LEVEL

(PEAK

and OVERLOAD

INDICATOR)

These

peak indicators provide visual indication of

the left and right output levels. They cover a range

of 0.002W to 400W (89) (—50dB to 3dB).

Note:

Also

that the meters are calibrated accu-

rately for output power into standard 2

speakers,

but

that

corrections

must

applied

if speakers with

different imped-

ance are used.

Clipping

(at about 2% THD)

is indicated for the

left and

right outputs

separately by the OVER-

LOAD

indicators. When these light up, turn down

the input level by using the LEVEL

controls on

the rear panel.
