IN STOCK 2 (more can be backordered)
Small, but nonetheless very well developed the HP4 headphone amp is designed for home studios, listening labs and more. The 15 sec tour: L & R inputs on back, 4 x 1/4″ stereo headphone outputs with individual volume pots on front, PLUS a ‘monitor level’ pot on the front. This can be used for control room monitors. Very handy.
L & R outputs on rear can feed studio monitors, (mono mute switches on front) or to loop through to more HP4 units.
