The AMIS120XL is an 8 channel, 120 watt mixer amplifier suitable for rack or desk mounting. The amplifier is a self-contained compact unit of solid steel construction. This amplifier features a status LED. The amplifier may operate from mains power or 24V DC.
The AMIS120XL has eight 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. Rear panel dip switches per channel allow the adjustment of line input sensitivity. An insert point is also featured on the rear panel for those applications where an additional EQ or Feedback Exterminator may be required.
The AMIS120XL features 100 volt, 70 volt, 4 & 8 ohm isolated transformer outputs, plus a tape recorder output by means of dual RCA sockets. A balanced 700mV XLR output is also provided to feed up to 6 power amplifiers. A vox 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, such as the Australian Monitor ATC5143FS, will maintain preset paging levels irrespective of the attenuator setting.
The master volume level can be controlled remotely. External VCA control would normally be via a 500k pot connected to a two wire rear panel barrier strip.
The AMIS120XL comes standard with a built-in four tone generator module. Tones include Bell, Pre-Announce Chime, Alert Tone (AS2220.1) and Evacuate Tone (AS2220.1). Any of these tones may be activated from a simple contact closure connected to the rear panel of the amplifier.
Multiple levels of VOX muting is standard on the AMIS120XL. A mic or line signal on channel 1 will mute channels 2 to 8, on channel 2 will mute 3-8, and channel 3 will mute 4-8. The muting function can be disabled via an internal link. A vox 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, such as Australian Monitor's ATC5143FS, will maintain preset paging levels irrespective of the attenuator setting.
Phantom Power (18 volts DC) is available from all mic inputs. A rear panel phantom power on/off dip switch is also provided per channel.
Internal current limiting protects the amplifier from both overload and overdirve conditions. Australian Monitor Installation Series amplifiers feature a protection network that provides greater stability and performance. Australian Monitor amplifiers are recognized worldwide for their reliability and this is due to the extensive levels of current limiting which protect the amplifiers from both overload and overdrive conditions.
