HPA4S- has two knobs for volume control, one for the left channel and one for the right channel. The majority of our customers like the high end positioning of music instruments: In a listening session, they use the two knobs as a balance and a three dimension control. This also gives our customers the possibility to equalize recordings which have one channel 'louder'. This version is also for people who hear one side louder than the other. Both versions have exactly the same electronics with DVD 24-bit 96 k-Hz sound quality!. The rugged housing is aluminium with top and bottom silver anodized and front and back natural anodized. It has a high quality standard 6,35 stereo jack for headphones plugin.

HPA4S- and HPA6S- Back There is a standard power connector for power hookup. We use a P,N and Gnd 3-pole for power so that hi-fi freeks can test different power cables to maybe improve the sound. There are special power cables on the hi-fi market that are supposed to be able to do this. A three pole cable is also easy to obtain in different countries for their special power outlets. They have two gold plated 'RCA' connectors for our CHNC-1-HE inter-connect cables. The aluminium back plate is natural anodised. The black rubber feet keep the relatively small housing from sliding on polished surfaces.
 

HPA4S- And HPA6S- Back The power switch is a push to toggle type. The 'CE' mark is for our declaration of conformity to the European low voltage directives, to the European EMC directives and the European CE Marking directive.
