player use the included 2ft 3.5mm stereo jack plug cable. Plug o

ne end

of this cable into this jack and the other end into the headphon

e or

line output jack of your portable player.

The output jack socket–(headphone symbol). This is where you

plug in your

IEM’s. This socket accepts a standard 3.5mm (1/8”mini)
stereo jack headphone plug. You may connect headphone sets with
impedance ranging from 16 ohm to 300 ohm. Consult your IEM
manufacturer specification chart to determine your headphone imp

edance.

The X0HA-REP is not recommended for

IEM’swith impedance

exceeding 300 ohm.

The volume control and power switch-The volume control has an

integral power switch, when rotated to the “Off”position the power is
turned off. To turn on the X0HA-REP simply rotate the volume control
clockwise, you will hear a click and if the battery is at the co

rrect voltage
level the blue power LED will light up.
Adjust the IEM volume level to your desired listening level
by rotating the volume control knob clockwise to increase and counter
clockwise to decrease the volume level.

NOTE:

It is normal for the X0HA-REP to become slightly warm when
using it with An AC adapter. Do not place the X0HA-R near a heat source
or in a small confined space when operating it using an AC adapt

er.

ADJUSTING SOUND LEVELS

Adjusting the volume level.

The volume control on the X0HA-REP adjusts the signal level to the
output amplifier stage that drives the

IEM’s. Before powering
up the X0HA-REP, set the volume level on your playback device to
about 50% and start playing a music track. Turn on the X0HA-REP,
insert your

IEM’s, now adjust the X0HA-REP volume setting to a
desired level. If need be increase the volume setting on your play­back device and adjust the volume setting on the X0HA-REP
accordingly to reach your desired listening level.

WARNING: Extended exposure to high sound levels can cause
permanent hearing damage. Reduce volume level or discontinue
use if discomfort or pain is felt in your ears.

Adjusting equalisation (tone).

The X0HA-REP has a flat frequency response, it does not have
any internal circuitry that adjusts or modifies the equalisation

levels.
However, most portable playback devices do include multiple
pre-set equalisation levels with some higher end devices also

incorpor

-

ating

custom equalisation controls. You may use the equalisation

controls included with your playback device to adjust the playba

ck

tone to suit your listening pleasure.
