You can drive any combination of 8 ohm and 4 ohm guitar cabinets from these
connectors. Be sure that the ohm selector switch matches the rating for the
connected cabinet. (You can, for example, connect an 8 Ohm cabinet to the left
and a 4 Ohm cabinet to the right.).

and a 4 Ohm cabinet to the right.).
Although the Signature 284 uses a low power design, it has plenty of power to
drive any 1 or 2 speaker guitar cabinet rated at 4 or 8 Ohms. (4x12 half-stacks
that can be split for stereo also sound great.) As the type of cabinet has a big
effect on the overall sound, you can create many different tonal voices by
changing cabinets. When using stereo effects, you will probably want to use
matched cabinets for the left and right speakers, but be sure to experiment with
using two different cabinets at once — a closed-back 10 and a open-back 12 can
sound great together.

The Signature 284 can be operated with either or both speakers disconnected.
Independent passive loads are connected automatically when no jack is
inserted into the speaker output.

The slave outputs carry post power amp signals attenuated to line level (+4dB,
unbalanced). Their primary purpose is to provide a means of getting more on-
stage volume for live use by driving a stereo slave power amplifier connected to
guitar cabinets. As these outputs are derived from the power amp outputs, they
carry the voice and tone of the whole amp — exactly as sent to the speakers.

Connect the inputs of any high quality power amp (solid state or tube) to these

outputs for a faithful (but louder) version of the Signature 284’s sound.
These outputs are post power amp signals attenuated down to line level (+4dB,
balanced) and run through a unique recording compensation circuit that
simulates the sound of two different speakers. The primary function of these
outputs is to provide a direct feed that is the sonic equivalent of a pair of well
miked speaker cabs to a PA system or a recording console. A separate switch,
provided for each recording output selects Smooth (think "4-12 cab”) or Bright
(think "2-10 cab”). A separate ground lift switch is provided for each recording
output.
