The A-16T Rear Panel
On the rear of the A-16T Transmitter you will find the power connector, the sixteen
audio inputs, and the sixteen Thru jacks.
Signal routing into and out of the A-16T Transmitter has been designed to be extremely
flexible, allowing the A-16T to integrate into virtually any audio environment.
Power Connector
Your A-16T Transmitter comes with a switching-type power supply. This type of power
supply can be used with a wide range of AC wall current outputs, meaning that you
do not need to replace the power supply if the unit will be used in different countries
throughout the world where current voltages are different. (You may, however, need
plug adapters to allow the power supply to be connected to wall outlets internationally
since many countries use different physical plug layouts for their power systems.)
Channel Input Jacks
The rear panel of the A-16T Transmitter contains sixteen Input jacks (labelled In).
These jacks can accept balanced or unbalanced signals on 1⁄4-inch plugs.
Balanced signals (sometimes referred to as TRS, for Tip, Ring, and Sleeve) are found
on many professional audio devices. The 1⁄4-inch connector used for balanced audio
wiring has three conductors: the tip, the ring, and the sleeve. It is the same connector
found on most stereo headphones, for example. The balanced wiring system is ideal for
keeping noise out of the audio signal from sources such as radio interference (some-
times called “RF”).
Unbalanced audio signals are found on many keyboards, effects processors, etc. Only
two connectors are used, the tip and the sleeve. A standard musical instrument or guitar
cord uses this configuration, for example.
Channel Thru Jacks
The Thru jacks on the A-16T provide the user with an exact copy of the signal plugged
into the In jack just below it. This can be used as a way to insert the A-16T Transmitter
into a signal chain without giving up audio patching flexibility.
The Thru jacks have other uses as well. While a direct output from a mixing board is
the most straightforward way to connect audio from your mixer to the A-16T, some
