4. Arahan Operasi

4.1. Menghidupkan/Mematikan

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.

4.2. Adjusting Headphone Levels

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

The Mono 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.

4.4. Monitor Level and Mute

The Tahap Monitor knob controls the overall output level of the balanced monitor/thru outputs on the rear panel. The Pantau Bisu button silences these outputs without affecting the headphone outputs. This is useful for quickly cutting monitor sound while maintaining headphone mixes.
