Congratulations on your purchase of the CARVIN
H400
Four
Channel Headphone Amp. Your unit has been engineered and
made in the U.S.A. using only high quality electronic components
and uncompromising workmanship.
The
H400
will drive a total of eight pairs of headphones to their
maximum output with excellent clarity. The
H400
features four
independent output channels each with it’s own mix of 3 stereo
sources: INPUT A, INPUT B and the AUX IN for that channel.
When using the unit in MONO, a total of 4 main inputs plus 2 aux
inputs for each channel are available. The signal routing flexibility
of the
H400
makes it useful as a distribution amp for installation
applications.
Use caution with the
H400
. It is capable of high levels which may
cause hearing damage.
