THE LEADER IN BASS AMPLIFICATION. World Tour Bass Guitar Pre-amplifier Covering Model WP100 Navigator Never Compromise™ ©02-01-2006 by U.S. Music Corp.
Bass Guitar Pre-amplifier WP100 Navigator OPERATION MANUAL Publishing Date 02-01-2006 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.
Please read this manual in its entirety before operating your new amplifier. Failure to do so could result in misuse or damage. We’ve taken the time to write it, which was a lot longer than the time it will take for you to read it. Help us help you by taking a few moments to learn how to properly use your new amp. You’ll be glad you did! CAUTION! Your ears are your most important piece of equipment. Unfortunately, they cannot be replaced as easily as your other gear.
FRONT PANEL FEATURES Input Jack – Designed to accept a standard 1/4-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. Mute switch – Mutes all the outputs except the Tuner Out, allowing for silent tuning. Lead singers and guitarists love this feature! The indicator to the left of the switch lights up when Mute is ON.
Enhance Bypass Switch – disengages the Enhance control for a quick change in tone. The indicator to the left of this control will be lit when the Enhance circuit is bypassed. This switch is duplicated on the footswitch. Turbo Boost Switch – Engages the +6dB Turbo Boost for instant volume change. The indicator to the right of this switch will be lit when the boost is activated. This switch is duplicated on the footswitch.
Mode Selector Switch – Your Navigator can be operated in Stereo or Biamp mode. This switch allows you to choose which mode is used. Limit Switch – This switch enables the internal stereo Output Limiters to be engaged with the final Main Outputs. The Limiters are calibrated to two standard Power Amplifier input voltage requirements: high voltage standard (such as a Crown amplifier) @ 2.8VRMS and low voltage standard @ 1.4VRMS.
IMPORTANT NOTE: DO NOT use this jack for a Mono Signal Send! It may be possible to damage the mono headphones inserted into this jack, as well as your Navigator. USE ONLY STEREO HEADPHONES! Don’t say you weren’t warned, because you were! 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. The light in the switch may flicker depending on local voltage conditions.
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. All models come with a holder marked (FUSE) or (115/230) and are factory configured for 100/120/ 230/240 only and must be adapted by a service tech for any voltage change. Fuse Requirements: USA @ 120 Volts /60 HZ – 1 Amp, 5 x 20 mm GMC/T/slow blow Europe @ 240 Volts/50 Hz – 0.
Main D.I. Outputs – These fully balanced stereo XLR outputs provide +16dBm maximum. They can be used to send a stereo signal to a mixing board or recording console, or to connect to a power amplifier. Please note, however, that the signal from these outputs is not as hot as that from the Main Outputs. Recording Out (D.I.) – This fully balanced XLR output allows you to send a signal to a recording or sound reinforcement mixing console. We use Pin 2 hot configuration.
Stereo Post-EQ Effects Send/Return – These standard 1/4-inch jacks allow you to send and receive your signal to and from external devices. This effects loop is positioned post (behind) the tone section. This loop is at line level; do not use instrument level effects in this loop as they tend to be overloaded by the higher signal level which can cause distortion. To use with mono effects, return the signal to the Left return.
INITIAL SET UP Before turning your Navigator ON, you must first determine which mode of operation you wish to use. It is critical to the safety of your unit that you make all connections correctly, and that you set the switches to the proper position. Failure to do so may result in damage to your preamplifier, amplifier &/or speakers! Connect the appropriate cables to the various outputs on the back panel. Check to make sure the front-panel switches are set for your desired mode of operation.
Once you’ve established that your unit is set to the correct voltage, set the Master Volume control to minimum (fully counter-clockwise). Set the tone controls to the center position (12:00 or 0). Turn the Enhance control to the minimum position. Set the Input Gain control to the minimum (fully counter-clockwise). Set the Compressor to the OFF position (push the switch IN). This will set your Navigator up flat and with the Compressor disengaged.
The ratio is variable from very soft compression (fully counter-clockwise) to hard limiting (fully clockwise). The Compressor light will 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.
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 our power amplifiers 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.
