REAR PANEL FEATURES
3. Slave Output Jack and Level Control
A SLAVE Output is provided to capture the entire sound (both preamp
and power section) of the amplifier so that it can feed an effects rack
or additional power amplifiers for big venue applications. This feed is a
padded-down version of the signal taken from the SPEAKER Output and
does not provide any roll-off of top end or other shaping that would be
preferable for using the Electra-Dyne direct into a recording console.
4. Speaker Impedance Selector Switch
SPEAKER IMPEDANCE is selected via this mini toggle and provides
for two 8 Ohm or two 4 Ohm jacks. Standard MESA cabinets are
either an 8 or 4 Ohm load. To use the ELECTRA-DYNE with 16 Ohm
loads, connect them using the 8 Ohm position. When using two 16
Ohm cabinets, also connect them to the 8 Ohm jacks.
5. Bias Select Toggle Switch
The Rear Panel BIAS SELECT allows you to swap the stock quartet of
6L6 for a quartet of brighter sounding EL34 type power tubes. This
classic British tube delivers greater accentuation of the upper harmonics and produces a low end this is somewhat stripped of sub-lows and
therefore can sound tighter for certain styles. Mesa/Boogie recommends the stock compliment of 6L6 for the greatest versatility and
warmth and all three Modes.
6. Footswitch Selector
EXTERNAL SWITCH jacks on the Rear Panel allow control of the
Modes from a remote master switching unit and respond to standard
¼" tip-to-ground latching logic. This feature allows for interfacing
the Electra-Dyne into a large stage rig where everything is called up
remotely under (usually midi) programs in a master switcher.
7. Reverb / Mode Defeat Mini Toggle Switch
With this mini toggle switch you can choose to use reverb in all three
Electra-Dyne modes (center “on” position) or you can engage an
auto-defeat feature that defeats reverb on either the vintage lo or vintage hi mode. It allows you to use reverb on just two of your sounds—
clean and your choice of lo or hi—so you can keep either your crunch
rhythm or lead sound dry while having your clean sound wet.
8. Reverb Level
Choose exactly how much of the Electra-Dyne’s rich, all-tube reverb
you’d like to add to your guitar tone.
9. Reverb On/Bypass Mini Toggle Switch
Hard bypass option that removes all reverb circuitry, including tube
stages, from the signal path.
