Connection Cables

Take care of your cables, always holding them by the connectors and avoiding knots and twists when
coiling them: This gives the advantage of increasing their life and reliability. Periodically check your
cables. A great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely
by using unsuitable or faulty cables.

For these applications the unit provides 1/4" TRS and XLR connectors to easily interface with most
professional audio devices. Follow the configuration examples below for your particular connection.

Maintenance

The DAP PMM-401 requires almost no maintenance. However, you should keep the unit clean.
Disconnect the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in
liquid. Do not use alcohol or solvents.
Keep connections clean. Disconnect electric power, and then wipe the audio connections with a damp
cloth. Make sure connections are thoroughly dry before linking equipment or supplying electric power.
