1. Conference microphones input: connect conference microphones from the PACONF-E manufacturer
only ! Switch off mains current supply and turn all volumes down before connecting any microphones to
the system. Start by connecting the chairman’s microphone’s output rst, then daisy chain the delegate’s
microphones to the input of the chairman’s microphone and so on... Always use balanced cables.
2. Extra microphone input: balanced input to connect an extra microphone or line level signal.
3. Mic/line switch: push the button to switch the EXT MIC INPUT to mic level or line level.
4. Low cut switch: push this switch to activate the low cut lter on the EXT MIC INPUT. This is useful to
eliminate pop noise from microphones, or to improve intelligibility.
5. Line in: Connect an external line level source to these RCA connectors. Set the level and tone relative
to the conference microphones using the controls on the front panel.
6. Record output: on these RCA connectors, the PA-CONF-E line level output is present, not infl uenced by
the master volume control ! This can be usefull for recording purposes. Both L and R buses reproduce a
mono line level signal.
7. Main output: transformer balance main output on XLR connector (1 = GND, 2 = signal +, 3 = signal -).
When connecting to an unbalanced input, connect pin 1 to pin 3 (GND). The + is available on pin 2. The
output can be switched from line level to microphone level.
8. Mic/line switch: to switch the main output to mic or line level.
9. Conference microphones send/return: RCA connectors used for connecting external microphone
feedback elimination devices. Please note that the connection bridge between send and return must be
present when not using an external feedback eliminator. The RCA connector labeled “SEND” carries
the conference microphone’s signal, the “RETURN” connector is routed towards the PA-CONF-E’s main
output.
10. IR input: connect an optional infrared receiver eye to this TRS minijack. This can be useful to extend
the range of the remote control, or when the PA-CONF-E unit is installed on another location. Use
screened cable only. Maximum allowed cable length depends on cable type and external interference
caused by other wires, magnetic elds, cell phone signals…
11. IR output: this TS minijack will pass the IR signals received by the front IR eye or from the optional
external IR receiver. When you connect an optional IR transmitter to this connector, you can pass
through IR signals for other devices.
