NOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or a
feedback loop will occur. Much like holding a microphone into the PA system’s cabinets...a loud high pitched
squeal will occur.
SPEAKERS: Two 8, two 4 and one 16 Ohm jack are provided for speaker interfacing. The TREM-O-VERB is not very sensitive to
speaker mismatches and will not be damaged by them, except that very low ohmage loads will cause the power tubes to wear faster.
A single twelve-inch 8 Ohm speaker should generally be connected to the 8 Ohm output. When using two 8 Ohm speakers, connect
them both to the 4 Ohm outputs provided (because the total load is 4 Ohms in that case.) If you have the TREM-O-VERB Combo,
your two 16 Ohm speakers are wired in parallel producing an 8 Ohm load.
4x12 cabinets may be 4, 8 or 16 Ohms. If you are not sure of the impedance of
your cabinet, you may need to remove the rear panel in order to verify the imped-
ance rating of the individual speaker or speakers. Mesa/Boogie 4x12 and 4x10
cabinets come standard wired to 8 Ohms, and are wired in series-parallel. Some
Non-Mesa 4x12 cabinets are wired 16 Ohms using four 16 Ohm speakers. By
wiring all four speakers in parallel, you can reduce the cabinet to an impedance
load of 4 Ohms (assuming the speakers are 16 Ohms each.) No matter how
unusual your speaker setup, it is always possible to get good performance.
EXTERNAL SWITCHING JACKS: These jacks allow ( usually MIDI-programmed ) operation of your amplifier’s functions from an
external switching source. In either case, the switching is accomplished by connecting ( “shorting” ) the jack’s “Tip” to its “Ring” (or
ground.)
CHANNEL CLONING
(TM): This circuit (patented) makes possible a concept, so inherently right, that in it’s simplicity it was long
overlooked. To be able to set a group of controls in a given channel of a two channel amplifier - to duplicate that channel and that
control setting, (save for maybe one or two controls,) in another separate channel of that same amplifier. Sounds’ simple? Well it
would be, but most, if not all amplifiers, must use the available internal space to offer circuitry and front panel real estate for alternate
channels that vary greatly in both gain structure and tonality.
CHANNEL CLONING
(TM) is our answer to this channel expanding idea. By providing two identical groups of front panel controls and
interfacing each of them to it’s own different and dedicated channel, we achieve the VINTAGE ORANGE
and MODERN RED channels. Sophisticated internal switching circuitry then enables you, the user, to
utilize the channels for their differences - “Normal” or; with a flick of the switch - Clone them “ORANGE to
MODERN” or “RED to VINTAGE.” This allows for virtually any combination of your two favorite sounds to
be footswitchably possible even if they are normally found in the same channel! CHANNEL CLONING
greatly enhances the versatility of the TREM-O-VERB live or in the studio, while retaining its clean
front panel layout.
NOTE: When the CHANNEL CLONING
(TM) feature is used and the MODERN RED channel is cloning RED to VINTAGE (so that it
sounds like the ORANGE channel) - be aware that both the ORANGE and RED channels’ PRESENCE Controls are active in the
(bottom) RED channel in this setting only. Some amazing sounds are possible because the two
PRESENCE Controls maintain their respective voicing differences giving you two regions of top
end harmonics to play with in this mode.
CHANNEL SELECT SWITCH: This switch simply allows you to switch between the two channels
(VINTAGE /ORANGE and MODERN RED) without using the CHANNEL SELECT footswitch or,
when one is not available. To use the footswitch however, the CHANNEL SELECT switch must be
in the up (ORANGE) position.
