Where to buy?

The AMP20 is a mini stereo power amplifier with a power rating of 2 x 15 Watt, that lends itself perfectly to small speaker systems requiring compact and economical audio solutions. It offers the ideal solution for applications such as class rooms, offices and meeting rooms where only 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, with microphone input, makes 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 for 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 the highest energy efficiency and environmental requirements. A variety of optionally available mounting brackets for the AUDAC S-Box product range are allowing desk, closet or 19” equipment rack installation.

FAQ

Answer

As the power consumption of an amplifier, strongly depends on how hard the amplifier is driven, measurements are provided for various loads: idle, 1/8 of average full power, 1/3 of average full power, and full power.

Idle 
Current draw at idle or with very low signal level

1/8 Power: Pink Noise
Amplifiers are tested using pink noise signals to simulate real-world speech and music signals.  It approximates operating with music or voice with light clipping and represents the amplifier's typical "clean" maximum level, without audible clipping. This 1/8 power signal provides a very good approximation of how hard an amplifier would be driven by typical real-world speech/music signals, assuming those signals were being driven as loud as possible without clipping the amplifier.

1/3 Power: Pink Noise
1/3 Power Pink Noise is similar to 1/8 Power Pink Noise, except that it is a significantly more powerful input signal. It approximates operating with music or voice with very heavy clipping and a very compressed dynamic range. This 1/3 power signal provides an approximation of how hard an amplifier would be driven by typical real-world speech/music signals, assuming those signals were being driven loud enough to clip the amplifier heavily, and produce severe, audible distortion.

Full Power
Current draw at full power is measured with a sine wave at its maximum possible level. However, it does not represent any real-world operating condition and represents the absolute extremes that an amplifier could ever experience.
