EDEN THE LEADER IN BASS AMPLIFICATION. DC210XLT Metro Combo Bass Guitar Amplifier Operation Manual Never Compromise™ ©03-15-2006 by U.S. Music Corp.
Combo Bass Guitar Amplifier DC210XLT Metro OPERATION MANUAL Publishing Date 03-15-2006 FOREWORD Congratulations on the purchase of your new Eden DC210XLT Metro Combo 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 Channel 1: 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. Gain Control – Regulates the first gain stage of the preamplifier and controls the amount of signal available to the system. Input Pad – Depressing this switch engages a –10dB pad.
1. To choose between instruments. Plug an instrument into each of the channels and use the switch to select the proper channel of operation. This is a great feature for those who double. 2. To use a single instrument with both channels. Plug your instrument into the Input Jack for Channel 2 (Master Channel) and use the Channel Selector Switch to instantly switch between two different tone settings. This is a great way to have instant access to a second tone/volume setting, e.g., for solos or slapping.
Compressor Defeat Switch – To defeat the Auto-Compression circuit, depress this switch. Compressor Indicator Light – Indicates compression is taking place. Tone Control Section Here’s where things are a bit different than Channel 1. This channel uses our original 5-way semi-parametric EQ. These controls offer more tone shaping options. The spacing allows the controls to interact smoothly and musically.
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. This is normal and nothing to be concerned about. NOTE: The Mains Switch will illuminate even if the fuse is blown. However, the DC Indicators will not illuminate if the fuse is blown.
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.
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 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.
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.
Setting Your Level – Remember, begin with the Input Gain, Enhance, Compressor and Master Volume completely OFF – fully counter-clockwise. All EQ should be set flat, that is, at 12:00 – straight up. While playing your lowest note (or loudest), slowly turn the Input Gain up until the Set Level light begins to blink with regularity. If you can’t go past 8 or 9 o’clock, you may engage the Gain Switch to better match the gain of your instrument to the amplifier.
Enhance – Once you’ve set your gain, you can move on to setting your EQ, beginning with the Enhance control, or Magic Knob, as some call it. The Enhance circuitry adds very low bass, upper mids and highs while scooping out a bit of low middle. The more Enhance effect you dial in, the greater the boost (and cut). As with all of our EQ controls, a little goes a long way. 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.
Beginning with all controls FLAT, turn the first (left) frequency control fully counterclockwise. Turn the corresponding Level control to approximately 9:00. Now, while playing, rotate the frequency control to the right a little at a time. You should be able to easily hear the frequencies this first set of controls affects. Now, cut the Level control to approximately 3:00 and do the same thing. Repeat this process with the two remaining control sets.
As a result of this masking, you find that the EQ settings that were so perfect at home lack definition in a live setting. On the other hand, the stage settings that worked so well sound harsh and/or thin in the absence of other instruments. 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.
It will actually take about 24 to 50 hours of total playing time to fully break in your speaker system. If desired, you can plug a CD player into your amplifier and play a CD through your enclosure to accomplish this break-in. Connections With Additional Cabinets – It is important to keep two issues in mind when using your DC210XLT combo with other speaker cabinets: phase relationships and impedance.
If you are uncertain about your future needs, always go with the 8 Ohm speaker option so that you can add another speaker later if you need to. In general, adding more speakers will give you a greater volume increase than adding a few more watts. 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.
Cabinet Placement – The placement of your cabinet can also have an impact on the amount of bass it produces. Placing the unit on the floor increases the amount of Bass you get by an additional +3dB . With each additional wall surface placement you get another 3 dB increase. This is due to the reinforcement of bass frequencies by the adjacent surfaces. The absence of reinforcing surfaces is the reason why outside settings are so problematic for bass amplification.
Contact Point Cleaning – One of the weakest links in most bass amplification systems are the solderless connection points where instruments, speaker cabinets, effects, and other devices are connected to the amplifier. (The most vulnerable of these types of connection is the jack on your instrument). In addition to contamination from airborne pollutants, these points are frequently assaulted by connectors that have picked up debris from dirty stages, cases, etc.
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).
