Operation Manual

Mute

Pressing the MUTE button on the remote control will disable audio output for the HA-1, and the Front Panel Display

will show the Mute icon. You can cancel Mute by rotating the Volume Knob, pressing the VOLUME +/- button on the

remote control, or by pressing the MUTE button again.

Remote:

For those who use the HA-1 as both a headphone amplifier and a pre-amplifier, it is possible to assign the MUTE

button to the Pre-amplifier Output only. This way the user can mute the large speakers with the MUTE button while

still being able to listen to the headphones. Please refer to the Mute Operation section in the Advanced Operations

chapter of this manual for details.

Playback Controls

When the active input source is the USB DAC Audio Input, Mobile USB Audio Input, or Bluetooth Audio Input, the

PLAY / PAUSE, PREV, and NEXT buttons on the remote control are passed on to the computer or mobile device. This

function allows you to control playback by starting, stopping, and skipping to the next or previous track. Not all software

or devices support this function. This function does not control devices connected via the Coaxial, Optical, AES/EBU,

RCA Stereo, or XLR Balanced Audio Inputs.
