5. Installation et connexions

Follow these steps to connect your Palmer Monicon L to your audio system:

5.1 Connexion d'alimentation

1. Connect the included DC 15V 200mA power adapter to the "DC 15V 200mA" input on the rear panel of the Monicon L.
2. Plug the power adapter into a suitable wall outlet. The LED indicators on the front panel will illuminate.

5.2 Connexions d'entrée audio

The Monicon L offers two distinct stereo input options:

1. Main Stereo Input (Input 1): Use balanced XLR or 1/4" TRS cables to connect your primary audio source (e.g., audio interface, mixer output) to the "STEREO INPUT L/R" combo sockets on the rear panel.
2. Auxiliary Input (Input 2): For secondary audio sources (e.g., computer, media player), use RCA cables to the "AUX INPUT L/R" RCA connectors or a 3.5 mm TRS cable to the "AUX INPUT" 3.5mm jack.

5.3 Connexions de sortie audio

The Monicon L provides multiple output options for your monitoring setup:

1. Monitor Speakers (Output 1 & 2): Connect your self-powered monitor speakers using balanced XLR cables to the "OUTPUT 1 L/R" and/or "OUTPUT 2 L/R" XLR connectors. You can connect up to two pairs of monitors.
2. Subwoofer (Mono Sum): If you use a subwoofer, connect it to the "MONO SUM" XLR output. This output provides a summed mono signal of the selected stereo input.
3. Casque audio : Plug your headphones into the 6.35 mm (1/4") TRS "HEADPHONES" jack on the front panel.

6. Fonctionnement

This section details the functions of each control on your Monicon L.

6.1 Contrôle du volume

• VOLUME STÉRÉO : Rotate this large knob clockwise to increase the volume of the selected stereo output, and counter-clockwise to decrease it. This is the primary volume control for your monitor speakers.
• VOLUME AUXILIAIRE : Adjusts the input level for the auxiliary input source. This allows you to balance the volume of your auxiliary device before it reaches the main stereo volume control.
• ÉCOUTEURS: Controls the listening volume for headphones connected to the front panel jack.

6.2 Sélection d'entrée

• INPUT SELECTION (1/2): Press the "1" button to select the main stereo input (XLR/TRS combo sockets). Press the "2" button to select the auxiliary input (RCA/3.5mm TRS). Only one input can be active at a time.

6.3 Sélection de sortie

• OUTPUT SELECTION (1/2): Press the "1" button to activate the first pair of monitor outputs (OUTPUT 1 L/R). Press the "2" button to activate the second pair of monitor outputs (OUTPUT 2 L/R). You can activate both outputs simultaneously to listen through both speaker pairs.

6.4 Fonctions de surveillance

• STEREO MONO: Press this button to sum the stereo signal into a mono signal. This is useful for checking phase compatibility and how your mix translates to mono playback systems.
• MUET: Press this button to instantly silence all active outputs. Press it again to restore the audio.
• PFL STEREO / PFL AUX: These buttons enable Pre-Fader Listen for the respective inputs. When activated, the selected input signal is routed directly to the headphone output, bypassing the main STEREO VOLUME control. This allows you to monitor an input source without affecting the main speaker output.

7. Maintenance et entretien

• Nettoyage: Disconnect the power adapter before cleaning. Use a soft, dry cloth to wipe the surface of the unit. Do not use liquid cleaners, aerosols, or solvents.
• Environnement: Keep the Monicon L away from direct sunlight, excessive heat, moisture, and dust.
• Stockage: Si vous devez entreposer l'appareil pendant une période prolongée, débranchez-le de l'alimentation électrique et rangez-le dans un endroit frais et sec.
