We've added a 4x 150 Watt digital amplifier for those that don't need the 2,000 Watt per channel of the EA1161 and EA1162 amplifiers. The looks are the same, the size too (1U rack mount). Pro-audio for halls, pubs, bigger meeting rooms etc.

The EA35A in-wall amplifier module fitted into a dual gang Fast-install kit proves to be the favourite choice for installers. The faceplate has 2 audio inputs to a 30 watt stereo amplifier with VGA, composite video and USB connections See more here...

Our new range of EA35 In-wall amplifiers for the classroom include single gang, dual gang and a  module with built-in or external power supplies to suit the installation.  With dual in-puts users can listen to sources and use voice re-inforcement.

The EA1144 50 Watt Amplifier with infrared microphones, and with two audio inputs provides a total solution for classroom sound and overcomes the problem of interference between systems in adjacent classrooms that are suffered by VHF wireless systems - a complete classroom or meeting room sound re-enforcement system

The EA1161 and EA1162  are the latest additions to our Pro-audio range of products. This stunning digtal amplifier is 1U high, rack mounted "weighing in" at 10 kg. The 2 channel version drives 2,000 Watts per channel into 2 ohm speakers, the 4 channel drives 1,000 watts per chanel and both sets of kit cope with 2 ohm, 4 ohm and 8 ohm speakers. More details here...

While setting up a multiple speaker test on the EA35 in-wall amplifier we unwittingly used a faulty mini jack lead which was open circuit (on all wires !!) the mains hum level that resulted when we turned the amplifier on was very loud (>110 dB) and louder than the test tone (the test area had lots of dangling mains cables for the test equipment and power supplies etc not unlike the mess found in some false ceilings that I've seen)

The hum was just from the pick-up of mains interference with no direct connection.

There was no detectable hum at all from the amplifier without a cable connected to the input nor with the correct cable connected whether or not it was plugged into the tone source

It just reminded of some of the "faulty amplifier" reports that we receive

So the message is always check the cables first..... the cables are much more likely to be damaged when snagged during installation than the amplifiers.

Incidentally the tests proved that 2x 8 ohm or 4x 8 ohm speakers work really fine on this neat Class D digital amplifier with twice the "loudness" on the 4x 8 ohm (>3 dB)

 Introducing the new version of the popular EA1128v.2 stereo power amplifier with improved connectivity - it now has 5 speaker outputs making it easier to use in the classroom when more than 2 speakers are required (4x ceiling speakers and a centre speaker for instance). Check here for full details and specification of the EA1128v2

EA1172 is another Pro-audio power amplifier in the Edis range of amplifiers for school halls, events and places of worship where that bit extra is needed. Ideal combination with E68 Speakers and  UHF wireless mics in our flight case amplifier set. See full details of the EA1172 amplifier here
