Slave Outputs

Recording Outputs

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.).

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.

Do NOT insert jacks into the rear panel speaker outputs

when using the amp without speakers.

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.
