Troubleshooting
Avoiding Problems with Turntables
Since the SP-8S can produce a considerable output level at low frequencies,
acoustic feedback via a turntable can occur. To ensure that this is not the case,
perform the following test at installation of the SP-8S.
Set up the equipment for playing a record. Place the stylus on a non-rotating
record (disconnect the turntable power cord if necessary). Tap the turntable while
gradually increasing the volume of your audio system. If you begin to hear a
sustaining sound quality before you are able to advance the volume control to a
setting representing loud listening, acoustic feedback is a problem. You may need
to move either the turntable or the SP-8S to remedy this problem. Alternately, try
placing an anti-vibration pad under the turntable.
Replacing the Fuse
The SP-8S is protected from power anomalies by a fuse. In the event that the
SP-8S does not seem to have power even though connected to AC, check the
condition of the fuse in the fuse holder (#11). If the fuse needs replacing, it is
critical to use only a fuse with an identical rating.
