Main Features:
- Three Channel or Four Channel compatible
architecture design.
- A total of 8 gold-plated DIP sockets for OPA Ps
and Buffers allowing for opamp or buffer rolling.
- 3 Gain settings for impedance matching.
- Bass boost to enhance bass performance.
- Powered by dual 9V batteries, or the P5 power
supply.
- High output power, 660mW+660mW into 32Ω when
powered by batteries, or 1000mW+1000mW into
32Ohm when powered by the P5 power supply.
- CNC engraved aluminum housing, which can be
opened with just one screw.
Caution:
To protect your hearing, please follow the operation
guide and do not listen at extremely high volume
levels. Extended high volume listening can lead to
permanent hearing loss.

Inserting and Charging the Battery:
Before inserting the 9V batteries, check the position
of positive and negative terminals. ake sure the
batteries are being placed in correct direction.
The P5 power supply can charge 9V NiMH batteries
only. When using 9V Li-ion or other 9V non Ni H
batteries in the P5, the power supply must be
disconnected to avoid harm to the batteries or the
power supply. Failing to follow these directions
could cause fire and or the batteries to explode.
There is not charge lamp on the P5 or the P5 power
supply. The batteries are being charge once the P5
power supply is connected. The batteries will be
fully charged after 8~16 hours. Since the charge
current is small and limited, you can leave the P5
power supply plugged with no over-charging
concerns.
OPAMP and Buffer Rolling
Before opening the housing to change OPA Ps or
buffers, make sure the P5 is turned off. OPA Ps
and Buffers can be damaged by static electricity. It is
better to change OPA Ps and buffers in a static-free
environment. Also, before inserting the OPA Ps in
the sockets, check to make sure if it is a single or dual
OPA P, then place it to the right position.
Direction of Inserting the OPAMP and Buffer:
In the following drawing, the first pin of the OPA Ps,

Buffers, or dummy adapters is indicated. In the above
picture, there is a black hole on each amplifier or
buffer socket, which is where the first pin should go.
*Be aware that inserting the OPA P or Buffer in a
wrong direction may cause damage, which is not
covered by warranty.
DC Detector:
There is a blue lamp inside the housing, right after the
output socket, that is the DC detector. You can see
the blue lamp lit when DC is detected in situations
such as, OPA P or buffer is inserted in an incorrect
direction, inserted in a wrong position, or defective.
Sometimes, right after the P5 is turned on and before
a steady state condition is reached, the blue lamp will
light in a flash, then goes off. This is normal.
Warranty:
iBasso P5 is warranted to be free from malfunctions
and defects in both materials and workmanship for a
period of one year from date of purchase, excluding
OPA Ps, and the accessories. Buyer must retain the
warranty card, which will be requested at the time of
warranty repair.
This warranty does not apply when failure is due to
accident, alteration, water damage, misuse, use with
incompatible accessories or attachments or failure to
follow operating instructions.
At iBasso we always do our utmost to take care of
your needs. For further product and warranty
