Description
The AMIS120 is a 4 channel, 120 watt mixer amplifier suitable for rack or desk mounting. The amplifier is a self contained compact unit of solid steel construction.
Inputs
The AMIS120 has four universal input channels with separate level controls. Each channel will accept balanced or unbalanced microphone,line and auxiliary inputs. The unit has industry standard XLR microphone sockets and dual RCA auxiliary sockets for each channel. An electronically-balanced 600 ohm telephone input for paging is also provided. An insert point is also featured on the rear panel for those applications where an additional EQ or feedback eliminator may ber equired.
Outputs
The AMIS120 features 70 volt, 4 & 8 ohm isolated transformer outputs,plus a tape recorder output by means of dual RCA sockets. A balanced700mV XLR output is also provided to feed up to six power amplifiers. Avox triggered relay output is also available on the rear panel for activation of external devices from the vox muting circuit. In most cases this would be used as a muting bypass relay, which when used with the appropriate external attenuator will maintain paging levels irrespective of the attenuator setting.
VCA Control
The master volume can be controlled remotely. External VCA control would normally be via a pot connected to a two wire rear panel barrier strip.
Speaker Zone Selector
A six position push button speaker zone selector with overriding “all call”is located on the front panel. Each of the six zone selectors switch the 70volt speaker line output to six separate speaker zones. The “all call”selector overrides all 6 zones regardless of their on/off condition and places the 70 volt output to all six zones.
Tone Generator
The AMIS120 comes standard with an in-built four tone generator module. Tones include Bell, Pre-Announce Chime, Alert Tone and Evacuate Tone. Any of these tones may be activated from a simple contact closure connected to the rear panel of the amplifier. A Pre-announce defeat switch is located on the front panel.
