4.1. പവർ ഓൺ/ഓഫ്
Once all connections are made, ensure the master Monitor Level knob is turned down before powering on. The HP4 does not have a dedicated power switch on the unit itself; it powers on when connected to the power supply and off when disconnected. Some power supplies may include an inline switch.

Each of the four headphone outputs has an independent volume knob. Rotate the knob clockwise to increase the volume and counter-clockwise to decrease it. Advise users to start with low volume and gradually increase to a comfortable listening level.
4.3. Using the Mono Switch
ദി മോണോ switch on the front panel sums the stereo input signal to mono. This can be useful for checking phase compatibility or for monitoring a mono source across both ears of the headphones.
