3. Zapojte druhý konec napájecího kabelu do vhodné zásuvky střídavého proudu.

5.3 Audio připojení

Connect your audio sources to the appropriate input jacks on the rear panel:

• Line-Level Devices (Mixers, Audio Interfaces): Use an XLR or 1/4" TRS cable to connect to the LINE IN (A) or MIC/LINE IN (B) jacks.
• Mikrofony: Use an XLR cable to connect to the MIC/LINE IN (B) jack. If the microphone signal is weak, engage the MIC BOOST switch.
• Stereo Playback Devices (Smartphones, Laptops): Use a 3.5 mm TRS cable to connect to the STEREO AUX IN (C) jack.

To connect multiple CP12 loudspeakers or send the audio to another device, use an XLR cable from the MIX OUT (POST GAIN) jack to the input of the next device.

6. Provoz

6.1 Zapnutí a vypnutí

1. Ensure all audio sources are connected and their volume levels are turned down.
2. Flip the POWER ON/OFF switch to the ON position. The POWER indicator will illuminate.
3. When powering off, first turn down the volume of all connected audio sources, then flip the POWER ON/OFF switch to the OFF position.

6.2 Adjusting Input Gain

Use the GAIN A and GAIN B rotary controls to set the input level for each channel. Start with the gain knobs fully counter-clockwise (OFF) and slowly increase them until the desired volume is achieved without the LIMITER indicator flashing excessively. Occasional flashes are acceptable, but constant illumination indicates signal clipping and potential distortion.

6.3 Selecting Contour Settings

The CONTOUR switch allows you to quickly optimize the loudspeaker's frequency response for different applications:

• VÝCHOZÍ: Provides a flat, uncolored sound, suitable for general use or when external equalization is preferred.
• EXT SUB: Engages a high-pass filter, removing low frequencies from the CP12 output, ideal when paired with an external subwoofer.
• DANCE: Boosts low and high frequencies for a more impactful sound, suitable for music playback in entertainment settings.
• DANCE EXT SUB: Combines the Dance contour with the high-pass filter for use with an external subwoofer in music playback scenarios.
• MLUVENÝ PROJEV: Optimizes the frequency response for maximum vocal intelligibility, reducing muddiness and enhancing clarity.
• MONITOR PODLAHY: Adjusts the frequency response to minimize feedback and provide clear sound when the speaker is used as a stage monitor.

Experiment with these settings to find the best sound for your specific application and environment.
