Product description7ch power amplifier developed with consideration to combination with AVC-3000DSP. amplifier The AVM-3000 employs a 5-block independent all-discrete configuration of L, C, R, F (front effect), and S (surround), and has an orthodox design that emphasizes stability.For the power transistors, we use 4 each for the main L, R, and C high output power transistors called Pc150W.Furthermore, mutual interference is suppressed by separating from the transformer winding of the power supply section and feeding each block amplifier independently.It uses a thick aluminum heat sink and a highly rigid chassis.Equipped with a dedicated interface for pair linking with AVC-3000DSP.With this connection, the audio signals of each channel are transmitted in a balanced manner with +- polarity, and in particular, the L, C, and R channels have a symmetrical balanced configuration with respect to the ground up to the power amplifier, which is advantageous for sound quality. This is the configuration.Each of the five amplifier blocks is equipped with an input selector switch, so they can be used independently.The amplifier block side is equipped with an RCA pin jack and a Canon terminal, as well as phase switching and level volume.?Main specificationsModel 7ch power amplifierRated output(20Hz - 20kHz, distortion 0.003%) Main, center: 120Wx3 (6?)Effect: 60Wx4(6?)Frequency characteristics 5Hz to 300kHz +0 -3dBS/N ratio 108dB or moreChannel separation 100dB or more (L, C, R)Power supply AC100V 50/60HzPower consumption 580WExternal dimensions Width 473x Height 170.5x Depth 454.5mmWeight amplifier 32kg?The condition of the product is that there are no noticeable scratches or stains.We have confirmed the output on all channels.There are cracks and cracks in the side wood panels.The red knob that stops the + terminal of the main R is broken, so it spins idly.Other than that, I think its in good condition considering its age.For remote delivery areas, additional fees will be charged.
