AMP HEAD II kit has dual stereo input mixing for mixing inputs together or directly plug in our Talkback Comp and can take large dual 24mm and 16mm with pull switch volume pots. Pull switch can be set to mute, dim or mono function.
Small size indestructable but extremely powerful and super low 0.001% THD stereo headphone amp kit with balanced inputs, volume control and buss connector to slave several AMP HEADs together. Also easy to add mono, mute and mix options.
Can drive dead short on headphone jack indefinitely.
Wattage into various headphone impedances with power rails @ +/-18vdc. Per channel wattage shown. Double mW for stereo wattage.
300R :- 380mW with the normal 470R summing resistors(or 500mW with 47R summing resistors if you are only going to run high impedance headphones)
150R :- 560mW with the normal 470R summing resistors
75R :- 685mW with the normal 470R summing resistors
35R :- 655mW with the normal 470R summing resistors
16R :- 475mW with the normal 470R summing resistors
8R :- 300mW with the normal 470R summing resistors
