Introduction
Mini Stereo Power Amplifier
The AMP20 is a Mini Stereo Power Amplifier with a power rating of 2 x 15 Watt, which lends itself perfectly to small speaker systems requiring compact and economical audio solutions. It offers the ideal solution for applications such as classrooms, offices and meeting rooms where a small amount of speakers are required.
The compact size and very high efficiency makes it perfectly suited to be hidden in a closet, on a false ceiling or mounted under a desk or table.
The combination of the stereo balanced line and microphone input make it perfectly suited for applications where it should be used in combination with projection screens and video sources while a microphone is connected. Two gain potentiometers make it possible to control the sensitivity and balance between music and speech, while a switch allows bridging of the output channels to obtain one channel with merged output power.
A remote wall mixer can be connected for applications where local mixing of the inputs is desirable, while large distances can be covered between the source and amplifier using simple CAT5 twisted pair cabling. The volume controller input allows connection of an additional wall controller for overall volume control.
The Class-D Amplifier technology, standby mode and included switching power supply makes this device compliant to Energy Star 3.0 and other strict energy efficiency and environmental requirements.

Overview AMP20
Front panel
The front panel of the AMP20 contains all the control and indicator functions.
Two gain control potentiometers are provided with which the gain of the line and microphone inputs can be regulated separately and the balance between the music and speech can be set.
A slide switch provides the possibility to switch the amplifier between Stereo and Mono / Bridge mode. If this switch is set to stereo, the output will be stereo. If its set to Mono / Bridge, the Left and Right channels will be summed to a dual–mono output.
Three indication LED's for ‘ON / STANDBY’, ‘SIGNAL’ and ‘CLIP’ indicate the operation mode of the amplifier. The ‘ON / STANDBY’ LED will turn green when the device is switched ON and running. When no signal with a sufficiently high level is detected for a certain period of time, it will switch to standby mode and this LED will turn orange. The ‘SIGNAL’ LED will turn green when a signal with a sufficiently high level is detected and the ‘CLIP’ LED will start blinking when the signal reached the clipping level and the internal limiter starts working.
Rear panel
All necessary connections of the AMP20 are provided at the backside of the device. An overview and explanation of all the connectors and possibilities is given below.
1) 24 Volts power connector:
The 24 Volts power supply connection is provided on the left side of the AMP20's rear panel. The included power supply (PSD241) should be connected to the terminal block connectors. Pay attention to the polarity when connecting the power supply.
2) Loudspeaker output:
The loudspeakers should be connected to the 4-pins 'AMP OUT' Terminal Block connector. Depending on the position of the Stereo and Mono / Bridge switch on the front panel, the corresponding audio output will be available here. When used in Stereo mode, the left loudspeaker(s) should be connected to the two leftmost terminals and the right loudspeaker(s) should be connected to the two rightmost terminals. When used in Bridge mode, the loudspeaker(s) should be connected to the two outer terminals.
3) Remote wall mixer and Volume controller connections:
Two RJ45 connectors are provided for connecting Remote wall mixers and external overall volume controllers. The connections on these extension ports should be made by using a simple CAT5 twisted pair (or better) cable in a straight pinout configuration. The pinout and colour coding is described on Chapter 1 of this instruction manual.
The remote wall mixer connection carries the supply voltage to the wall input unit and a stereo differential audio signal from the wall input unit to the amplifier.
The audio signal coming from the remote wall mixer will be proportionally mixed with the direct line and microphone inputs.
The volume controller connection carries a negative supply voltage to the external volume controller and has an input for a variable negative voltage. Depending on this voltage, the overall volume will be regulated. When no external volume controller is connected, the overall volume of the device will be defaulted to its maximum.
4) Balanced Stereo Line and Microphone inputs:
The balanced stereo line and microphone input are performed using 3-pins terminal block connectors.
All different kinds of balanced and unbalanced line level audio sources can be connected to the line inputs. Some examples are CD & MP3 players, Tuners, Laptops, DVD players, ...
The microphone input provides the possibility of connecting any kind of microphone without phantom power requirement.

Overview of the AMP20 setup
Connecting the AMP20
1) Connecting audio inputs
Connect all your audio sources (CD & MP3 players, tuners, microphones, ...) to the audio inputs of the AMP20. All the direct audio inputs are performed using 3-pins terminal block connectors. For more information about the connections and wiring pinout, check Chapter 1 of this manual.
2) Connecting audio outputs
This suggested application uses a total of four loudspeakers. The AMP20 contains two speaker outputs (stereo) meaning that two speakers should be connected on every amplified output. The speakers must be connected in parallel and the load on each amplifier output channel should be 4 Ohm or higher.
3) Connecting the external units
The external (optional) wall volume controllers and remote wall mixers should be connected to the corresponding RJ45 connector ports. The connections should be made by using simple CAT5 twisted pair (or better) cabling in a straight pinout configuration. The maximum cable length between the external units and the AMP20 may not exceed a total cable length of 100 meters.
4) Connecting the power supply
The included power supply should be connected to the 2-pins Euro Terminal block connector. Watch the polarity when connecting the power supply.
Configuring the AMP20
1) Adjusting the input sensitivity & volume
The configuration of the AMP20 only includes the sensitivity adjustment of the inputs and the overall volume regulation. The sensitivity of the inputs can be regulated by the two potentiometers on the front panel of the AMP20. The correct regulation depends on the signal level of the connected sources and the requirements for each specific application. The regulation should be done experimentally, making a good balance between the music signal from the audio source and the speech from the microphone.
The line and microphone level signal coming from the remote wall mixer is mixed locally and the balance can be set using both push-lock potentiometers. The output level can be set using the big volume dial. This signal is mixed with the direct line and microphone inputs at equal levels.
After all sensitivity settings have been made, the overall volume control can be done using the VC3008/4008 volume controller.
