INTRODUCTION
Thank you for choosing Phonic, your sound partner
and world famous audio equipment manufacturer.
The A6200 SupermeDI is a 6-channel active direct
box which allows you to connect a high-impedance,
unbalanced source, such as your electrical guitar
or bass, to the mic input channel on your mixer. In
doing so, the A6200 SupermeDI easily eliminates the
annoying humming or ground looping that results from
using a microphone to pick up the signal in front of
the guitar amp. Need not to worry about if you have
the appropriate connectors, the A6200 SupermeDI
can automatically turn the unbalanced signal into a
balanced one before connecting it to your console.
Review this manual carefully to learn more about the
features and operating procedures for the A6200.
Should future questions arise, please refer back to
this manual.

INITIAL SETUP
The following is the recommended initial setup for your
A6200.
For channel 1 to channel 6
1 Set the dB level at –40 (dB)
2 Set the impedance level at 400K (ohms)
3 Play the connected instrument to test the output:
A. If the sound output is not loud enough,
adjust the dB level between –20 and 0 (dB)
until the output reaches a suitable volume.
B. If the sound output is not clear, adjust the
impedance level between 22K and 2.2K
(ohms) until the output is satisfactory.
4 If humming appears in the sound output, press the
GND/LIFT button.
5 If the connected instrument is a bass guitar, press
the HI-CUT button to remove frequencies
above 8KHz in the output.
6 If the input signal needs to be sent to two mixers,
press the CH-SPLITTER button to duplicate
the signal. (Please refer to the application for more
information.)
TYPICAL CONNECTING LEADS
On the following page typical connecting leads
have been sorted into seven categories: BALANCED,
UNBALANCED, INSERT CORD, BALANCED
Y-CORD, HEADPHONE SPLITTER, and
UNBALANCED Y-CORD.
The wiring for each of these connectors is detailed in
each category; please refer to the proper group for
your desired application.
All input and output connectors (XLR-male out, 1/4”
phone jack SPL/OUT & OUT, XLR-female input) are
balanced for the A6200 SupremeDI.

FRONTAL PANEL DESCRIPTION
The six channels on the A6200 all with the same
functions and connections.
1 OUTPUT connector
The balanced output accepts an XLR-F connector, and
sends a processed signal to the mixing console.
2 OUTPUT SIGNAL indicator
This green LED will turn on when a signal greater
than –25dB is present in the signal path.
3 CLIP indicator
This red LED will turn on when a signal of 15dB is
present, as a reminder against possible overload.
4 INPUT IMPEDANCE selector
This selector allows the unit to match the impedance of
the input at 2.2 K, 22 K, or 400 K ohms.
5 GAIN switch
This switch increases the operating range of the input
signal to 0 dB, -20 dB or -40 dB.
6 GND LIFT button
Push this button to separate the ground of the INPUT
from that of the OUTPUT, and reduce hum from ground
loops.
7HI-CUT 8kHz
Push this button to filter out frequencies above 8kHz
in the signalt.
8 SPLITTER switch
Push this switch to duplicate the processed signal from
one channel to another (e.g. from CH1 to CH2). The
SIGNAL and CLIP indicators will remain in the service
of channels 2, 4, and 6.
9 POWER button
Push this button to turn on the SUPREME DI.
FRONTAL PANEL DESCRIPTION

PHONIC CORPORATIONA6200 USER’S MANUALPage 8
CONNECTING PANEL DESCRIPTION
All six channels on the A6200 contain the same
connections.
10 AUDIO INPUT
Each input has one combo connector that accepts either
an XLR-Male connector or a 1/4" TRS phone jack.
11 OUTPUT & SPL/OUT connectors
A. During normal (non-split) operation: Each
channel sends its independent output signals through
this balanced 1/4” phone jack.
B. When SPLITTER is activated for a channel pair (e.g.
CH1 & CH2): The INPUT signal for the even-numbered
channel (CH2) are disabled, and its SPL/OUT signals
duplicate the OUTPUT signals of the odd-numbered
channel (CH1).
12 AC Power cable socket and fuse holder
Connect the supplied AC power cord to this socket, then
insert the plug into a wall-socket of suitable voltage. The
required AC voltage is printed next to the socket. A blown
fuse may only be replaced by a fuse of identical type and
rating as those listed alongside the fuse holder.
CONNECTING PANEL DESCRIPTION

A6200 USER’S MANUALPHONIC CORPORATION Page 9
APPLICATION
With A6200, you may directly connect the guitar output to the mic input of a mixer, or convert any unbalanced signal to
a balanced signal for long distance cabling.
TAPPING SIGNAL FROM A GUITAR
The SupermeDI can send the output from a guitar directly as input to both the the mixer (for mixing) and the guitar amp
(for monitoring).
APPLICATION

PHONIC CORPORATIONA6200 USER’S MANUALPage 10
CONVERTING UNBALANCED TO BALANCED OUTPUT
The SupermeDI can convert unbalanced output to balanced output before the signal is connected to the mixer’s mic
input. When plugging in stereo signals, set the pan controls for the left and right input channels respectively.
APPLICATION

A6200 USER’S MANUALPHONIC CORPORATION Page 11
DUPLICATING SIGNAL TO TWO DIFFERENT DESTINATION
BY USING THE SPLITTER BUTTON
The SupermeDI can duplicate a signal from an odd numbered channel to an even numbered channel (e.g. CH1 to
CH2). The duplicate signals can be routed to both a stage mixer and a FOH mixer to ensure an identical source signal
for both mixers.
