WEM [Watkins Electric Music] BandMixer 100 Mark I - solid state mixer/amp 100 watt, 1976, made in England

Link: radiomuseum | wem-owners

This mixer / amp came in 1 versions.

One version had a stereo optionalthough you would need to link a slave amp to get stereo. It has a mono/stereo switch and stereo output sockets on the front.

The Bandmixer I do currently have is a standard mono version. It consists of 4 channels, each channel having 2 inputs, volume, bass and treble controls. There is no reverb, just a master volume slider, a slave output socket, and a stereo socket for linking an echo unit such as a Copicat.

Material Various materials

Bakelite chassis. These tweeters are some strange creatures having the dust cap fixed to pole piece by a brass screw, thusa rugged mechanical high-pass filter. The impact on frequency response from this is a broad peak centered around 12-14 kHz, 15 dB above basic level - and some 10 dB above the average response from the 8" driver.
Those who choose to run their tweeter from a single cap alone, usually 2.2 uF, certainly get some upper treble level!

Kemper Profiling Amplifier Head [Profiler Head guitar preamp in black]

Link: kemper-amps

Both the Rack and the Head (black version only) are available with a built-in Class D power amp. It produces 600 Watt @ 8 Ohm or 300 Watt @ 16 Ohm. The power amp was designed in Denmark by the renowned IcePower. It offers pristine sound quality, whether it is driving linear speakers or classic guitar speaker cabinets. 
The Class D technique makes for the most energy-efficient power amp solution, emitting only a minimum of heat. This reduces the need for heat-sinks, as well as minimising the overall size and weight. Combining this power amp with the Kemper Profiler turns the PowerHead and the PowerRack into a super smart, compact, all-in solution. The PowerHead weighs in at a little over 6kg. 
If required, you can switch off the built-in power amp, converting your powered Profiler into a line-level unit for recording purposes.
