[. . . ] 26 BUZZER MUTE (per channel) With these pushbuttons the buzzers of all stations connected to that channel can be muted, until the BUZZER MUTE button is switched off again. 27 IFB (per channel) With these pushbuttons a channel can be put into IFB Mode. This is used for monitoring purposes and one way communication from i. e. If a channel is put into IFB mode, the AUX button of that channel will switch on automatically and the auxiliary signal of the IFB auxiliary input will be routed to that channel. If no IFB-Auxiliary is needed, it can be switched off by switching off the aux button of that channel. The AUX-input can also be routed to an IFB channel by switching the corresponding dip switch (IFB or AUX input for IFB) to 'on' (see section 8. 0 Internal controls / Dip switches). The TALK button of an IFB channel will be momentary and not latching and must be pressed while talking. When pressing the TALK button of an IFB channel, the aux volume will be dimmed automatically by 50 %. This dim factor can be adjusted (see point 17 AUX Level / IFB DIM). The TALK buttons of the intercom channels will switch off for as long as the IFB TALK button is pushed. 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'. 9 User Manual PS 4379 - Issue 1 © 2007 ASL Intercom, Utrecht, The Netherlands 7. 0 REAR PANEL CONTROLS & CONNECTOR 28 EXTENDED STATION LINK This connector is used when 2 units (either 2 x PS 4379 or 1 x PS 4379 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. NEAR STATION LINK This connector is used to prevent system feedback when two PS 4379 / 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. 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 LINE connector (per channel) These XLR-3 connectors are for connecting the PS 4379 to the remote stations, via standard microphone cable. There are two connectors for each channel.
