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 ¼-inch based dual footswitch (AFS-2). When either
effect is activated, corresponding LED's on the amplifier will illuminate on 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 ¼-inch jack sends the signal from your bass guitar to an outboard instrument
tuner. Simply connect one end of a ¼-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 ¼ -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.
