1. Preamp Mode Switch
Depending on your preference, choose either solid-state or tube gain input for the preamp.
2. 0dB / Passive and -6dB / Active Input Jacks
We suggest the following: use the 0dB/Passive input for bass guitars with passive electronics, like single-coil and humbucking pickups; use the -6dB/Active input for active pickups (or extremely 'hot' pickups). However, you may prefer to run your active pickup bass guitar into the 0dB/Passive input for an intentional aggressive sound – you are in control.
User Tip: Don't use both inputs at the same time as they're not intended for connecting more than one instrument at a time.
3. Gain Control
The Gain control is a volume adjustment for the preamp, which is selectable - using either solid-state or tube circuitry. The tube circuitry features a single 12AX7A (dual-triode) preamp tube. The Gain control should normally be set around the middle, which should be the position for most basses. If your bass has an unusually low output, increase the Gain control to the desired level, conversely for higher output basses use a lower setting. Increasing the Gain control also affects the level of distortion when the Distortion feature is engaged.
4. Distortion Switch, Mix and Control
The Distortion feature controls the amount of tube distortion (saturation) in the signal. The tube distortion is powered by a 12AX7A, dual-triode preamp tube. Activate the circuit by depressing the Distortion mode switch or using an optional footswitch (AFS-2). The red LED, above the Distortion switch, will illuminate indicating Distortion mode is active. To achieve higher levels of overdrive, increase the Gain control at the preamp stage. If you want your distortion level to go beyond the usual threshold into modern lead-style distortion, increase the Distortion control fully clockwise. Naturally, there will be some extra noise coming out of the amplifier at this high setting. This is a normal compromise when achieving so much overdrive.
User Tip: Many unique sounds can be obtained by changing some controls in conjunction with the Distortion control. Some bassists prefer minimal distortion with a lot of Scoop, some may prefer massive overdrive (and lots of midrange growl) and others may go for that deep dry bass. These sounds can be achieved easily by adjusting the Scoop, the Distortion and the Distortion's Mix controls in conjunction with each other.
User Tip: The Distortion circuit can also be activated by an optional footswitch (AFS-2). A red LED, located directly above the Distortion switch, will illuminate. Some players find this useful as a boost for loud passages or soloing.
Note, when using the footswitch the front panel Distortion selection switch is deactivated.
The Distortion Mix control becomes active when the Distortion mode is activated. This control blends an underlying clean tone below the distorted tone. In the Dry counter-clockwise setting, clean signal is allowed to dominate the mix with no distortion. When rotated clockwise, into the Wet region, the distortion sound becomes more apparent. The Distortion overdrive will continue to increase until it is the dominant sound in the mix (fully Wet position). This helps you achieve a perfect Wet/Dry blend between a completely clean and completely saturated distortion tone. This is a handy feature that puts you in control of your distorted tone.
5. Compressor
To increase the consistency of your tone and further the performance of the power amplifier, we have provided an adjustable compressor. This compressor is fairly simple to use, with only a simple threshold control to make adjustments. The compression ratio is 2:1 and the attack/release-time is preset optimally.
Note: To use the Compressor, rotate the control clockwise until the desired threshold is reached. It will be apparent to you audibly as well as visually; a red LED (located to the right of the control) will illuminate as the compressor limits the signal. The LED will also indicate how much compression is being applied by its intensity and duration.
6. Tone Controls
Each tone control permits a wide range of adjustment. The five overlapping controls cover the entire audio spectrum. The Bass adjusts the level of the low frequency range, Low Mid the next range up, Hi Mid covers higher notes and middle harmonics and the Treble control regulates the upper harmonic range. Each tone control has a variable boost and/or cut of 15 db. The center position denotes a neutral or nominal setting. The Parametric Mid control is described in detail in section 7, below.
User Tip: It's a good idea, when starting out, to center all tone controls. While playing, adjust them until you achieve the desired sound. Remember, if the Parametric Mid control is set at 0, rotating the Frequency control will have no effect.
7. Parametric Mid Control
The Parametric Mid control enables adjustments to be centered on frequencies ranging from 150Hz - 15kHz .
User Tip: To use this control, set the position of the Parametric Mid level control to cut or boost. Rotate the Frequency control until the desired frequency range is found. Once the frequency range is chosen, adjust the Parametric Mid level until the desired cut or boost level is achieved.
User Tip: Try using the Parametric Mid in conjunction with the Scoop feature. When using the Parametric Mid, it's possible to enhance the Scoop's capabilities by letting the two tone-shaping controls work in tandem. If you like the added bottom of the Scoop but wish to soften the midrange at 1 kHz (but still maintain the higher frequencies); adjust the Parametric Mid Frequency control to 1.0 kHz and then use the Parametric Mid level control to cut as much as you need. The 400 Hz frequency has been conveniently marked on the Parametric Mid's Frequency control.
8. Scoop Control
The Scoop enhances the tone of the bass by shaping the mid frequencies around 400Hz . By shaping the bottom-end fundamentals and high frequency brilliance subtleties normally hidden are revealed. The Scoop shapes specific upper and lower frequencies while notching particular mid frequencies. It utilizes a variable tone curve that reacts differently depending on where it is set. The result is a greatly expanded tonal range and control. As shown on the front panel, the center frequency of the scoop is centered around 400Hz . If you desire more scoop, turn the parametric mid frequency control to 400Hz and set the gain counterclockwise to cut until the desired amount is reached.
User Tip: As with the tone controls, it's recommended to set the Scoop control initially at the mid point. Adjust it slowly, either way, until the desired tone is achieved.
Tip: Combine the Scoop, the Distortion and Distortion Mix for unparalleled levels of tonal control. Set the Distortion and the Distortion Mix to their maximums and play your bass while slowly rotating the Scoop from its off position to its MAX position, you'll find the variation in the effect to be quite dramatic and yet very musical at the same time.
9. Effects Return Blend Control
Use the Effects Send jack to send a dry, uneffectcd signal to an external effects unit. The externally processed signal then can return to the amplifier through the Effects Rtn jack. The Effects Rtn blend control regulates how much of the effected signal is blended with the dry signal (un-effectcd signal). This can range from totally dry (without effects) to very wet (effects applied).
User Tip: If a wetter signal is desired, set the output signal from the external effects processor to a high output.
10. Bass Resonance Control
The Bass Resonance control adjusts the amount of low frequency damping of the amplifier. Turning the control clockwise towards Loose reduces the damping factor and allows the resonance of the speaker cabinet to be more pronounced. Setting the control towards Tight increases the damping factor to achieve a punchier sound.
11. Selectable Limiter
In order to prevent hard clipping of the power amplifier, a selectable limiter is provided.
12 Master Volume Control
The Master volume control adjusts the overall signal level of the amplifier.
13. Protect LED
The red Protect LED displays the status of the internal protection circuitry. When the DynaBass 800H is initially powered up internal protection circuits are activated, no output will be heard until the red Protect LED automatically shuts off. In a rare case of amplifier shutdown or if the output is shorted, the amplifier will take approximately 15-20 seconds to reinitialize and obtain full power.
14. Power
The LED above the Power switch will illuminate when the unit is on
15. Mute Switch
The Mute switch disengages the preamp signal from the Line Out and power amplifier, disabling signals sent to the mixing console and speaker cabinets. The Tuner Out jack is still enabled (see Tuner Out in the Rear Panel section).
Rear Panel
16. Dual Footswitch Jack (Distortion and EFX-Return)
A dual footswitch jack can be used to switch the Distortion and the external Effects on and off.
The footswitch uses a standard TRS 14 -inch based dual footswitch (AFS-2). When either effect is activated, corresponding LED's on the amplifier will illuminate and off (and on the footswitch as well). The Effects are only switchable by the footswitch, but the Distortion can be enabled or disabled by either the footswitch or the switch located on the front panel. The footswitch control overrides the front panel switches.
17. Tuner
The Tuner out 14 -inch jack sends the signal from your bass guitar to an outboard instrument tuner. Simply connect one end of a 14 -inch shielded cable to the Tuner Out jack and the other to the instrument tuner. Pressing in the Mute button will mute the output to the speakers as well as to the line out, but not the Tuner out.
Tip: Leave your tuner connected to the Tuner Out jack and Mute the signal any time you wish to tune in silence. A very handy feature when onstage and the unpleasant sound of tuning is not something you wish the audience to hear amplified through your performance speakers or the sound system.
18. XLR Line Out Jack
This jack is used to connect directly to mixing consoles. You may prefer to use this when performing live or recording in the studio.
Selecting the Pre-EQ option in the Line Out mode selection switch (located on the front panel) makes the Line Out behave like a typical D.I. box: it provides a pre-EQ and pre-EFX signal. The Post-EQ option sends the signal post-EQ and post-EFX, which enables the output to drive another amplifier or the mixing console.
Note: When the Mute switch is engaged, a signal will not be sent to the mixing console through the XLR output.
19. Ground Lift Switch
The Ground Lift switch is located next to the balanced Line Out XLR on the rear panel. If hum is detected, when connecting from the balanced Line Out XLR to a mixing console (or any other audio device), lift the ground (pin 1) by pressing the Ground Lift switch in.
20. Amp In 1/4 -inch Jack
The balanced Amp In jack is located on the rear panel of the DynaBass 800H. The Amp In jack provides a direct path to the DynaBass 800H's power amplifier, bypassing the preamp. The Master control still controls the overall output level. Multiple DynaBass 800H's can be linked together by using the DynaBass 800H's balanced XLR Line Out to additional DynaBass 800H Amp In jacks.
Balanced 1/4-inch T.R.S. to Balanced XLR
21. Effects Send and Return 14 -inch Jacks
External effects processors are provided with a balanced post-EQ signal from the Effect Send jack. The balanced Return jack is used to return effects (processed audio signals) back into the DynaBass 800H. The Effects Return control, located on the front panel, regulates the blend of effected and un-effected signal. This input can also be used as an auxiliary input for mixing in a secondary source of audio such as pre-recorded music.
User Note: The Effects Send jack can also be used as additional line out for sending signals to another power amplifier. The output of this jack is not muted when the Mute switch is enabled.
22. Output Jacks
The 1/4 -inch and Speakon™ jacks are used to connect extension speaker cabinets. All speaker output jacks are in connected in parallel; the minimum load impedance is 2-ohms (e.g. two 4-ohm or four 8-ohm cabinets).
23. Circuit Breaker
In the event the DynaBass 800H amplifier draws excessive electrical current from the wall receptacle, the circuit breaker will trip to cut power to the unit and prevent further damage from occurring. Once the amplifier has cooled, the breaker may be reset to re-enable operation. If the amplifier's circuit breaker continues to trip, please have the DynaBass 800H inspected by a qualified service technician.
24. AC Power Receptacle
The DynaBass 800H is equipped with a standard grounded IEC power receptacle. Only use the supplied removable power cord or one that uses a minimum of 16 gauge wire.
25. Cooling system
Two 3-inch fans cool the DynaBass 800H. The fans are run at low speed and the speed self-adjusts depending on how hard the amplifier is working. The air intake vents are located at the rear of the amplifier and on the top (near the back). The exhaust vents are located at the sides.
Caution: The rear vent must be kept clear in order for the air to enter into the amplifier. The side vents are used to allow warm air out of the unit. Allow at least an inch clearance for each side. Always keep the rear of the unit unobstructed. Rack-mounting the DynaBass 800H chassis will not affect intake/exhaust airflow as long as the rear of the rack casing is open during operation and 1 inch of clearance along the sides is unobstructed.
26. Preamp Tube Replacement
Use only Yorkville Sound part number "12AX7SORTED" when replacing preamplifier tubes as they have been specifically selected for this product. Please refer to the Service Manual for more information.
