- 1 - Issue 1.1
The ultimate in balanced and single ended headphone listening.
The MX HPA is a very high performance fully balanced headphone amplifier Class “A”
in a beautifully designed and executed casework.
unit features two inputs, balanced and single ended. These are separate and an The
input select switch allows choice between separate balanced and single-ended sources.
These inputs accept normal line-level signals of 300mV nominal (suitable for 30mV-
>3V) from a wide range of equipment.
Gain switching is provided to allow boost for higher impedance headphones, so the
unit is compatible with all dynamic headphones regardless of impedance. It is
recommended to use the LOW setting for headphones of 200 ohms or less; the HIGH
setting for headphones over 200 ohms or particularly insensitive headphones.
The front panel XLR/JACK sockets are dual purpose; it is possible to use either one or
two - terminated headphones; pairs of standard 6.25mm ¼” stereo Jack
or
a
single
pair
of headphones, terminated in two three-pin male XLR plugs.
