You can wirelessly connect LEAK STEREO 130 to a music source via Bluetooth wireless technology. When the Bluetooth is not connected, the indicator light of the Bluetooth input flashes. After the Bluetooth is connected, the indicator LED glows steadily.Open Bluetooth search on your mobile phone or tablet and connect to “LEAK STEREO 130 BT”, if prompted to enter the password, enter “0000”. When the connection is successful, the music starts playing. Switch to another input during Bluetooth playback will disconnect after 1 minute. Switch back to the Bluetooth input for automatic connection.To disconnect the Bluetooth:• Move the Bluetooth source beyond the communication area.• Turn off the connected device or turn off its Bluetooth function.• Hold press the button of the remote control for 3 seconds to force the current Bluetooth connection to be disconnected.


Turn the bass adjusting knob on the front panel to increase (clockwise) or decrease (counterclockwise) the low-frequency response. Control range: -6db to +6dB.


Turn the treble adjusting knob on the front panel to increase (clockwise) or decrease (counterclockwise) the high-frequency response. Control  range: -6db to 6dB.Note:The RIAA playback characteristic has been incorporated in the LEAK STEREO 130, 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 (33 and 45 r.p.m) made prior to 1955, for instance, the bass and treble control may be used to correct differences in the recording characteristic. 1/3 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 bass boost which, if used at maximum, can only result in a travesty of the originalmusic. We have provided you with the 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 to low-intensity levels (as in an apartment late at night).


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 other channel will be silent.


Press the Direct button on the front panel of the LEAK STEREO 130 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 130 will bypass certain circuits within the amplifier design by stopping the power supply to these circuits. It will reduce noise and electronic interference (albeit minor) in order to reproduce the purest sound as is electronically possible.Note: bass, treble, and balance controls are not available when direct is activated.


LEAK STEREO 130 is protected by a thermal switch that 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.
