Note·

The RIM playback characteristic has been incorporated in the LEAK STEREO 230, as this is the internationally agreed standard. This characteristic does not take into account the acoustics of the recording studio, the position of the microphones relative to the artists, your pickup, your loudspeaker systems, the acoustics of your room, and your particular ears! In other words, the play-bock characteristic is of use only as an approximation, and ii may well be necessary to adjust the final result by using the controls marked as ‘BASS’ and ‘TREBLE’; this is the reason for their presence. When playing LP records 133 113 and 45 r p.m) made prior to 1955, for instance, the bass and treble controls may be used to correct differences in the recording choracteristic.
When playing European 78 records, the ‘TREBLE’ control should, theoretically, be turned to ‘2 O’Clock’.
Consumer opinion in some countries insists on a magnitude of available boss boost which, if used at maximum, can only result in o travesty of the original music. We have provided you with on availability of a bass boost which you certainly should not need if your pickup and loudspeakers are moderately good. It is not possible to obtain true bass from small loudspeaker systems by turning the ‘BASS’; control to maximum, !hough on the intermediate setting may be helpful, particularly when listening at low-intensity levels in an apartment late at night).

BALANCE
The balance knob on the front panel can adjust the sound output balance of the left and righ1 speakers to compensate for an unbalanced sound.
Note: if you turn the balance control knob to full Left or Right, the opposite channel will be silent.

DIRECT

Press the Direct button on the front panel of lhe LEAK STEREO 230 to activate the direct function, and the indicator above the key will light up. Click ta turn off Direct again and the indicator goes off.
The LEAK STEREO 230 will bypass certain circuits within the amplifier design by slopping the power supply lo these circuits. It will reduce noise and electronic interference (albeit minor) in order to reproduce lhe purest sound as is electronically possible.
Note: boss, treble, and balance controls ore not available when direct is activated.

PROTECTION MODE
The LEAK STEREO 230 is protected by o thermal switch which interrupts the AC Power supply if the amplifier is grossly overlooked for a period of time. To restore operation, simply press the Standby button on the front panel II is thus fully protected against gross overload, shorl-circuited output etc, but not necessarily against seriously inadequate ventilation.
