It’s important to note that all top control panel knobs except Master Volume (H) are, as described above,
“programmable.” That means that when a preset is rst selected, the physical position of a top control panel
knob may not indicate the actual setting contained in that preset (the actual setting appears in the display
window). Only the Master Volume control is not programmable—its physical position always indicates actual
overall volume. Once a programmable top control panel knob is turned, however, it and its digital counter-
part within a preset become synchronized to the same value, as illustrated here:
Also note that an adjusted control knob setting can be saved in a new preset, or the original preset can be
overridden with the adjusted control knob setting. If the adjusted setting is not saved, the preset will revert
to its pre-programmed control knob settings when returning to the preset after leaving it, or when turning
the amplier o and back on again (see further info under “Editing and Saving Presets,” pages 10-13).
REAR PANEL
L. POWER: Turns amplier on and o. When rst switched on, Rumble Studio 40 and Rumble Stage 800
both have a typical start-up-sequence time of 15 seconds before the rst preset appears in the DISPLAY
WINDOW (G).
For Rumble Stage 800 only, when quickly turning the power o and then on again (as during a WiFi up-
date), a brief delay can occur during which the DISPLAY WINDOW will remain blank for 20-30 seconds.
This is normal in some high-powered ampliers such as this one, and the startup sequence will resume
with no need to cycle the power switch again.
M. IEC POWER INLET: Using the included power cord, connect to a grounded outlet in accordance with the
INPUT POWER voltage and frequency specied at the power inlet.
N. EXTERNAL SPEAKER OUTPUT AND IMPEDANCE SWITCH (RUMBLE STAGE ONLY): Connect an exter-
nal speaker cabinet here (8Ω or 4Ω minimum impedance); combination jack works with Speakon® or 1/4”
speaker cable. Set switch to match impedance rating of external cabinet; continuous power rating of
external cabinet must meet or exceed power rating listed for the chosen switch setting. Set switch to 8Ω
when no external cabinet is connected.
O. HORN SWITCH: Turns high-frequency horn on and o.
Rumble Stage 800 rear panel shown; Rumble Studio 40 rear panel has same features except for external speaker output and impedance switch (N).
