Glensound HA6+ - Six Stereo Headphone Amplifiers

The HA6+ has 2 x XLR inputs that are used as the primary programme audio input, and 2 x XLR inputs that are used for the secondary aux audio input. These can be stereo, or, if a mono input, can be switched to appear on both sides of the headphones. There are left and right primary input gain controls on the rear panel, and they are on recessed screw terminals.

On the front panel there is a source control for each headphone output that allows a mix between the programme and aux input. Full left is programme only, full right is aux only, and anywhere in between is a variable mix.

Each of the six headphone amplifiers has its own volume level pot. There is also a master volume pot that controls the overall level of all amplifiers. This can be defeated via a rear panel dip switch. Each of the six headphone outputs are available via front panel 6.35mm jack sockets, and in parallel on rear panel XLR connectors.

Rear panel inputs and outputs are electronically balanced on XLRs and can accommodate unbalanced connections if required.

Power is provided by an internal switch mode power supply, with a wide input range. There is also an input for external 12v DC power. The 12v DC input can be connected to the optional Signature PS1external DC Master Power Station, for situations where a redundant power supply is desirable.

A bright front panel LED indicates that the unit is operational.
