  • The RB-HD2 is a high performance 2-way stereo headphone distribution amplifier for driving up to 2 pairs of professional stereo headphones from a single stereo or mono input. A switch on the rear panel enables the distribution of a mono signal to all four outputs (i.e. both earpieces of a pair of stereo headphones) via the left channel input.

    The stereo/mono switch is located on the rear panel to prevent accidental knocking. The XLR-3 inputs are electronically balanced and can be wired unbalanced. There are two preset controls on the rear panel that adjust the level of the master input signal to the outputs.

    Each output is on a 1/4" stereo jack socket and is designed to drive 150 mW into 32 ohm to 600 ohm stereo headphones. The outputs are individually buffered with their own front panel volume control.

    A LED power indicator on the front panel displays the power supply connection.
