Step 1
Connecting the transmitter
The transmitter has two stereo audio inputs, one zone-A and one zone-B input.
4 audio channels can be transmitted simultaneously. Both zone-A and zone-B audio
inputs can connect either to an unbalanced line-level audio output or a balanced
amplified speaker output. For best audio quality, we recommend using the
unbalanced line-level audio input.
The transmitter can transmit to Model 400 wireless audio receivers and Model 480
wireless amplifiers. Each audio channel is encoded with a channel ID and can be
selected by each wireless receiver.
Regardless of whether any specific audio channel is transmitted to a wireless
receiver or wireless amplifier, both the transmitter line-level and amplified speaker
audio inputs can be used to feed audio into the transmitter.
Connect the transmitter to an unbalanced audio input by using the supplied phone-
RCA audio cable. Connect the phone jack with the line level input of the transmitter
and the RCA jack with the RCA output of your audio source.
Alternatively, connect the transmitter to an amplified speaker output by using the
supplied speaker cables. Be sure to observe the correct polarity of the speaker
cable.
Note:
If one of the speaker cables is switched (reversed), one speaker will receive
an opposite polarity signal which will degrade sound performance.
It is possible to connect zone-A audio inputs to line-level audio outputs and zone-B
audio inputs to amplified speaker outputs and vice versa. However, only the
unbalanced line level input or speaker inputs of each zone can be used, i.e. you
cannot mix audio inputs within a zone.
Connect the supplied small AC adapter’s barrel-shaped plug into the DC 9V jack,
and then plug the transformer into a standard AC outlet. We recommend the use of
a surge protector to protect the transmitter from power surges.
Unpacking:
Check that this package contains:
One 5.8 GHz Digital Audio transmitter - Model 400, one 9 V AC adapter (wallwart),
four short speaker cables, two RCA audio cables.
ATTENTION!
Do not connect both the line level audio input and amplified speaker
audio input of the same zone. This may damage your audio source.
