ZO's Volume Control
ZO is designed to work with a wide range of headphones
without the need for multiple gain modes. Because ZO
doesn't utilize gain modes, its volume control includes
both attenuation and gain levels:
Volume
Levels
Attenuation/Gain
0 to 174
Attenuation (0.5 dB steps)
175 to 210
Gain (0.5 dB steps)
To get the best sound quality, set your source's volume
between 75-100% (unless it's a fixed output), and then use
ZO to attenuate or amplify the audio signal. If you're using
a sensitive headphone or IEM (> 100 dB/mW), you will
most likely need to attenuate the output (volume levels <
174). If you're using a high impedance headphone or one
with less sensitivity, you will probably need to amplify the
output (volume levels > 175).
Applications
Did you know ZO can make more than just your
headphones sound better? Try it in the car, with your
gaming gear, or with your computer speakers!
Troubleshooting
Hearing hiss/noise
• If using a smartphone, noise may be from radio wave
interference. Change the device's communication mode
to one that blocks communication signals, such as
airplane mode.
• Plug your headphones in to the ZO, but do not connect
your audio source. Turn ZO on. If no noise is heard, then
the player or the track could be generating the noise.
• Incorrect volume level settings may result in audible
noise levels if you're using high sensitivity headphones
or IEMs. Please review the section ZO's Volume Control
above.
• If charging, use a USB wall adapter instead of a
computer.
Undesirable Sound Quality
• Make sure the battery is fully charged.
• Turn off all sound enhancements such as EQ, virtual
surround sound/3D effects or noise cancelation.
Attenuation/
Gain Amount
• Improper setup of volume levels and SVT settings may
cause clipping or other audible distortion. Please visit
-87.15 to -0.15 dB
www.digizoid.com/support for more information.
0.35 to 17.85 dB
• Highly compressed tracks may already include some
amount of clipping and distortion. This may become
more apparent during playback with ZO. To learn more,
