SIX CHANNEL HEADPHONE AMPLIFIER

400 SERIES

The ART Model 406 Six Channel Headphone Amplifier
addresses the basic requirements for professional head­phone mixing. It’s a great processor for professional,
project and home studio applications. It has an output
and level control for each set of headphones, and a
stereo input for connecting the program source.

Headphone Mixing Made Simple.

The three basic requirements for professional headphone
mixing are; (1) an output for each set of headphones, (2)
a level control for each set of headphones, and (3) a
stereo input for connecting the program source (mixer,
CD player, tape deck. etc.). But there may be other
requirements. (4) A second stereo source may need to be
connected and mixed with the stereo program perhaps
added background tracks. (5) It may also be necessary
to insert a specific audio source into a specific head­phone channel possibly a vocalist wants to hear himself
or herself alone. (6) You may find it necessary to connect
a number of mono sources rather than one or two stereo
sources and have some degree of control over their rela­tive volumes perhaps the recordist or director needs to
address everyone. The trick is to make this headphone
mixer compact and simple to use.

Usage

a) Connect the AC cord to a grounded AC outlet.
b) Connect the STEREO INPUT (front) to the source,or

use two,shielded,mono (TS) cables to connect the
L and R MAIN (rear) Inputs to the source.

c) If needed, connect a second stereo source to the

L and R AUX input jacks (rear) using two shielded,
mono (TS) patch cables.

d) To connect a mono source,depress the MONO/STEREO

button on the front panel of the 406, then connect the
source to the L (mono) MAIN or AUX Input.

e) It is possible to connect up to four mono sources

with the 406 in MONO mode and the PAN control
acts as a relative volume level control between
signals connected to the R inputs versus the L
inputs. With the 406 in STEREO mode the PAN
control regulates L/R headphone balance as usual.

f) The INSERT jacks permit connecting a stereo source

directly and exclusively to any headphone channel.
Always plug a stereo (TRS) 1/4" jack into these inputs
so that sound can be present in both ears (these jacks
are not affected by the Mono/Stereo button). When
these jacks are in use,the MAIN and AUXILLIARY L and
R inputs are disconnected. Only the INSERT signal goes
to that corresponding OUT jack.

g) Connect stereo headphones to the OUT jacks on the

front panel and adjust the LEVEL controls as desired.
DO NOT plug a mono jack into any OUT jack as this
may damage the unit.
