JR Sound Co., Ltd.
About This Product
The HA-404Ⅱ is a 4-channel, 4-out, high-performance microphone amplifier for complete professional use. The specifications and performance remain the same, but it has become a renewed Type II with an emphasis on sound quality. Please listen to the sound quality. Equipped with 48V phantom power, -20dB pad, phase switch, variable high-pass filter, 16dB to 70dB gain switch, LED VU meter and variable gain adjustment VR, it is equipped with the functions necessary for a microphone amplifier.
Our microphone amplifier uses Rudahl's input microphone transformer and our original 3-layer winding transformer for the output transformer with a special connection.The output transformer drive also has a transistor buffer amplifier attached to the IC output, and is a class A drive that is flat from high to low frequencies. The transformer is driven so that even delicate sounds can be reproduced.
The parts also use PP film capacitors and low impedance chemiconductors, and metal foil resistors are used for resistors that affect sound quality. The power supply circuit is an all-discrete power supply, and employs a circuit that also controls high frequency noise. No high resistance or capacitors are used from input to output.
