Sound Leisure MK8 Amplifier Supplement Manual
£15.00
Official Sound Leisure MK8 amplifier supplement for engineers, covering wiring, inputs, microphone control, slave outputs, jumpers, and zone configuration.
Full Product Description
This official Sound Leisure supplement manual provides detailed technical documentation for the MK8 mono sound amplifier, used in a range of Sound Leisure jukebox and audio systems.
The MK8 amplifier is a two zone mono system built around the SLD1009 pre amplifier top board. This document is intended for engineers and service technicians and should be used alongside the main system or mechanism service manual. It focuses on amplifier configuration, wiring, signal routing, and diagnostic reference rather than end user operation.
The manual includes clear board layout diagrams showing connector locations, jumper positions, potentiometer controls, and status LEDs. Detailed pinout information is provided for all inputs, including Jukebox, Auxiliary, Microphone, and Slave connections, with explanations of signal priority, earth references, and voltage behaviour. The microphone input is documented in depth, covering fade control, mute functions for Zone 1 and Zone 2, balanced and unbalanced microphone wiring, and karaoke style overlay operation.
Sections explain the operation of the two status LEDs, including power up behaviour, signal detection, and fade state indication. Jumper links JP1 and JP2 are fully documented, allowing engineers to configure whether microphone signals are equalised or direct, and whether microphone audio is mixed with music or routed separately on the slave output.
Slave output options are explained in detail, including ST3, SMU, SZ1, and 0V terminals, with guidance on how each output behaves in relation to music, microphone signals, and zone specific volume and tone controls. The manual also provides a complete list of potentiometer functions, covering independent volume, bass, and treble adjustment for each zone, microphone level and tone, and slave output volume.
This supplement is the correct technical reference for configuring, servicing, and fault finding Sound Leisure MK8 amplifier systems, and is not intended as a standalone user manual.
