OVERVIEW
GAIN SELECT SWITCH
The GAIN SELECT switch controls the overall gain level of the current output socket.
You may set it according to your desired level.
POWER SWITCH
The POWER SWITCH turns on or off the product. From the front view, turning it from left to right turns
on the HPA-01M.
* Remarks: It would take about 5 seconds to turn on the HPA-01M again when it is turned off.
GAIN KNOB
The GAIN KNOB controls the overall gain level. From the top view, turning it from left to right
increases the gain level, and vice versa.
* Remarks: The HPA-01M is zero negative feedback design that during its initial warm-up period,
it is possible to hear audible noise while controlling the gain. This is normal and absolutely fine for
the HPA-01M and its connected equipment. This audible noise will disappear shortly after.
LED DISPLAY
The LED DISPLAY turns on when the product is switched on. The red LED indicates low battery
capacity status. When the red LED turns on, it is recommended to recharge the battery. Within
10 minutes after the red LED is on, the HPA-01M shuts off automatically resulting from low battery.
CHARGER INPUT
The external battery recharger is connected to the HPA-01M via CHARGER INPUT.
Please use the supplied recharger only. The recharging process only starts when the HPA-01M’s
main power switch is turned off, and the recharging status is indicated by red color on the LED of the
recharger. The LED on the recharger turns red to green when the internal batteries are fully charged.

HEADPHONE OUTPUTS
The HPA-01M provides two different types of headphone driving methods. The HPA-01M‘s unique
feature lies within its current drive output socket where the connected headphone is driven by
current, rather than the conventional voltage driving method. Each output works simultaneously
but the current output’s gain level will be affected by the connected headphone’s impedance
in the voltage output socket.
SOURCE INPUT
There is a 3.5mm SOURCE INPUT jack to connect your source equipment. Connect your source, such
as a DAP or mobile phone, here using the supplied Cardas HPI cable, or any other 3.5 mm mini cable.
