AUSTRALIAN MONITOR AMIS120XL Series User manual

Description
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.
Inputs
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 stan-
dard 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. An electronically-balanced 600 ohm telephone input for paging is also provided.
Outputs
The AMIS120XL features 70 volt, 4 & 8 ohm isolated transformer outputs, plus a tape recorder out-
put 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 exter-
nal 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 level can be controlled remotely. External VCA control would normally be via a
pot connected to a two wire rear panel barrier strip.
Tone Generator
The AMIS120XL 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.
Muting
Multiple levels of VOX muting is standard on the AMIS120XL. A mic or line signal on channels 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 will maintain paging
levels irrespective of the attenuator setting.
Phantom Power
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.
Protection
Internal current limiting protects the amplifier from both overload and overdrive conditions.
Australian Monitor Installation Series amplifiers feature a protection network that
provides greater stability and performance. Our amplifiers are recognised world-
wide for their reliability and this is due to the extensive levels of current limiting
which protect the amplifiers from both overload and overdrive conditions.

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have eight universal input channels, each comprising of a balanced microphone
input with XLR female sockets and an auxiliary input using dual RCA sockets. A balanced XLR output to drive
additional power amplifiers shall also be provided. The master output may be controlled remotely via a VCA
control. An insert point is provided for the addition of signal processing. A vox triggered relay output (for
external devices) shall also be included.
The amplifier master section shall include one master gain control, three EQ controls, one at 100Hz with
12dB of cut and boost, one at 600Hz with 12dB cut and boost and the other with 9dB of cut and boost at
10kHz. Speaker outputs shall be transformer isolated at 70 volt, 4 & 8 ohms. The amplifier must be capable
of delivering 120 watts RMS into a 40 inductive ohm load, with less than 0.5% distortion measured at 1kHz
and with system hum and noise equal to or better than -74dB.
The amplifier shall be an Australian Monitor Installation Series model AMIS120XL.
