meade916 Posted December 29, 2019 Report Share Posted December 29, 2019 Look what i got for Christmas! WOW!! thank you so much Tony and Juan!!! The A1500.4 is a True Dual Stereo 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 <0.027% 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. A1500.4 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 A1500.4 utilizes separate PCBs for the voltage amplification stage (and each of the 4 channels has its own) 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, (8) On-Semiconductor complementary bipolar junction transistors per channel, and non-inductive resistors, all assembled on 4-layer heavy copper PCBs! Its dual stereo channels can be wired as two single channels with double the output voltage for applications where high power is required. Finally, it includes two pair of gorgeous LED output meters to indicate actual amplifier power for each of the 4 channels as well being used for self diagnostics during a fault condition.

LindaOmar Posted December 21, 2022 Report Share Posted December 21, 2022 (edited) Wow, that's a fantastic gift you got, congrats! When I want to make a cool and heartwarming gift for my loved ones, I usually go to places like jetgiftbaskets.com and pick the most interesting and delicious-looking basket, but what you got is pretty good too, lol. A lot more expensive, though, but I'm sure it's worth the money. This beast is a great achievement for mobile audio amplification and a huge advancement compared to the competition. I also really appreciate your reviews on other things and look forward to the next videos. Edited December 23, 2022 by LindaOmar Quote Link to comment Share on other sites More sharing options...
