PLAYING MUSIC VIA BLUETOOTH
You can wirelessly connect the LEAK STEREO 230 to a music source via Bluetooth wireless technology. When the Bluetooth device (smartphone, tablet or PC
etc) is not connected, the indicator light of the Bluetooth input will flash. When a Bluetooth devices is connected, the indicator LED will be illuminated.
To connect a Bluetooth device, access the Bluetooth connectivity menu on your your Bluetooth device (smartphone, tablet or PC etc) and connect to
'LEAK STEREO 230 BT'. If prompted to enter the password, enter '0000'.
Bluetooth will disconnect after 1 minute, if you switch to another input from Bluetooth playback. Your device will automatically reconnect to the LEAK STEREO
230 when you switch back to the Bluetooth input (assuming the device is within range).
To disconnect the Bluetooth:
• Hold press the button on the remote control for 3 seconds to force the current Bluetooth connection to be disconnected.
• Bluetooth with automatically disconnect if you remove the Bluetooth source beyond the communication area or turn off the connected device or turn off its
Bluetooth function.
BASS
You can adjust the bass output by adjusting thr BASS knob on the front panel. To increase, turn clockwise. To decrease, turn counterclockwise. The BASS
control range is -6db to +6dB.
TREBLE
You can adjust the treble output by adjusting the TREBLE knob on the front panel. To increase, turn clockwise. To decrease, turn counterclockwise. The TREBLE
control range is -6db to +6dB.
Note:
The RIAA 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-back characteristic is of use only as an approximation, and it 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 (331/3 and 45
r.p.m) made prior to 1955, for instance, the bass and treble controls maybe used to correct differences in the recording characteristic.
When playing European 78 recrods, the ‘TREBLE’ control should, theoretically, be turned to ‘2 O’Clock’.
Consumer opinion in some countries insists on a magnitude of available bass boost which, if used at maximum, can only result in a travesty of the original
music. We have provided you with an availability of 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, though an intermediate setting may be helpful,
particularly when listening at low intensity levels (as in an apartment late at night).
BALANCE
The balance knob on the front panel can adjust the sound output balance of the left and right 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 the LEAK STEREO 230 to activate the direct function, and the indicator above the key will light up. Click to turn
off Direct again and the indicator goes off.
The LEAK STEREO 230 will bypass certain circuits within the amplifier design by stopping the power supply to these circuitts. It will reduce noise and electronic
interference (albeit minor) in order reproduce the purest sound as is electronically possible.
Note: bass, treble, and balance controls are not available when direct is activated.
PROTECTION MODE
The LEAK STEREO 230 is protected by a thermal switch which interrupts the AC Power supply if the amplifier is grossly overloaded for a period of time. To
restore operation, simply press the Standby button on the front panel. It is thus fully protected against gross overload, short-circuited output etc, but not
necessarily against seriously inadequate ventilation.
