Eden Electronics Operation Manual World Tour Series Preamplifier The Navigator WP-100 Bass Preamplifier Professional Bass Guitar Preamplifier for live performance and direct Studio Recording interface applications.
WP-100 Operations Manual Forward Congratulations, on the purchase of your new Bass Guitar Preamplifier. This unit is all carefully hand built by Eden Electronics and is of the finest Professional Bass Preamplifiers available today. The WP-100 offers a unique combination of Vacuum Tube and FET electronics. The WP-100 offers a warm but well controlled studio quality sound. A variety of features assure that there are endless possibilities for patching in and out of the three effects loops, the three D.I.
DESCRIPTION OF THE FRONT PANEL CONTROLS Input Jack The input is routed directly to the Vacuum Tube (7025) and will operate properly with any input signal level up to a maximum (+21 dBm) input level from the Bass Guitar. This eliminates the need for a separate input pad. Gain Control The Gain control is used to set the relative gain level requirements and to adjust the signal input level to match your Bass Guitar's output level to the Preamp.
Enhance Bypass This switch allows the Enhance control to be turned on and off by panel or foot switch. It's a great feature for doing a quick tone change while playing. As with the other controls the panel switch overrides or takes control from the foot switch. The red LED will be on when the switch is depressed. The Bypass is engaged when the red LED is on. Set Signal Level / Head room indicator This is the LED located between the Gain and Enhance Controls.
Studio Quality Compressor The Navigator's internal studio quality compressor uses a dBx style, state of the art compressor chip with a fully adjustable Ratio and Threshold. The recommended starting point for control settings is around 1:00 for the Threshold control and around 11:00 for the ratio control. A good general setting for the overall compressor operation is to match the Compressor operating LED (located between the Ratio and Threshold controls) to go on at the same time as the level set indicator.
Treble Control The Treble control is also a shelving type filter and boosts or cuts the Treble by +/- 15 dB. Flat position is at 12:00 o'clock. Semi-Parametric Tone Controls (Quasi-Parametric) Quasi-Parametric controls are similar to fully parametric controls with the exception that they do not have an adjustable bandwidth control. That adjustment is fixed by design. All the filters are adjustable by +/- 15 dB. All these controls are flat at the 12:00 position.
Side Chain Effects loop Level Control The side chain loop is configured to operate in parallel with the tone controls. This allows a special effect or signal to be added across or blended with the internal tone controls. The return level control allows the Artist to blend the exact amount of effect desired. Stereo Auxiliary Input Level Control This is a full stereo input at line level and allows the Artist to mix sends from monitors CD players, ADATs, or recording consoles into the bass system.
Master Level Control This is the final output level control. It controls both the Main outputs, and the left and right D.I. outputs. For normal use the Master should run from around the 9:00 position to about the 12:00 position on the control. It is possible to put enough extra gain on the output section to induce some clipping in the final part of signal chain if you crank up both the input and output to near maximum with a very loud Bass.
Mains On / Off This is the master power switch. It is always advisable to turn the Master Level Control down during turn on and turn off. Automatic Master Muting Systems On your Navigator the Main D.I.s left and right, and the Left Right 1/4" outputs are muted. The Instrument D.I. is also muted. Front Panel Lights These are powered by the D.C. supply.
Fuse holder AC Inlet This is a standard IEC connector interface. The Fuse should be replace only with the same size and type. The correct fuse is 1 amp for the USA @ 120V. Contact you local distributor for all Foreign voltage applications. The Navigator is set up to work with most International Voltages. Some require a minor jumper change inside the unit. Refer any work of this type to a qualified service technician. DO NOT ATTEMPT TO CHANGE INTERNAL AC CONNECTIONS OR REPAIR THIS UNIT YOURSELF.
Tuner Output Send The tune output send is direct from the Vacuum tube and is not muted during any of the automatic or manual muting modes. It allows for a tuner to be plugged in at all times. This output is at the same relative level as the output of the instrument times 1 or unity Gain. Foot Switch port (DIN) The optional foot switch is connected via this port with a standard 5 wire MIDI cable. One is provided with the foot switch.
Normal set for the USA 120V 60Hz : White (Neutral )to P9, Black to (AC Hot ) P11. Japan 100V 60Hz: White to P10 (20V) Black(AC hot ) to P11. Western Europe most EC counties and Italy 240/230V 50Hz: White (Neutral) to P9 0V Black (AC Hot)to P12. Switzerland 220V 50Hz: White (Neutral) to P10 Black (AC hot) to P12. For your protection always use a correctly grounded AC receptacle only. Do not disconnect your ground plug. This is your safety ground.
