Protection Circuitry
The protection circuitry may have operated if either of the follow-
ing conditions is noticed:
¢ No sound is heard when the power is switched ON.
(The current drive indicator of the operation indicator is not
illuminated.)
¢ Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for
example, the positive and negative speaker connection wires are
“shorted”, if speaker systems with an impedance less than the
106 dB (IHF ’66: 115 dB)

Notes:
1. Specifications are subject to change without notice.
Weight and dimensions are approximate.
2. Total harmonic distortion is measured by the digital spectrum
analyzer.
indicated rated impedance of this unit are used, or if DC
voltage appears in the output. _
If this occurs, follow the procedure outlined below:
1. Switch OFF the power.
2. Determine the cause of the problem and correct it.
3. Switch ON the power once again.
Note:
When the protection circuitry functions, the unit will not operate
unless the power is first switched OFF and then ON again.
