DSS Receiver Connection
The Out of the Box input configuration for a DSS receiver is set to use the optical digital audio output
of the DSS receiver as most DSS receivers have this type of TOS-Link jack. In the event your DSS
receiver features a digital audio coaxial jack, you may wish to use this connection instead of the optical
connection. Coaxial connections are better than optical connections, especially when basic optical
interconnects are all that are available.

TOS-Link Optical Interconnects & Audio Dropouts
The issue regarding TOS-Link optical interconnects stems from the manner in which they are manu-
factured. The most basic TOS-Link cables have the fiber optic line cut with a hot wire. Cutting the
fiber optic line in this manner forms a smooth reflective surface. It is this reflective surface which
causes digital data, in the form of light, to reflect off of the optical receiver, and in essence, back feed
into the TOS-Link interconnect. As such, the flow of light (the flow of digital data) is then interrupted.
This will cause audio dropouts during playback.
When selecting a TOS-Link interconnect, ADA strongly suggests using the very best cable available.
Typically, these cables offer some type of frosted tip which greatly reduces the reflective interference.
The very best TOS-Link interconnects provide convex tips which eliminate reflective interference.
If your DSS receiver features a digital coaxial audio output and you wish to use this type of intercon-
nect, follow the instructions as outlined on the next page.
