GETTING TO KNOW THE X1HA-EPT AMP

The Input jack socket–(music symbol). To connect to your portable

player use a short length 3.5mm (1/8”mini) stereo jack plug cable.
Plug one end of this cable into this jack and the other end into

the

headphone or line output jack of your portable player.

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

plug in your high-end headphones. 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 600 ohm.
Consult your headphone manufacturer specification chart to deter

mine

your headphone impedance.

The Volume control -The volume control consists of a high

performance, tight tolerance dual-gang potentiometer.
Adjust the headphone volume level to your desired listening lev

el
by rotating the volume control knob clockwise to increase and counter
clockwise to decrease the volume level.

The Gain control switch–This is a push button switch located on the

Front panel. When it is depressed it will latch in the on positi

on providing

a gain boost of +10dB. This function is useful for adapting the

X1AH-EPT

input to different audio sources as well as adapting to differen

t headphone

impedances.

WELCOME

Congratulations on your purchase of the Xenos 1HA-EPT Enhanced
Performance Portable Headphone Amplifier (X1HA-EPT) with Texas
Instruments TPA 6120 output configuration.
The X1HA-EPT will provide you with exceptional audiophile performance
for your mid to high-end headphones when used with any playback
device that has a headphone or line output. The X1HA-EPT utilizes a
high performance Texas Instruments OPA2134 op amp as an input bu

ffer

and TPA6120 high performance headphone amp chip as the output dr

iver.

Please consult the product data sheet and specification sheet fo

r
Additional technical details.
The X1HA-EPT includes a built in Lithium Ion (Li-Ion) battery pack, the
package is supplied with a world AC voltage Li-Ion charger which doubles
as an AC adapter for the X1HA-EPT amplifier.

Take time to read through this user guide as it will provide you

with

valuable information to help you ensure that you get the very be

st
performance from your Xenos 1HA-EPT amplifier.
Thank you for choosing Xenos Audio Systems™from ATP Systems.

World AC voltage Li-Ion battery charger

When the gain switch is in the off position the amp input is cal

ibrated for

line level, when the gain switch is in the on position it is the

n calibrated

for headphone level input (like headphone jack of an MP3 player)

.

The Stereo Field Simulator control switch–This switch controls the

amplifier’s stereo channels. With this switch in the off position the amp
is in full stereo mode with left and right channels completely i

ndependent.

In the on position the SFS circuit is enabled.

The blue power LED–With the power turned on this LED has two

functions as follows: If the LED is on then battery level is goo

d; If the

LED is flashing at 1 second intervals the battery level is below

the

normal operating limit and the battery should be recharged.

The power switch–This is a small slide switch located on the rear

panel of the X1HA-EPT. Move this switch to the I position to switch
the amp on and to the 0 position to switch it off.

NOTE:

The Li-Ion
charger will continue to charge the internal Li-Ion battery irrespective
of the state of the power switch.

The DC charging jack–This jack socket is located on the rear panel

of the X1HA-EPT to the right of the battery charging symbol.

WARNING: Only use the provided Li-Ion charger to power the
X1HA-EPT amplifier. Any other AC adapter or charger may cause
irreversible damage to the Li-Ion battery pack and amplifier
electronics which will void the warranty.

CHARGING THE INTERNAL Li-Ion BATTERY

The X1HA-EPT is supplied standard with a built in, user replaceable
Li-Ion rechargeable battery pack. The Li-Ion battery is a 8.4V 2200mAH
type with a built in safety and protection circuit.
Under normal use, the battery will last about 16 hours on a full

charge
after which it must be recharged using ONLY the provided AC Li-Ion
charger. The Li-Ion charger will recharge the battery fully in about 4
hours. The Li-Ion charger has an LED indicator which glows red while
the battery is being charged and glows green once full charge ha

s been

reached. The DC plug of the charger is plugged into the DC charg

ing
jack on the rear of the X1HA-EPT and the charger is then plugged into
the wall AC outlet.
The Li-Ion charger will enable you to charge the battery while at
the same time allowing you to use the amplifier, in other words

it will also

power the amplifier. While using the charger in this mode the LE

D on the
charger will glow red even after the Li-Ion battery has reached
full charge. There is no concern here as the charger will automa

tically
stop charging the battery once it has reached it’s fully charged status.
When the battery is fully charged and the power switch on the
X1HA-EPT is turned off the LED on the Li-Ion charger will turn to green
indicating that the internal Li-Ion battery pack is fully charged.
The Li-Ion battery pack will
eventually wear out and will
need to be replaced.
ATP Systems provides
replacement Li-Ion battery
pack kits including detailed
instructions for replacing the
battery. Alternatively you may
choose to return your
X1HA-EPT to ATP Systems
for battery service. Please see
our web site for details.

ADJUSTING SOUND LEVELS

Adjusting the volume level.

The volume control on the X1HA-EPT adjusts the signal level to the
output amplifier stage that drives the headphones. Before poweri

ng
up the X1HA-EPT, set the volume level on your playback device to
about 50% and start playing a music track. Turn on the X1HA-EPT,
place your head-phones on, now adjust the X1HA-EPT volume control
to a desired level. If need be increase the volume setting on yo

ur play

­back device and adjust the volume setting on the X1HA-EPT 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 any discomfort is felt in your ears.

Adjusting equalisation (tone).

The X1HA-EPT 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.

Adjusting the Gain setting–Depending on the signal source you are

using the gain control will provide the ability to adjust the X1HA-

EPT
overall gain to the most desirable level.
If you are connecting to a DVD / CD / AV receiver line output th

en setting
the gain switch on the X1HA-EPT to the off position will provide the most
suitable setting with medium impedance headphones of 32 ohm to
120 ohm. If your headphone impedance is 300 to 600 ohm then
depending on the headphone sensitivity it may be more appropriat

e to
set the gain switch to the on position.
If you are connecting the X1HA-EPT to the headphone jack of an audio
playback device then the most appropriate setting for the gain c

ontrol

switch would be the on position. This will provide a +10dB boost

in

overall amplifier gain and also provide more than adequate drive

levels

for headphone impedance loads from 16 ohm through to 600 ohms.

Stereo Field Simulator control–With the SFS switch in the on position,

the X1HA-EPT simulates a live stereo listening environment such as that
presented by stereo speakers placed in a room about 4 meters apa

rt and

the listener positioned in the centre about 5 meters from the sp

eakers.
The SFS circuit essentially eliminates the “super-stereo”effect that is
evident is a full stereo headphone listening mode. It effectivel

y simulates

a stereo room listening environment providing you with a more re

alistic

stereo field. The SFS works by feeding a portion of the left cha

nnel signal

into the right channel and vice versa through a frequency and de

lay profile

filter which has the effect of simulating the stereo listening r

oom field.
