Please always follow these instructions to help ensure against injury to yourself and damage to the system. 1) Read all safety and operatinginstructions before you operate the apparatus. Heed all warnings on the apparatus and in the safety and operating instructions. Do not use accessories or attachments not recommended by the manufacturer, as they may cause hazards and void the warranty. Do not operate this apparatus in high humidity areas or expose it to water or moisture. [. . . ] 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 %. 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 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 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. 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. 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. 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 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 4379 only. 29 33 34 30 35 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. 31 10 User Manual PS 4379 - Issue 1 © 2007 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. In this case the internal speaker switches off and the audio is sent to the external speaker. [. . . ] It develops a DC potential over the line impedance which will be sensed by each station and interpreted as a Call signal. 13. 0 TECHNICAL SPECIFICATIONS POWER SUPPLY Mains voltage 100 - 240 V AC 50/60 Hz (auto select) DC output voltage +30V +/- 2% DC Max. output current 2. 5A continuous / 3. 5A peak Circuit breaker delay time 0. 2 sec Automatic reset time 3. 0 sec MIC.
