Equalizer Controls

Three different controls for three frequency bands. Those volume controls will increase or decrease bass and treble or add some presence to the sound.

Manual Priority Terminals

These two terminals, when shorted, will mute incoming signal from AUX and CD inputs, thus giving priority to the Telephone Paging and Microphone. These are especially useful when a table microphone with switch is part of the installation.

Speaker Terminals

These terminals are offering 3 low voltage outputs 4 Ω , 8 Ω , 16 Ω depending on your speaker combination. A 70V/100V commercial output is also available. Please note that one wire only should be connected to COM screw and one wire to the selected impedance or voltage. Multiple combinations cannot be done at the output level.

Four different types of connections are provided. The low impedance section: 4 Ω , 8 Ω , 16 Ω is designed for a small amount of speakers to be connected to your amplifier. The 70V section is especially designed for a multiple speaker distribution. When using the 70V output, speakers have to be equipped with 70V transformer. The maximum amount of speakers to be placed on your distribution line is in relation to the power allocated to each speaker. The total wattage set on the secondary side of the transformers on your speaker line must not exceed the maximum RMS output power: 30W or 60W.

Failure to respect this may cause permanent damage to the amplifier.

Microphone Input

This ¼ ’’ jack is a two conductor unbalanced microphone input. If you wish to use a low impedance microphone on a balanced line with a long cable, we recommend that you use an AM-

15 adaptor to do so. If you choose to use a Table Top microphone with an enunciator switch, keep in mind that the switch should be connected to the two priority terminals.

Music on Hold

This output will feed music on your telephone system for people waiting to be answered. A dedicated input should be available on your telephone system. Please refer to a qualified technician if you can’t identify this input. Outgoing signal should be connected to G and H.

Volume control is located next to the terminal in order to provided proper level of music on the phone system.

 

Telephone   Paging   Input  

 

This   special   input   (terminals   1   and   3)   will   allow   you   to   page   in   your   PA   system   using   your   own   telephone   set.

 

Pin   2   is   Ground   and   Pin   4   is   for   manual   priority   switching.

  Any   signal   going   through   Pin   3   with   automatically   triggers   the   priority   system   without   any   manual   intervention.

  At   the   end   of   the   announcement,   the   system   will   return   to   its   normal   operation.

  A   Gain   control   is   located   next   to   the   input   in   order   to   increase   incoming   volume   if   necessary.

  Final   adjustment   will   be   made   with   the   Tel   Paging   volume   control   located   on   front  

  panel.

  

 

Recommandations  

Keep   your   amplifier   away   from   excessive   humidity,   dust   or   grease.

  This   unit   has   sensitive   components   that   can   be   affected   in   a   difficult   environment.

  If,   at   one   point   during   its   usage,   the   fuse   on   the   AC   line   needs   to   be   changed   make   sure   that   the   replacement   is   of   the   same   value.

  It   is   important   that   you   try   to   identify   the   reason   for   this   failure.

  This   will   most   likely   prevent   further   damage   to   your   amplifier.

  Any   service   work   on  

  this   unit   should   be   performed   by   a   qualified   technician.
