THE LEADER IN BASS AMPLIFICATION. World Tour 1205 Bass Guitar Amplifier Operation Manual Never Compromise™ ©09-20-2005 by U.S. Music Corp.
Bass Guitar Amplifier WT1205 OPERATION MANUAL Publishing Date 09-20-2005 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 World Tour products group is the result of our quest for ultimate bass tone and maximum reliability. Your new World Tour Amplifier was designed, engineered and manufactured equivalent to aircraft vibration standards and housed in a one-piece aluminum case with steel top to ensure maximum reliability. The modular design allows quick repair in the field should such a need arise.
FRONT PANEL FEATURES Input Jacks – 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. Both inputs are buffered and will handle standard passive, high level active, and piezo input signals. Both jacks can be used simultaneously with a single stereo instrument, or to connect two separate instruments.
Compressor Active Indicators – Light to indicate that the signal has crossed the threshold of the compression circuit and that compression is taking place. Enhance Controls – Called the “Magic Knob” by some, this complex control simultaneously boosts the very low bass, upper middle, and high frequencies while putting a dip in the lower middle frequencies. It is flat when set to its minimum level (fully counterclockwise).
We recommend you engage these switches at low volumes so that your sound remains consistent at any volume. At higher volume levels they aren’t needed but you may want to use them as a matter of taste. Because we strongly support Freedom of Choice, we’ve incorporated these two switches into our design. (You’re welcome.) Indicator lights to the outsides of the switches let you know when the boost circuits are engaged. AUX In – Blends the amount of Aux Input with the main inputs. D.I.
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 switch light can be on even if the fuse is blown. The light in the switch may flicker depending on local voltage conditions. This is normal and nothing to be concerned about. DC Power On Indicator – Lights to indicate that there is power throughout the entire 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 – 10 Amps, 5 x 20 mm GMC/T/slow blow Europe @ 240 Volts/50 Hz - 5 Amps, 5 x 20 mm GMC/T/slow blow Japan @ 100 Volts/60 Hz - 12 Amps, 5 x 20 mm GMC/T/slow blow IMPORTANT NOTE: Always use slow blow or time delay type fuses. Do not use fast blow fuses.
Footswitch Jack – Connect the Footswitch here. When connected, the footswitch overrides the corresponding front panel controls. Tuner Out Jack – This standard ¼ inch jack is designed to provide a pregain signal for connection to a tuner. It can also be used to provide pre-tone signal to other devices such as a direct box or console. The signal is hot enough to provide adequate signal to virtually every tuner on the market. Stereo Aux.
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. The cooling system also features a high temperature thermal safety system, which will activate a standby switch if the operating temperature goes above 190 degrees F. This circuit will automatically shut down the output of the system in the event of overheating.
Dual (Stereo) Channel Operation – Engage this switch when using stereo instruments. Engaging this switch will bypass the Channel Switching. Turbo Boost – Also known as the Solo Button, this engages a +6dB boost to put you on top of the mix. Use this for solos and such. This control is global, meaning that it affects both channels simultaneously. Enhance Bypass – Disengages the Enhance circuits, allowing you to instantly change tone.
Speaker Connections – If you are using the amplifiers separately, connect a speaker to each amp. DO NOT use the Bridge Mono speaker connection and make sure the Bridge Mono switch on the front panel is disengaged. If desired, you may use a single amplifier to run a single speaker. If you are using Bridge Mono, DO NOT use the individual amplifier outputs and make sure the Bridge Mono switch on the front panel is engaged. You can tell you are in Bridge Mono mode because the indicator light will be lit.
Once you’ve ensured correct voltage and speaker connection, 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 controls to the minimum position. Set the Input Gain controls to the minimum (fully counter-clockwise). Set the Compressor to the OFF position (fully counterclockwise). Make sure the Dynamic Boost switches are OFF. This will set your amplifier up flat and with the Compressors disengaged.
Setting the Compressor – If you want to use compression, engage it now by turning up the Compressor Threshold control. 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.) If you only want to compress your loudest notes, set this control to occasionally blink when you really dig in.
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 Clip light will engage. This is a Very Bad Thing and needs to be corrected immediately. If EQ clipping occurs, you can either decrease the boost or decrease the Input Gain.
We suggest you do some experimenting with the Midrange controls to better understand how they can affect your tone. While playing, boost and cut the Low Midrange so you can hear how it affects your tone. Remember to play in all ranges, not just on the first few frets. Once you have an idea of the tonal possibilities, return this control to FLAT and repeat the procedure with the High Midrange control. For Channel Two, turn the Frequency control fully counter-clockwise. Boost the Level control.
A FEW TECHNICAL THINGS TO REMEMBER Clipping = Bad – Keep an eye on the EQ Clip light. If it blinks, either reduce Input Gain or cut back on one or more EQ ranges. As we said earlier, Clipping in the preamp section is a Very Bad Thing and is to be avoided at all times. If you find yourself running out of amplifier headroom, cut a little in the lower frequencies, which require the most power from your amp. You’ll know this is happening if you see the Limit light flashing.
YOU’RE DONE. GO PLAY. There you have it: a quick and easy process to help you get the perfect tone from your Eden amplifier. As previously mentioned, it make take a few extra minutes the first few times you go through this, especially if you take the time to experiment with all the knobs and switches, which we highly recommend. We are confident that the time you spend getting to know your new friend is an important investment, one that will pay off immeasurably in Great Bass Tone.
Using the WT1205 Without Speakers -This amplifier is designed to be used safely with headphones only, without the loud speaker plugged in. No harm will result from using the amplifier in this fashion. This allows the use of the unit for practice with headphones and as a preamplifier with other amplifiers. Like we said earlier, neighbors and room mates really love this, which qualifies it as another Really Neat Thing. MAINTENANCE Your Eden amplifier has been designed to require minimal routine maintenance.
