Getting Started
We realize that you can’t wait to hook up your
CR8S-XBT subwoofer and try it out. Nevertheless,
please take the time to read this page NOW, and
the rest can wait until you’re good and ready.
1. Turn the input level and sub output level controls on
the back of the cabinet down (fully counterclockwise)
before turning on the subwoofer for the first time.
2. Set the power switch on the back panel off. This will
prevent you from accidentally connecting a hot signal
source to the subwoofer and getting a rude surprise.
3. Connect the supplied AC power cord to the IEC socket
on the back of the subwoofer. Plug the other end into
an AC outlet properly configured with the voltage
corresponding to the markings next to the IEC socket.
4. Turn on the power switch on the rear panel
of the CR8S-XBT subwoofer.
5. Connect your device via Bluetooth

panel of the subwoofer (1/4" or RCA).
Connect the line-level signal from the output jacks
on the CR8S-XBT subwoofer to the studio monitors’
input jacks (1/4" or RCA).
6. Start your signal source (mp3 player, CD player, DAW,
8-track player, turntable, other), but leave the master
volume control down.
7. Turn on the power switch on the monitors.
Turn on the power switch on the CR8S-XBT.
8. Slowly turn up the input and sub output level controls on
the back of the subwoofer to center position (12 o’clock).

or other signal source to a comfortably loud listening level.

output levels and adjust the crossover to your desired
setting.

Additional Tidbits of Wisdom
• Never listen to loud music for prolonged periods.
Please see the Safety Instructions on page 2 for
information on hearing protection.
• When you shut down your equipment, turn off the
CR8S-XBT subwoofer first to prevent thumps and
other noises generated by any upstream equipment
from coming out the speaker. When powering up,
turn on the subwoofer last.
• Save the sales receipt and original packaging in case
you ever need warranty service. See page 16 for details.

An Extremely Important Note on CR8S-XBT Bass Response
and Your Control Room
The CR8S-XBT subwoofer achieve the best bass
response in a room that’s optimized for bass reproduction.
A lot of factors can conspire to thwart the extended
low frequency, including room shape, room volume
and acoustical treatment.
This is not a cop-out or an apology. It’s plain old
physics in action. Luckily we’ve armed you with some
compensating controls that you can use to optimize
the frequency response of the speakers in your particular
room. Consider the following:
When you put your CR8S-XBT in a corner or up against
walls, their bass characteristics change. The apparent
loudness of the low frequencies increases when
the subwoofers are placed close to a wall, and even
more so when they are placed in a corner.
