6. Betjeningsvejledning

6.1. Input Gain Adjustment

Use the individual gain knobs for each input channel to set the appropriate recording level. Observe the LED level meters to ensure the signal is strong but does not clip (peak into the red).

6.2. Phantom Power (48V)

Press the '48V' button for the specific channel when using condenser microphones that require phantom power. Ensure the microphone is connected before activating phantom power to prevent damage.

6.3. Instrument Mode

When connecting a guitar or bass directly, press the 'INST' button for input channels 1 or 2. This optimizes the input impedance for passive instrument pickups.

6.4. Realtidsovervågning

The E4X4 Pre features a zero-latency hardware monitoring system. Press the 'MON' button on an input channel to hear its signal directly through your headphones or main monitors without any delay. This is crucial for performers during recording.

6.5. Headphone Outputs

The E4X4 Pre includes two independent headphone outputs, each with its own gain control. This allows for separate monitoring mixes or individual volume adjustments for two users. The powerful NFCA-LE headphone amp module ensures clear audio even with high-impedance headphones.
