Gain Selection
The HA-2(SE) has two gain levels. The low gain (L) level is
intended for use with high sensitivity headphones and In-Ear
Monitors (IEMs). The high gain (H) level can be used for
other headphones if you feel that the volume is too low in low
gain level even when the Power/Volume Knob has been
rotated to the maximum volume position.
Please follow this procedure to safely change gain level:
•
Turn off the unit first.
•
Flip the Gain Switch to the high gain (H) position.
•
Turn on the unit and gradually adjust the volume.
•
Remember to reset the Gain Switch to low gain (L)
position if you switch to a new pair of headphones.
For certain IEMs, if at the low gain setting the volume is still
too loud, you can adjust the volume control on your playback
device. For Apple products connected to the USB A port or
playback software that supports USB volume, the HA-2(SE)’s
internal 32-bit digital volume control will be used so there will
be no loss of resolution or truncation of audio samples.
CAUTION:
Changing the gain level on the fly may result
in a sudden increase of the output power, and may damage
your headphones and hearing.
Bass Boost
If you like to listen to music with a strong bass effect, you may
turn on the Bass Boost function of the unit. To do so, flip the
Bass Boost switch so a green bar is shown.
