THIS LISTING IS FOR IS FOR AN ALCTRON HP400 - 4 WAY HEADPHONE SPLITTER AMP.
I
Introduction:
Alctron HP400 is a professional 4-channel multifunctional Headphone Amplifier. It features the level indicator of the input/output volume, in order that you can control the amplifier to work in an ideal range. And each channel has Left Mute and Right Mute, AUX Input, L/R parallel, bass equalization, treble equalization, volume
control, output level indicator and parallel headphone output on the front panel and the rear panel. It also sets 1/4" Jack stereo input and L/R Main channel (1/4" jack or XLR) input/output. So it can be many flexible combination during the real application. It is suitable for professional recording, ratio and television studios,
as well as CD/digital sound production.
