• LO Tone Control: Adjusts the low-frequency response of the mixed audio.
• MASTER VOLUME-knap: Styrer den overordnede udgangsvolumen for amplivligere.
• LIMITER LED: Illuminates when the internal limiter is active, indicating that the output signal is being compressed to prevent distortion.
• SIGNAL LED: Illuminates when an audio signal is present at the output.
• Hovedtelefonstik: 3.5mm stereo output for monitoring the mixed audio signal.

5. Opsætning

5.1 Placering og ventilation

Placer amplifier on a stable, flat surface. Ensure there is at least 10 cm (4 inches) of clear space around all sides of the unit for proper ventilation. Do not place the amplifier near heat sources or in direct sunlight.

5.2 Connecting Audio Inputs

• Mikrofoner: Connect your microphones to the appropriate input jacks on the rear panel (not visible in the provided image, but standard for mixer amplifiers). Ensure correct cable types (e.g., XLR or TRS) are used.
• Background Music (BGM): Connect your audio source (e.g., CD player, media player) to the BGM input. Use appropriate RCA or TRS cables.

5.3 Connecting Audio Outputs (Speakers)

Tilslut dine højttalere til amplifier's output terminals on the rear panel. Ensure the speaker impedance matches the amplifier's output impedance (typically 4 Ohm or 8 Ohm, or 70V/100V line for public address systems). Incorrect impedance can damage the amplivligere eller højttalere.

5.4 Strømtilslutning

After all audio connections are made, connect the supplied power cord to the amplifier's power inlet and then to a suitable AC power outlet. Ensure the power outlet is grounded.

6. Betjeningsvejledning

6.1 Tænd/sluk

• For at tænde skal du trykke på MAGT button. The power indicator (if present, typically on the front panel) will illuminate.
• For at slukke skal du trykke på MAGT knappen igen.

6.2 Justering af inputniveauer

• Indstil alle Mic 1-4 og BGM volume knobs to their minimum position (fully counter-clockwise) before starting.
• Gradually increase the volume knob for the desired microphone or BGM source while speaking into the microphone or playing music.
• Adjust each input level until the SIGNAL LED flickers consistently during normal operation, but the BEGRÆNSER LED rarely illuminates.

6.3 Tone Control Adjustment

• Brug HI control to adjust the treble frequencies. Turn clockwise for more brightness, counter-clockwise for a softer sound.
• Brug LO control to adjust the bass frequencies. Turn clockwise for more bass, counter-clockwise for less bass.
• Adjust these controls to suit your preference and the acoustics of the room.

6.4 Hovedlydstyrkekontrol

Once individual input levels are set, use the large MASTER VOLUME knob to control the overall output volume of the amplifier. Adjust this to the desired listening level for your audience.

6.5 Hovedtelefonmonitorering

Plug 3.5mm headphones into the headphone jack to monitor the mixed audio signal without affecting the main output. The headphone volume is typically linked to the Master Volume or has its own dedicated control (not explicitly shown but common).
