Introducing ten new amplifiers, all made in the United States of America. Orbiting Planet Audio are eight 2-Channel amplifiers, a pair of 4-Channel amplifiers, and a

P502, P1002, P1502, P2502 and P225HC feature a pair of individually-adjustable high and low pass crossovers, a low frequency variable boost control, independent routing switches for both the amplifier and line out sections. In addition, the low and high pass crossovers can be cascaded to form a triamplified systems.

Models HVT752, HVT7100 and HVT7150 have identical features to the above amplifiers, with one addition - the main preamp features a pair of vacuum tubes as its active elements.

One

of

the four channel amps, P704, has three sets of crossovers, two high pass and an 18 dB/octave low pass. Of course, all are independently adjustable. Selector switches allow both pairs of channels and the line output to pass flat frequency, high and low pass signals. crossover.

HVT754 is identical to the P704 with the addition of the vacuum tube front end. The P706 is an extremely flexible amplifier. Four crossovers allow this unit to perform many different functions.

One pair of channels is controlled by a high pass crossover. The second pair is controlled by both a high and a low pass crossover, so a

bandpass function can be achieved. The last pair have a 24 dB/octave low pass crossover.
