This can be changed by setting the corresponding internal dip switch (IFB and TALK) to `on' (see section 8. 0 Internal controls / Dip switches). TO INCREASE LED LIGHT INTENSITY OF MIC MUTE, BUZZER MUTE, AUX AND IFB see point 21 `Set up lock'. User manual PS 6379 / Issue 1 © 2006 ASL Intercom, Utrecht, The Netherlands 9 7. 0 REAR PANEL CONTROLS & CONNECTOR 28 EXTENDED STATION LINK This connector is used when 2 units (either 2 x PS 6379 or 1 x PS 6379 with PS 4379) should be linked to form a 10 or 12 channel unit. When linked, 1 station will be the master with an active speaker and gooseneck/electret microphone. The speaker and microphone of the other unit will be switched off. The CALL ALL and TALK ALL signals will also be sent to the channels of the extended unit. 29 NEAR STATION LINK This connector is used to prevent system feedback when two PS 6379 / PS 4379 are used close to each other in the same room. This connection will dim the listening level should the `near station' talk on the same channels the `linked' station is listening to. The dim factor can be adjusted per channel by pressing and holding the `set up lock' button and pressing and holding the TALK button of the channel. The adjustment is done by turning the Aux level/ IFB dim knob. 30 GPIO This 9-pin connector is a general purpose in - out connector. The settings are as follows: - Pin 1 = GND - Pin 2 = GPIO output 1 (default=microphone functioning, active = high) - Pin 3 = output 2 (default=External power supply is used, active = high) - Pin 4 = Relay common contact - Pin 5 GPIO input 2 (default=mic mute all button, active = low) - Pin 6 = GPIO input 1 (default=buzzer mute all button, active = low - Pin 7 = GPIO input 3 (default=tall all button, active = low - Pin 8 = Relay normally open contact - Pin 9 = Relay normally open contact 31 LINE connector (per channel) These XLR-3 connectors are for connecting the PS 6379 to the remote stations, via standard microphone cable. There are two connectors for each channel. Audio wire 32 SYSTEM LINK connector Input for the cable of an external party-line Intercom system which has its own power supply. If any or all of the channels are to be connected to another intercom system, then these connectors will accept the communication signals from the other system without impedance problems and without using power from the other system. 33 LIFT / GROUND switch With these switches the pin 1 of either the AUX input, Program input or IFB input XLRs are lifted from ground when in `Lift' position. 34 AUX INPUT connector (auxiliary) This XLR female connector is electronically balanced and used to connect a line level signal which can be routed to any intercom channel by using the AUX buttons. Signal 35 PROGRAM INPUT connector This XLR female connector is electronically balanced and used to connect a line level signal which will be routed to the loudspeaker of the PS 6379 only. 36 IFB INPUT connector (AUX) This XLR female connector is electronically balanced and used to connect a line level signal which will be routed to the channels which are in IFB mode. Signal 37 MIC DIRECT OUT This XLR3 male connector is electronically balanced and outputs the pre-amplified microphone signal at line level. 10 User manual PS 6379 / Issue 1 © 2006 ASL Intercom, Utrecht, The Netherlands 7. 0 REAR PANEL CONTROLS & CONNECTOR (continued) 38 STAGE ANNOUNCE OUT This XLR 3 male connector is electronically balanced and outputs the pre-amplified microphone signal at line level when the STAGE ANNOUNCE button is used. SPEAKER An external speaker can be connected to this 6, 3 mm Jack. In this case the internal speaker switches off and the audio is sent to the external speaker.
