Selecting Headphone Connection
provided three types of headphone output: 4-pins XLR for balanced,
4.4mm Balanced ,6.35mm for singled-end, we have optimized the headphone amplifier to perform
satisfactory for all outputs, user are free to use any headphone output according to their need without
worrying one is better than the other.
Single-ended Headphone Connection
HA-300 MK2 provides one set of 6.35mm headphone input,
the pin
definition of the headphone connector is
as illustrated.
Headphones terminated with 3.5mm connector will require a 3.5mm
to 6.35mm adapter in order to use
it with this headphone amplifier.

Balanced Headphone Connection
HA-300 MK2 provides one set of 4.4mm headphone input, the pin
definition of the headphone connector is as
illustrated.
Headphones terminated with 2.5mm connector will require a 2.5mm
to 4.4mm adapter in order to use
it with this headphone amplifier.
XLR Balance Headphone Connections
HA-300 MK2 provide one set of 4-pin XLR headphone input, the pin
definition of the XLR connector is as
illustrated.
Headphones terminated with dual XLR (3-pins), 4.4mm or 2.5mm
balanced headphone connectors will
require corresponding XLR4
adapter in order to use it with this headphone amplifier.
IMPEDANCE matched output
Headphones are currently available from 8
Ω
to 600
Ω
, in view of this wide range of impedance rating,
HA-300 MK2 provides three sets of impedance matched outputs (L:8~64
Ω
; M:65~250
Ω
; H: 251~600
Ω
) to
ensure the headphone amplifier can handle vast variety of headphones satisfactory.
We recommend users to start with the output setting that match the impedance rating of your
headphone.
It is technically safe to select any impedance setting for your headphone. You can try other impedance
setting without worrying causing any damage to your headphone.
