AMIS120P, 120 Watt Power Amplifier

Product Description

The AMIS120P is a 120 watt single channel power amplifier designed for commercial installations. It can

be used for either low impedance (4 or 8 ohm) or 70v/100v line speaker systems. The amplifier can be

mounted in a standard 19” equipment rack (rack ears supplied) or it can be mounted on a shelf or table. The

AMIS120P features a line level input (with parallel output) and is normally used with mixers, mixer

amplifiers or other power amplifiers. The AMIS120P also features 24 volt DC operation.

Front Panel Features Power Switch The black rocker switch on the right hand side of the front panel is used to switch the amplifier on and off. The ‘up’ position is on. When the amplifier is connected to an appropriate AC power source and is switched on, the blue power LED will illuminate. This switch will not switch DC power on or off in DC operation. In DC operation mode, the amplifier is always on and the blue power LED will always be illuminated.

The inlet is equipped with an in-built AC fuse holder fitted with a 4 Amp slow blow fuse plus a spare fuse. Please ensure that the mains power cord is disconnected before attempting to check or replace this fuse. Power consumption is 300 VA (max). 230V/240V Slide Switch The operating voltage of the amplifier is user selectable between 230V and 240V via a slide switch located on the right of the AC inlet.

Notes: The DC fuse is located on the circuit board. This is a feature of the AMIS series amplifier, which is equipped with a current limiting circuit preventing excessive DC current, thus eliminating the risk of blowing high tensions fuses. In the unlikely event that the DC fuse actuates, the output transistors should be checked, as it is probable that the amplifier has been subjected to very extreme conditions.

15. Do not drive the inputs with a signal level greater than that required to drive equipment to full output. 16. Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off. 17. Do not run the output of any amplifier channel back into another channel’s input. Do not parallel- or series-connect an amplifier output with any other amplifier output.
