To connect the ART Project Series Low Noise Precision Phono Preamp to your audio system, follow these steps:
1. AC Power Hookup:
- The Precision Phono-PS comes with a universal external power supply that operates at 100 to 240V AC ~ 50/60 Hz.
- Use the adapter that came with the Precision Phono-PS. If it is lost or damaged, contact ART Customer Service for a replacement.
- Connect the power supply to the unit's labeled 12V DC input. Ensure that the output plug is securely plugged into the rear of the Precision Phono-PS and that the adapter is firmly plugged into an electrical outlet.
- Never operate the Precision Phono-PS or power adapter in the rain or wet locations.
- If the turntable has a separate ground wire, attach it to the Ground terminal on the Precision Phono Pre to reduce hum.
2. Audio Connections:
- Connect the RCA outputs of the Precision Phono Preamp to the appropriate inputs on your mixer or stereo receiver. Use RCA cables.
- If your mixer does not have RCA inputs, you may need a stereo RCA to dual mono ¼-inch male cable to connect to the mixer's line inputs.
3. Selecting the Cartridge Setting:
- Use the MC/MM switch on the Precision Phono Preamp to select the correct mode for your cartridge.
- If you have a high output MC cartridge that requires a 47k load, choose MM mode.
- If using MC mode, select the correct load (100 or 24 Ohms) using the Load switch. There will be a slight difference in sound between the two settings.
- Start with the manufacturer's recommended load. If unsure, select the 100 Ohm setting. If the high end is exaggerated, the 24 Ohm setting will flatten the response by dampening the cartridge resonance.
4. Low Cut Filter:
- The Filter switch on the Precision Phono Preamp adds a filter for removing turntable rumble or other low-frequency noise.
- When in the Low-Cut position, the filter rolls off deep bass to eliminate turntable rumble and "skipping" caused by heavy foot traffic areas.
