Connections and
Installation
The Ayre QA-9 is easy to connect and use. The
following guidelines will ensure that the installation
goes smoothly.
Analog Inputs
The Ayre QA-9 offers balanced inputs. Balanced
connections are made via three-pin XLR connectors.
High quality singled-ended-to-balanced adapters
are included for single-ended analog sources.
USB Output
Connection via the USB
output simplifies operation, as
many of the converter settings
can be adjusted with your
computer’s software.
The USB output uses the squarish “B” type
connector designed for computer peripheral devices.
The rectangular “A” type connector at the other end
of the cable is designed to plug directly into the
computer itself.
The USB 2.0 standard specifies a maximum cable
length of 16 feet (5 meters); It is not recommended
to use extenders or hubs with the QA-9.
