Encyclopedia
HH Electronics is a British
amplifier
manufacturer that was founded in 1968 by Mike Harrison, Malcolm Green and Graham Lowes in Harston near Cambridge
, England
, where its first solid state
TPA Amplifier and other sound equipment were designed and produced. The company later moved to larger premises at Milton
, Cambridgeshire
, named the 'Dust Bowl' producing the first of the IC range of music amplifiers.
One of the first solid state transistor amplifiers designed and manufactured by HH was the TPA and AM series, which were used by many broadcasting studios, including the BBC.
The I/C100 Organ/Musical Instrument Amplifier, which gave a massive 100-watt
RMS
of undistorted power, was produced with musicians and the retail market in mind. The separate 412BL minor Lead/Bass Cabinet was also produced for the I/C100. The I/C100 was also put in to the form of a Combo matched with then, a pair of Celestion
12" Speakers
.
Following a move to Bar Hill
, Cambridge
, HH extended its range of music sound equipment to include models such as the MA100 Mixer Amplifier, V-S Bass, IC100L, V-S Musician (a two-channel 100-watt amplifier head that had a separate pre- and master control), housing them in a very slim format and combo enclosures. Many new speaker cabinets
were designed and put into production, such as the 212 & 412 Dual Concentric 212BL, 215BL, 412BL, 115PA Radial Horns and Bass Bin + Piezo.
Speaker chassis were also manufactured in-house under the supervision of HH Acoustic in order to match the amplifiers and speaker cabinets.
Continuing designs brought along another of the first 19-inch rack
mountable studio quality power amplifiers, the S500D, producing nothing less than 500 watts RMS of power per channel, and the V-series amplifiers, including the V100, V200, V500 and V800 MOSFET
.
HH moved premises again around 1985 to Clifton Road, Huntingdon
, Cambridgeshire
, and began to develop new amplification products, such as the VX Range of 19" Rack Amplifiers, MXA and Invader series speakers.
In the 1990s they were bought out by Laney Amplification
.
HH Electronics now resides in the West Midlands
and it's current range reflects the company’s continued drive to offer excellence in performance with outstanding value and a close understanding of the end-user and is still designed in the UK.
