World Tour Bass Guitar Amplifier Covering Model WT550 THE LEADER IN BASS AMPLIFICATION. ©08-10-2005 by U.S. Music Corp.
Bass Guitar Amplifier WT550 OPERATION MANUAL Publishing Date 08-10-2005 FORWARD Congratulations on the purchase of your new Eden World Tour Integrated Amplifier System. All of us at Eden are totally committed to providing you with the very best bass guitar systems in their class.
The Eden line of World Tour amplifiers is the result of our research and development in combining high performance and compact size. Just as a skilled craftsman needs good quality tools that won't let him down on the job, so does a good musician. We hope you enjoy the tool we’ve created for you. Have fun; play low! Please read this manual in its entirety before operating your new amplifier. Failure to do so could result in misuse or damage.
FRONT PANEL FEATURES Input Jack – Designed to accept a standard ¼ inch mono phone plug. For best results use a high quality shielded cable to connect your instrument to the amplifier. The input is buffered and will handle standard passive, high level active, and piezo input signals. Gain Control – Regulates the first gain stage of the preamplifier and controls the amount of signal available to the system. Input Pad – Pull the Gain control out to engage a –12dB pad on the input stage.
Semi-Parametric Controls There are three sets of semi-parametric controls. Each set has a Frequency control (top knob) and a Level control (bottom knob). The Level controls provide 15 dB of cut or boost. The control is FLAT in the 12:00 position. From left to right, the Frequency controls have the following ranges: 30-300Hz 200Hz-2KHz 1.2-12KHz Treble – This traditional shelving tone control provides 15 dB of boost or cut at approx. 11KHz. The control is flat in the 12:00 position.
Combination Power Cord Jack and Fuse Holder – The removable power cord is attached here. To access the fuse holder, pull the holder out of the top of the power receptacle. Your unit was shipped with a spare fuse inserted in the fuse carrier. USE ONLY THE SAME SIZE AND TYPE FOR REPLACMENT. Using a fuse with a different rating than specified is a VERY BAD THING and can cause damage to your amplifier.
Recording Out (D.I.) – This fully balanced XLR output allows you to send a pre- or post-EQ signal to a recording or sound reinforcement mixing console. We use Pin 2 hot configuration. Adjusting the Master Volume control will not affect this send. This output is designed to use with phantom powered systems. However, it never hurts to turn off the phantom power at the board, if possible. D.I. Level – Controls the level being sent from the XLR balanced output jack.
The cooling system also features a high temperature thermal safety system, which will activate an AGC (Automatic Gain Control) circuit if the operating temperature goes above 200 degrees F. This circuit will automatically turn down the output of the system in the event of overheating. It will automatically reset itself to full power as soon as the unit cools down to a safe operating temperature. NOTE: the D.I. will continue to operate normally even when the amplifier is in thermal safety mode.
INITIAL SET UP As bassists, each of us has in our head a concept of our perfect sound. Eden amplifiers are designed to help you easily achieve the sound you hear inside you. However, it’s a multi-step process as explained below. In order to ensure the ultimate in tone, it’s important to follow the procedure outlined below. Don’t skip steps; don’t jump around. Yes, this may take a minute or two, but the work is well worth it.
If you have disengaged the Compressor as we suggested, the Set Level light will barely blink on your loudest notes when you reach clipping in the Input stage. We recommend you decrease gain one or two clicks to ensure there is no clipping in the system. By the way, this is David’s favorite way to set level, even if you intend to use compression. Once you have properly set your Input Gain, turn the Master Volume up to a comfortable listening level and proceed with the rest of the setup process.
Slowly bring the Enhance control up while playing. If you turn it up close to 12:00 on the dial and still don’t have your sound, stop there. Return the Enhance to OFF or leave it at no more than 12:00 and work with the EQ section. Using the EQ Controls – Before you begin to twiddle knobs, let’s talk about a few things. Excessive boosting of one or more EQ frequencies may cause an overload in the EQ section. If this happens, the EQ Clip light will engage.
Now, cut the Level control to approximately 3:00 and do the same thing. Repeat this process with the two remaining control sets. By the way, this process is a lot easier if you have a friend do the knob twiddling while you play. Here are a couple of tips to help you dial in your desired tone: For a great fretless tone, dial in a little extra at approximately 550Hz. For extra grind for Rock and other aggressive music, add a little at 1-1.2KHz or 2-2.
Frequency enhancement results from cabinet placement and room acoustics. A cabinet placed on the floor will have the lower frequencies boosted by about 3 db. Placement against a wall adds another 3 db. A corner adds 3 db more. Consequently you may find a surprising boominess to your sound. Certain qualities in the room itself can also enhance the lower frequencies, further contributing to this problem. Frequently this effect is more noticeable in the audience than it is on stage.
We have designed our amplifiers to operate safely at 2 Ohms only because everyone else is doing it and some users expect it. However, we much prefer operating at 8 or 4 Ohms because of the markedly improved quality of tone and dynamic response. But if you really want to, you can operate your WT550 at 2 Ohms without worry.
Dust Removal – You should periodically inspect the ventilation openings on the top and sides of the unit to ensure that they have not become blocked by accumulated dust. Vacuum the openings to remove any dust buildup. Dust bunnies are definitely not cool. The Magic Smoke – Few people realize just how much magic goes into creating Great Bass Tone. It isn’t something you normally need worry about. Just have fun and leave all that to us.
Service – In the event of amplifier malfunction, or questions about your unit’s operating features that aren’t answered in this manual or on our website, you should contact your Dealer. Once you and your dealer have determined it’s definitely a malfunction (and not an operator error) you must call our Customer Service Department and obtain a Return Merchandise Authorization (RMA).
