed.
