Custom installation (C.I.) use
The 840E features a Control Bus input/output that
allow | In | In | Out |
|
|
| |
(positive logic, TTL level) to be received electrically |
|
|
|
by the unit and looped to another unit if desired. |
|
|
|
These control commands are typically generated |

by custom installation
An IR Emitter Input is also provided that allows modulated IR remote control commands to be received electrically by the unit. Commands on this input operate the unit only and are not looped out demodulated on the Control Bus Output.
An RS232C port is also featured which allows the 840E to be controlled by C.I. systems.
In addition the unit features ‘direct’ IR/Control codes as well as toggle codes for some of their features to simplify programming custom installation systems. Special direct On/Off and Mute commands can be accessed on the supplied remote control for teaching into C.I. systems as follows:
1.Press and hold the Standby/On button. The remote first generates it's standby (toggle) command. Keep the button held down, after 12 seconds an amplifier “On” command will be generated. If the button is kept held down for a further 12 seconds, an amplifier player “Off” command is generated.
2.Press and hold the Mute button. The remote first generates it's mute (toggle) command. Keep the button held down, after 12 seconds a “Mute on” command will be generated. If the button is kept held down for a further 12 seconds, a “Mute off” command is generated.

Troubleshooting
There is no power
Ensure the AC power cord is connected securely.
Ensure the plug is fully inserted into the wall socket and is switched on. Check fuse in the mains plug or adaptor.
There is no sound
Make sure the unit is not in Standby mode.
Check that source component is properly connected.
Check that Input 8 (Rec In) is not switched on (unless a tape input is required).
Check that your speakers are properly connected.
Make sure unit is not in mute mode.
There is no sound on one channel
Ensure that balance control is in the correct position.
Check speaker connections.
Check interconnects.
There is a loud buzz or hum
Check turntable or tone arm for ground and connection lead fault. Ensure no interconnects are loose or defective.
Ensure that your tape deck/turntable is not too close to the unit.
Unable to make or play tape recordings
Check that Input 8 (Rec In) and Rec Out have been connected correctly.
There is weak bass or diffused stereo imaging
Ensure that speakers are not wired out of phase.
The remote handset will not function
Check that the batteries have not expired.
Ensure that nothing is blocking the remote sensor.
