Bass Guitar Amplifier WT800B OPERATION MANUAL Publishing Date 07-15-2005 FOREWORD 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.
CAUTION! Your ears are your most important piece of equipment. Unfortunately, they cannot be replaced as easily as your other gear. Please take the following warning seriously. This product, when used in combination with loudspeakers and/or additional amplification may be capable of producing sound levels that could cause permanent hearing loss. DO NOT operate at high volume levels or at a level that is uncomfortable.
FRONT PANEL FEATURES Input Jack – Designed to accept a standard _ 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. Set Level Indicator – This light helps the user set the appropriate amount of gain.
EQ Clip Light – indicates clipping in the EQ section. Clipping is a Very Bad Thing and should be avoided at all times. We’ll tell you how to avoid this later in the manual. Compressor Defeat Switch – To defeat the Auto-Compression circuit, depress this switch. Compressor Indicator Light – Indicates compression is taking place. Master Level Control – Adjusts overall system output and stage loudness. Bi-Amp Switch – Engages Bi-Amp Mode.
Output Limit Indicators – Light to indicate activity of the power amplifier limiting circuit, which protects the speaker system from severe distortion. These LEDs indicate that the amplifiers have reached their maximum output level. DC Indicator – When lit, shows that the low voltage power supplies are operating. Mains On/Off Switch – This switch turns the system power ON or OFF. The switch illuminates to indicate the presence of AC power present in the chassis. This switch is prior to the fuse.
Bridge Mono Output – This is a single NL-4 connector to be used ONLY in Bridge Mono operation. . The total speaker load impedance should not go below 4 ohms. 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.
D.I. Level – Controls the level being sent from the XLR balanced output jack. We suggest setting the control at approximately 12 o’clock initially. If the signal to the board is too hot, it’s better to engage the Input Pad on your channel of the board than to turn it down here, if at all possible. In general, it’s better (in terms of signal-to-noise ratio and dynamic presentation) to send as hot a signal as possible to the board.
Right/Low Amp Output – These consist of two _ inch jacks and an NL-4 connector (sometimes called a Speakon). The jacks are wired in parallel. The total speaker load impedance should not go below 2 ohms. On NL-4 connectors, we use +1, -1 connections. Cooling System – Your amplifier features a thermostatically controlled fan, which will switch on when the internal temperature reaches 130 degrees F. In low volume situations (into 8 Ohm loads) the fan may not come on at all.
Connections – All instrument-level input connections (everything but the speakers) should be made with high quality shielded cables. The use of speaker cables for input connections will result in excess noise. Speaker connections should be made with high quality 16 gauge or heavier unshielded speaker cables. We recommend 10 or 12 gauge cables. The use of shielded line or instrument cables for speaker connections can damage your amplifier. The speaker cable should be as short as possible.
Make sure the Bi-amp switch is OFF, or flush with the panel. Set the Balance control to the 12:00 position. Bi-Amp Operation: Connect the appropriate speakers to each individual amplifier Output. Engage the Bi-Amp Operation switch. When ON, the switch will stick out slightly from the face of the amplifier. Make sure the Bridge Mono switch is OFF, or flush with the panel. Use the Crossover control to determine which frequencies will go to the speakers.
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. Once they’ve done it a few times, most users can do it time and again in about a minute. IMPORTANT NOTE: Before you plug in your unit for the first time, please do the following things. First, turn the power switch to the OFF position.
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. Setting the Compressor - If you want to use compression, engage it now by turning the Compressor Defeat switch OFF. The compressor light will now blink when your gain goes above the compression threshold. This will generally show up more on the lower notes, or when you employ Slapping. (A properly compressed Slap sound is very cool, indeed.
If EQ clipping occurs, you can either decrease the boost or decrease the Input Gain. Remember, too, that our EQ controls are active, and are meant to turn both ways – not just UP! This means that you can enhance a certain frequency spectrum either by boosting that frequency or by cutting the adjacent frequencies. This latter method has the advantage of maximizing potential headroom. If possible, step well forward of your rig to get a better idea of how you will sound in the room.
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 2-2.2KHz – or both! Remember, though, that a little goes a long way. Don’t over boost. NOTE: Remember that the tone you get when playing alone may not cut through as well as you’d like when playing with others.
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 WT800B at 2 Ohms per channel without worry. In Bridge Mono Mode, the total impedance should never be less than 4 Ohms. This translates to a 2 Ohm load for each amplifier.
This contamination can result in poor contact as well as poor tone, and we all know that bad tone is a Very Bad Thing. These points should be cleaned regularly with a cotton swab soaked in denatured alcohol or a commercially available de-oxidant. Frequent cleaning of the plugs on your cords is also recommended. 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.
