1. INTRODUCTION

The Australian Monitor Installation Series AMIS26 is a high quality 2 input, 6 output distribution
amplifier. The AMIS26's 2 inputs can be balanced or unbalanced and each input's sensitivity
can be switched between Mic and Line level. 24 VDC Phantom power is individually
switchable per input and for ease of setup, a four segment LED level meter is provided per
input. Each of the AMIS26's inputs is individually assignable to any of the 6 outputs via front
panel DIP switches. Outputs can be balanced or unbalanced and feature up to 30dB of
attenuation, so they can be run as any combination of line level or mic level outputs. Ample
label space is provided for both inputs and outputs and the AMIS26 is powered via a supplied
24VDC power supply. The AMIS26 provides a low noise, feature packed, signal routing
solution to cover a wide range of installation needs at a contractor friendly price.

1. INPUT LEVEL CONTROL(S)

The input level controls are screwdriver adjustable trim pots. The input level controls can
boost or cut the input signal by up to 15dB.

2. LEVEL METER

These 4 segment LED meters show the strength of each of the AMIS26's input signals. LED
segments are calibrated to the following level markings and show the following colours:

3a. OUTPUT LEVEL CONTROLS

The output level controls are screwdriver adjustable trim pots. These level controls
attenuate the output level, with a range from -60dB at 'Minimum” position to 0dB at
“Maximum” position.

3b. INPUT ASSIGN SWITCHES

These recessed DIP switches assign input A and input B to a desired output.

4. POWER LED

This blue LED indicates the unit is powered “on”.

1. INPUT A/B CONNECTORS

The balanced XLR inputs can be used as Mic or Line level inputs and are switched
between input sensitivities via internal DIP switches accessed through the lid (see internal
adjustments section page 7). The dual RCA inputs are Line level inputs only and are
internally summed to mono.

2. OUTPUT CONNECTORS

The AMIS26's outputs can be either balanced XLR or unbalanced dual RCA's. Both these
outputs can be switched between Mic level & Line level via internal DIP switches accessed
through the lid (see internal adjustments section page 7).

3. 24VDC POWER CONNECTOR

This 2.1mm connector accepts power from the provided 24VDC power supply.

4. EARTH Stud

In some circumstances it may be necessary to ground the unit to eliminate noise in the
system. This can be done by using this earth stud.

NOTE: This stud provides a connection to chassis ground. Audio ground is internally

tied to chassis ground.

4. INTERNAL ADJUSTMENT

NOTE: The following adjustments involve access to the inside of the AMIS26 and should

only be attempted by a qualified technician. All internal adjustments are
accessible through the lid of the AMIS26. Always turn off the DC power and
remove the DCpower cord before accessing the insideof the AMIS26.

selected to the “on” position will switch the
balanced XLR input to Mic level. The “off” position
will switch the balanced XLR input to Line level. The
Default setting is Line level.

NOTE: This switch does not effect the sensitivity of

the unbalanced dual RCA input.
