Transmitter AES3 Modes

The transmitter can be set up in three different con-

same manner as the transmitter for 4-channel opera-

Mixed Modes

TheselectedAES3modesonthetransmitterandre-

ceiver do not have to be identical. For example, analog

signals can be fed into the transmitter from a mixer or

wireless mic receivers, transmitted to the D4R receiver,

which can be conﬁgured for four digital outputs to feed

a digital recorder.

The sampling rate of the audio at the receiver digital

outputs will always be 48 kHz, regardless of the sam-

pling rate of the signal fed into the transmitter.

NOTE: Transmitter and receiver must be set for

the same number of audio channels.

Connector Pinouts

TA3M(3-pinmale)panelmountconnectorsareused

on the transmitter and receiver because they are

smallerthantheangemountedfemalejacks,andto

allow the use of right angle connectors such as the

RATPAC.ThesamepinnumberingasXLRjacksis

used for AES-EBU and analog audio devices.

Digital Signals – two audio channels per jack:

Pin 1: Shield (ground)

Pin 2: Signal

Pin3: Signal

Analog Signals – one audio channel per jack:

Pin 1: Shield (ground)

Pin 2: Audio (+)

Pin3: Audio(–)

When looking at the rear panel of the transmitter and

receiver,thepinsintheTA3Mjackarenumberedin

this pattern:

Polarityofpins2and3isnotimportantinthedigital

domain, but it is generally good practice to maintain

the pin to pin connections shown below when adapting

tostandardXLRconnectors.Adaptercableswiredthis

way can be used for both digital and analog signals.
