120W, 6 Channel Mixer Amplifier

SA120

Description

The SA120 is a high quality system amplifier which can be powered by AC mains or 24 volts

DC. It is sturdily constructed with a solid steel chassis and standard rack mounting front panel.

Generous heat sinking and a conservatively rated 300vA toroidal power transformer ensure

that the amplifier comfortably meets specifications.

Inputs

The SA120 features six universal channels with separate channel gain controls. Each channel

will accept balanced microphone or unbalanced line and auxiliary inputs. The unit has indus-

try standard XLR microphone sockets and dual RCA auxiliary sockets for each channel.

Outputs

The SA120 features 100 volt, 70 volt, 4 & 8 ohm isolated transformer outputs. A separate male

XLR socket provides a 700mV (max.) balanced transformer isolated output for connection to

additional power amplifiers. A separate tape recorder output is supplied by means of dual

RCA sockets.

Insert Point

A 6.35mm insert jack between the pre-amp and power-amp stage is accessible on the rear panel. It

is ideal for a Graphic EQ, FBX Feedback Exterminator or any other type of line in/line out processor.

DC Operation

A trickle charge circuit automatically provides a maximum of 300mV to a stand-by battery con-

nected to the 24 volt DC input.

Tone Generator

A four tone module (ATC5488) is an optional accessory. The unit plugs in to a receptacle inside

the amplifier. A choice of any one of four tones may be selected including Bell, Pre-announce

chime, Alert tone (AS2220.1) and Evacuate tone (AS2220.1). Any of the tones may be activat-

ed from a remote point by means of external connections which may be wired to the rear panel

of the amplifier. Activation of any tone automatically mutes inputs 2 to 6 of the amplifier.

Muting

The SA120 is equipped with a multi-pin receptacle on the circuit board which accommodates

the optional TX3014 two channel muting module. With the TX3014 installed, signal present on

channel 1 will mute all remaining inputs (2 to 6). When signal is present on channel 2, inputs 3

to 6 are muted. A single channel muting module TX3010 is also available. This unit plugs into

the same socket in the amplifier and will provide muting of channels 2 to 6 when signal is pres-

ent on channel 1.

Protection

Australian Monitor Installation Series amplifiers feature a protection net-

work that provides greater stability and performance. Our amplifiers are

recognised 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.
