User manual AUDIO TELEX ACM120RC

[. . . ] Adjusting the bass control in a counter-clockwise direction will provide up to 12 dB of bass cut @ 100 Hz. Tfeble Tonal Contfol: Setting this control in the centre position will give an overall flat feble response to the output of the amplifier' Adjusting the treble control in a clockwise direction will provide up to 9 dB of treble boost @ lOK Hz. Adjustinglhe treble control in a counter-clockwise direction will provide up to 9 dB of treble cut @ lOK Hz. MaStef OUtpUt This controls the overall output level of the amplifier depending on the levels set for the individual input mix channels as detailed above. Start with the control set to Level 0 and turn clockwise until the desired output level of the amplifier is reached Page Chime Button: This allows the user to disable or enable the Pre-Announce Chime. This switch does not however activate the chime. [. . . ] Press the desired storage channel (numbered I to 6). The radio station chosen is then stored in that memory location. You may automatically search for radio stations by operating the up and down arrow buttons. The receiver will search for and automatically lock on to threshold signals in the frequency band you have selected. Continue to press the up or down arrow buttons to resume your search or to fine tune any station selected. Cassette Player (ACM120RC Only): The cassette player has 3 unique controls, one each for Eject, Rewind (REW) and Fast Forward (FF). In addition, there is a gain control located on the receiver module that controls the output level ofthe cassette deck (and, when a cassette is inserted, has priority over the receiver as detailed above). The cassette player may be monitored and previewed in exactly the same fashion as the receiver. The cassette player will begin playing immediately a cassette is inserted though the slot in front of the cassette player. The REW and FF buttons will shuttle the cassette backwards or forwards respectively. Pressing both the REW and FF buttons together will reverse the playing direction ofthe cassette player and effectively change the side ofthe cassette being played. Pressing the eject button will eject the cassette and switch back to the receivers output. If you do not want to switah immediately back to the receivers output when you eject the cassette, make sure that the gain control on the receiver is turned fully counter clockwise.

The operating voltage is 240 VAC @ 50 Hz or tl0 vAC @ 60 Hz. The AC power voltage level is not extemally user adjustable but is factory pre-set. The inlet is equipped with an inbuilt AC fuse holder fitted with a 4 Amp fuse plus a spare. Please ensure that the mains power cord is disconnected before attempting to check or replace this fuse. I Direct Output Terminal Strip: The screw terminals on the left hand side of the strip allow access to the direct speaker outputs of the amplifier. The screw terminals on the right hand side are for activation of the in-built 4 tone generator. Reading from left to right the terminals are: . Low Impedance Common (use with 4 or 8 ohms) o . o 4 Ohms 8 Ohms Constant Voltage Common (use with 70v or l00v) 70 100 Volt Line Volt Line Spare Tone Generator Common (use with one of the 4 tones listed below) Pre-Announce Chime Alert Tone Bell Chime Evacuation Tone be no less than 80 Ohms. Note: The minimum impedance (or maximum load) at 100 Volt line should Switched Outputs Terminal Strip: Reading from left to right, these screw terminal pairs correspond to the switched 100 volt line outputs and are numbered 6 through 1 as indicated on the front panel of the amplifier. [. . . ] This pot adjusts the level for all 4 tones. Tones available on the ACMI20R and ACMI20RC include: o Evacuation Tone (to Australian Standard A52220. 1. 2) o Alert Tone (to Australian Standard A52220. 1. 2) o Bell Tone TOng GgngfatOfS: o Pre Announce Chime MUting: A VOX muting card is installed in the ACM120R and ACMI20RC. This feature provides automatic muting of some channels when others are active. It is normally used so that a paging microphone can have priority (by muting) over background music. VOX muting is available from channels I and 2 meaning that any signal on channels 1 and2 (mic or line) will mute channels 3 & 4. [. . . ]
