Connecting the DDP-1 to Your Audio System
First, turn your power amp off. Do not connect the DDP-1's power supply until all audio connections have been made.
Power Supply Connection: Stock Power Supply
To connect the stock AC power supply that comes with the DDP-1, connect the power supply's cable to the coaxial AC
power input on the upper right corner of the back of the DDP-1. Do not plug the power supply into the AC wall socket until
you have finished all audio connections. Do not connect the stock power supply if you are using the PS-5 Power Station.
Power Supply Connection: Optional PS-5 Power Station
If you are using the optional PS-5 Power Station power supply, plug the cable that comes with the power supply into one of
the multipin DC outputs on the back of the PS-5, then into the multipin Power Station input near the lower right corner of the
DDP-1. Do not plug the PS-5 into the AC wall socket until you have finished making all audio connections. Be sure to dis-
connect the stock AC power supply before you connect the PS-5 Power Station.
USB Programming Input
The DDP-1 is field-upgradeable, so you can update its firmware to add features and improve
operation. This input does not accept audio signals. To update the firmware, check the DDP-
1's screen during power-up to find out what firmware version you have, then check the Audio
Alchemy website to see if a new version is available. The website explains how to download
and install the new firmware. All you need is a computer and a USB cable with a USB-A plug
on one end and a USB-micro-B plug on the other. (This cable is commonly available; it's used
to charge Android phones and tablets as well as most Bluetooth speakers and headphones.)
