Carvin TR1801 User Manual

SPEAKER CABLES

Our standard cable for speaker hookups is the PH50. This cable features 1/4”
plugs and 16 gauge copper wire. The PH50 is adequate for lengths up to 50’ under
normal use. You can DAISY-CHAIN up to one additional speaker per cable by using
the unused 1/4” OUTPUT” jack (right side) on your speaker jack plate. Be sure to
note the total impedance to the amp so it is not lower than it’s recommended
impedance. See

Typical Loudspeaker Impedance Configurations.

Our professional SPK25, SPK50 & SPK100 cables feature Speakon™ lock-on
connectors with heavy 4 conductor 12 gauge copper wire. These cables are to be
connected in the same way as the PH50 with compatible amps.

PRECAUTIONS

1) DO NOT EXCEED THE POWER RATING marked on the rear connect plate.
Excessive power will destroy drivers. 2) DISTORTION from power amps will destroy
drivers much faster than clean power. 3) WATER, MOISTURE, and DUST are
harmful to drivers causing failure which is not covered under warranty.

TR1801

Congratulations on your selection of the 1801

sub woofer.

The 1801’s deep bass
qualities are excellent while its power handling capacities are one of the best in the
industry. The 18” cast frame, massive voice coil and magnet assemblies offer the
reliability needed even in the most demanding club or stadium Tri-amped situation.
Hookups are easy with either 1/4” jacks or professional Speakon™ connectors.

RECEIVING INSPECTION

INSPECT YOUR SPEAKER FOR ANY DAMAGE which may have occurred during

shipping. If any damage is found, please notify the shipping company & CARVIN.

SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship
your unit, always use the original carton and packing material. This will provide the best
possible protection during shipment. CARVIN and the shipping company are not liable
for any damage caused by improper packing.

SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.

SHIPMENT SHORTAGE. If you find items missing, they may have been shipped
separately. Please allow several days for the rest of your order to arrive before inquiring.

RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this
manual for your records. Keep your portion of the card and return the portion with your
name and comments to us.

SUGGESTIONS FOR OPTIMAL PERFORMANCE

Raise the enclosure to the ear level of your audience for greater coverage. To help
control feedback, use a graphic equalizer. Keep the speakers in front of the
microphone. Never direct the microphone towards the speaker. For greater
coverage, add a second speaker system 20° to 30° off axis.
