Broadcast Stereo Headphone Amplifier - 

The Signature HA1+ is a broadcast specification headphone amplifier, designed to operate in a mono or a stereo mode. It has 2x XLR inputs with separate gain controls on the front panel. There is also a secondary, mono XLR cue input. The headphone output is available via a front panel 6.35mm socket, and in parallel on a rear panel XLR connection. The HA1+ uses Glensound’s propriety CAN headphone system. This allows multi impedance headphones to be used, with the same perceptual level in the headphones when the volume control is kept in a fixed position. Stereo or mono connections can also be made to the headphone sockets, including mono earpieces. There is a remote connection available via an RJ45 or a 9 pin D-type connection. 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 and an input for external 12V DC power.
