Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Transmitter: The system comes
with a Radio Frequency omnidirectional transmitter/charger that connects to an
audio source via analog stereo preamp connection. It transmits a 900 MHz signal
up to 250 feet to the wireless speakers, using one of three
selectable transmission channels. A channel select switch on the transmitter allows the use of other
900MHz equipment in the same area as the speakers are being used to avoid
Speakers: The self-powered, 7.5
watt speakers are a Two-way acoustic suspension design. Each speaker features a
2" dome tweeter and 5" cone woofer with a 20 to 20kHz frequency response.
The speakers have a left/mono/right switch on the back so you can use the
speakers as a stereo pair in one room or as separate mono speakers in different
rooms. Each speaker is powered by either the supplied AC power adapters or by 8
"C"-cell batteries (not included). Four phillips-head screws will need to
removed to access battery compartment on back of each speaker.
Note: If you are using
rechargeable batteries, the batteries will charge when the speakers are
powered with the AC power adapters. The AC adapters will charge rechargeable
NiMH or NiCd batteries (not included).
Audio Signal Indicator Light: There is an audio signal
indicator light on front of the transmitter that lights Blue to inform you that
the transmitter is receiving an audio signal from your source component.
Integrated Power/Tuning Volume Control:
Each speaker has an integrated Power/Tuning/Volume knob on the front below its
grill. Push the rotary knob in to turn the power for the speakers "On" and to
start tuning the speakers. The "standby/charging indicators" on the front of the
speakers will illuminate red while the speakers are automatically tuning to the
transmitter. The "tuned" indicators on front of each speaker will illuminate
blue indicating that the speaker are tuned to the transmitter. Now you can use
the integrated knob to adjust the volume of the speakers up and down by rotating
Note: Once the speakers have tuned to
the transmitter and the blue "Tuned" indicators are on, the red
"standby/charging" indicators will turn off.
Auto Tune: The speaker will automatically
retune if it loses the signal from the transmitter. However, you can also push
the integrated control to retune the speakers at any time. While the speaker is
tuning, the blue "tuned" indicator will turn off and the red "standby/charging"
indicator light will turn on.
Phase-Locked Loop: Phase-Locked Loop technology guarantees
crystal clear audio from the speaker by locking onto the transmitter's signal
for more precise, accurate tuning.
Turn Off: Push and hold the integrated
control in for about 1.5 seconds to turn the speakers off. Confirm that the
speakers are off by verifying that the red and blue light are off.
Built-In Carry Handle: Each speaker's built-in carry handle
lets you move the speakers easily from room to room.
Transmitter: The 900Mz transmitter uses an attached 6' male
mini-jack cable and comes supplied with a mini to stereo RCA adapter and a 3/4"
headphone adapter. The unit also features a DC input for use with the supplied
