GS-HA009 - IFB Earpiece and Headphone Driver

The GS-HA009 is suitable for driving a wide range of impedance headphones and earpieces from 8 to 2000 Ohms.

It has a small inbuilt loudspeaker which can be used for simple monitoring and is disconnected when a headphone jack is inserted.

The GS-HA009 is a mono headphone amplifier capable of driving both mono & stereo headphones & earpieces. A limiter is built in to protect the user from a sudden loud input level. The limiter can be switched into & out of the circuit.

The audio input is balanced on an XLR (a loop through XLR is provided for daisy chaining several devices together). A 20dB gain switch is provided to boost the input level if required.

The design of the GS-HA009 is very low current and as such it provides a very long battery life.
