If you’re tracking more than one
musician at a time, or if everyone in the
group wants to listen to the playback,
you’re need a monitor distribution
system. A distribution system allows
everyone to listen in, and control the
volume of his or her own headphones.
The compact and exible HA400 can
power up to 4 pairs of headphones
and up to 4 independent volumes,
with outstanding audio quality – even
at maximum volume!

Altogether Now
You can use this super-compact stereo
headphone ampli er with practically any
headphones – four of them at the same time,
to be exact! Let up to 4 di erent people in your
studio listen to the main mix while recording,
and each listener can determine their own
preferred volume level using the dedicated
output level controls. The HA400 contains 4
high-power stereo ampli ers that maintain
the highest sonic quality even at maximum
volume levels. Ultra low-noise 4580 operational
ampli ers are employed for outstanding audio
performance – these are the same op amps
found in “full-size” audio equipment – plus,
a dedicated 12-Volt DC adapter is included.
