Unpacking: Check that this package contains:
One 5.8 GHz Digital Audio transmitter - Model 1550, two 5.8 GHz Digital Audio
amplifiers - Model 1550, one small and two large AC adapters (wallwarts), four
short speaker cables, one RCA audio cable.

Step 1
Connecting the transmitter
The transmitter connects either to a standard line-out audio interface via the
supplied RCA cable or to an amplified speaker output via the supplied short
speaker cables.
If the transmitter is connected via speaker cables, observe the polarity of the
cable connection to ensure that the transmitter will be fed with a correct
polarity signal. If one of the cables is switched (reversed), one speaker will
receive an opposite polarity signal which will degrade sound performance.
The transmitter can also be connected to other audio outputs by using an
appropriate adapter.
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.
ATTENTION!
Do not use both the speaker cables and RCA cable. Do not connect
speakers to the transmitter. Do not connect the large AC adapter to
the transmitter.

Step 2
Connecting the amplifiers
Connect the DC power input of the amplifier with the supplied large 24 V AC
adapter (wallwart). ATTENTION: Connect the amplifier to the AC adapter
BEFORE connecting the AC adapter to the power outlet to avoid sparks due to
rush-in current.
Each amplifier connects to regular passive loudspeakers via the supplied speaker
cable. Observe the correct polarity when connecting the speakers.
Connect the left speaker to the amplifier marked “LEFT”. Connect the right
speaker to the amplifier marked “RIGHT”.
ATTENTION!
Never short circuit any amplifier audio output since this may
damage the amplifier. A clicking noise may be generated during
amplifier power up. Therefore, it is recommended to connect power
to the amplifier prior to connecting the speakers.

Step 3
Placing the transmitter and amplifiers
For best reception, we recommend that each amplifier be placed within the line
of sight from the transmitter. If possible, each amplifier should be placed right
side up with its front toward the transmitter.
The transmitter should be placed at an elevation such that there are no
obstacles between the transmitter and amplifiers (line of sight) in an area where
there will be the least amount of traffic. We suggest that you place the
transmitter on top of your audio source. Example 1 below shows the optimum
placement of the transmitter and an amplifier. If no line of sight is possible, place
the transmitter and amplifiers such that there is the minimum possible number of
walls and obstacles between the transmitter and each amplifier.
The amplifiers can also be placed as shown in example 2. In this case, no lineof-sight connection exists and the operating range is reduced.
You can mount the amplifiers vertically by using the 2 screw openings at the
bottom of each amplifier. If the amplifiers are mounted vertically, the operating
range is reduced compared to mounting the amplifiers right side up.
Each amplifier incorporates a directional antenna which prefers signals
transmitted toward the front of the amplifier. Therefore, the front of the amplifiers
should always be facing toward the direction of the strongest transmitter signal.
By properly orienting each amplifier, interference from other signal sources can
be minimized.
We suggest that you experiment with placement in order to find the best location
for the transmitter and amplifiers.
Note: This product will not work properly from within an enclosed metal cabinet.

Step 4
Operating the transmitter
After powering up the transmitter, the transmit light will go on for approximately
five seconds while the transmitter initializes.
After initialization, the transmit light will go out.
Initially, set the transmitter volume control to a middle setting.
Once audio is detected at the audio input, the transmit light will go on and the
transmitter will transmit the audio signal.
When audio is no longer detected, the transmitter will go into standby mode
after approximately one minute. The transmit light will go out. During standby
mode, no signal is transmitted.

Step 5
Operating the amplifiers
As soon as a valid transmitter signal is received by the amplifiers, the amplifiers
will output the amplified audio signal to the speaker outputs. The amplfier marked
“LEFT” will output the left audio channel and the amplifier marked “RIGHT” will
output the right channel. You can change the audio level by adjusting each
amplifier volume control.
In order to achieve maximum transmission quality, the transmitter volume control
should be set to match the audio level of your audio source as follows:
1) Set the amplifier volume control to a low level to prevent clipping inside the
amplifiers.
2) Set your audio source to output the maximum audio level that you will
encounter during normal operation such that both the left and right channel are
balanced.
3) Turn the transmitter level control knob to the position that yields maximum
audio loudness to the speakers without any clipping (distortion). If the
transmitter level is set too low, the dynamics of the transmission are not fully
used. If the level is set too high, audio clipping (distortion) will occur inside
the transmitter.
4) Turn each amplifier volume control to a setting that yields the desired volume
from the speakers such that the volume at both speakers is balanced.
If no audio signal is received for more than 2 minutes, the amplifiers will go into
standby mode (power-down mode).
