A1500.2 Dual Monoblock Power Amplifier with Mirror Image Technology

Regular price $ 8,999.99

The A1500.2 is a True Dual Mono Design providing better stereo separation and imaging as compared to traditional stereo amplifiers - the chassis being the only thing common between channels. In an effort to provide the very best signal to noise ratio and lowest distortion possible, 109 dB (A-weighted) and <.002% THD+N the amplifier utilizes a Mirror Image Design with positive and negative output signals of each channel generated using identically mirrored circuitry. Each of the two channels is also a mirror image of the other. A1500.2 operates the current amplifier devices in class A/B operation and the voltage amplifier devices in pure balanced Class A mode offering a realism and truth to the source never before available from a mobile power amplifier.

From a design standpoint, the A1500.2 utilizes separate PCBs for the voltage amplification stage and current amplification stage to maximize the signal to noise ratio so that it's dead silent. It has been designed from the ground up around the highest quality components available at any cost, including; Nichicon Fine Gold™ capacitors, Nichicon Muse™ audio capacitors, (14) On-Semiconductor complementary bipolar junction transistors per channel, and non-inductive resistors, all assembled on 4-layer heavy copper PCBs! Its dual mono channels can be wired as a single channel with double the output voltage for applications where high power is required. Finally, it includes a pair of gorgeous LED output meters to indicate actual amplifier power for each channel as well being used for self diagnostics in a fault condition.
