Several new products from Korg this month, together with interesting developments on the professional PA amp scene from BGW systems.

First the Korg EPS-1, an electronic piano and string machine related to but smaller than the 80S Symphonic Piano. The EPS-1 has a 6¼ octave keyboard and an impressive specification first revealed at the opening of the new Rose Morris Capital Keyboard Centre in Shaftesbury Avenue, London, during late October.

From left to right the angled control panel features the following: Master Volume, for headphones and Line Out, Three Band Equaliser for Piano. Presence Control (pull on), Piano I & II, Electronic Piano I & II, Clavinet I & II, Off. Stereo Chorus or Tremolo with Speed and Intensity. Key Dynamics control to adjust keyboard action to personal taste. Key Transpose control for entire keyboard. Strings Attack/Key Dynamics and Release. Two Band Equaliser for Strings, Strings On/Off and Volume.

The keyboard will be available early in 1983.

Korg's Rhythm 55B is an updated version of their popular KR55 preset rhythm box. The same superb voicings, including Rimshot, Cowbell and Clave, are now combined with two alternative patterns on each of the 48 rhythms, Intro/Fill In facility and a variable Swing Beat on the Jazz Rhythms. As before, the individual volumes of the instruments are adjustable and there's a trigger output for sequencers giving a wide variety of options.

The Korg Programmable Digital Delay SDD-3000 offers a wide range of delay times, modulation waveforms and attenuation options.

The input has alternative levels of -30dBm, -10dBm or +4dBm together with a wide-ranging level control, and frequency response is 20Hz to 17kHz. Low Cut and High Cut Filters are included and delay times available are 0 to 1023 msec, in one msec, steps.

Regeneration and Hold are available, together with Triangle, Square, Random and Envelope modulation. The unit comes in a standard 19 inch rack and will be available early in 1983.

Also on its way is Korg's first programmable rhythm machine, the KPR-77. Programme chaining, multiple memories, individual instrument mixing, illuminated LCD status display, beat length selection, tape dump of programmes, individual trigger outputs and sync are just some of the advanced features available. Instrument voices and effects include Cymbal, open and closed High-Hat, High and Low Toms, Claps, Tom flam and Accent. There's also a headphone socket for private programming and checking.

Californian electronics company BGW systems have a range of power amps available including the Pro-line 7000, the 750B and the 750C.

The 7000 is a solid state quasi-complementary bridgeable design featuring Forced Air Cooling (by an internal fan), internal circuit breaker and ¼ inch connectors. The front panel has two input level controls, a rocker power switch and green LED power indicator, and the rear panel a mono/stereo switch to convert the amp to fully bridged mono operation. Sixteen 150W power transistors in each output stage give a total mono output of around 750W with generous headroom.

The 750C with clipping indicator LED's and the 750B with dual solid state VU meters each produce around 930W mono, or 285W per channel stereo. Each includes facilities for balanced XLR or unbalanced ¼ inch connectors, complementary output stage, error-sensing op-amp input stage and extensive circuit protection. THD is typically around 0.008% at 1kHz.
