The HC 6 features six independent stereo headphone amplifiers, each of which has two headphone outputs, one on the front panel and one on the rear. Depending on the installation, this setup provides greater flexibility.
The HC 6 provides master stereo 1/4" TRS inputs which can drive any or all of the 6 stereo headphone amplifiers. A mono switch is provided on the front panel to drive both channels of all six amplifiers from a common mono source. Six individual unbalanced stereo inputs are available to drive any individual amplifier from a separate stereo source. These inputs can be converted to mono balanced inputs through internal jumpers if required.
The HC 6 is capable of delivering up to 450 mW per channel into headphones with rated impedance between 32-600 ohms. The precise amount of power depends on the exact impedance of the headphone in use and the number of headphones connected to the unit. Under most conditions, the amplifier produces sound pressure levels in excess of 120dB. This level is more than adequate for most listeners.
