Rear panel features:
1. AC Power/Voltage Selector:
This amplifier can operate at AC currents of 100V, 110V, 120V, 230V. Simply remove the fuse with a small screwdriver, and line
up the correct voltage with the arrow, and plug back in. After selecting the correct voltage, connect the AC power cord the wall
socket.
2. MIDI IN/THRU:
These jacks allow the RT2-50 to be used with a any MIDI capable guitar preamp. The IN is the main input for the MIDI connection,
and The THRU passes the signal on to other MIDI capable units. When used with the RM4 or other MIDI guitar preamps, connect
the THRU of the RM4 or other preamp, to the IN of the RT2-50. See pages 9 & 10, for programming functions and uses.
3. Impedance select (Channel 1/2):
Set this switch to the correct ohm rating of your internal and external speaker cabinet. Make sure when using a combination of
speaker cabinets, that you select proper impedance, depending on the correct ohm ratings of the cabinet.
4. Main Inputs (Channel 1/2):
These are the main signal inputs. Connect a high quality 1/4 patch cable, for the output of the RM4 or other guitar preamp, to
the Channel 1 input. When using the channel switching mode, you must use channel 1 input first. In Switching mode, Channel 1
inputs controls Channel 1 and 2 outputs. When using Stereo mode, you can use Channel 1 and Channel 2 inputs.
5.
Switching/Stereo switch: The RT2-50 has 2 modes of operation, 100 watts of Stereo operation, and 50 watts per channel in
mono Switching mode. When assigning a specific channel to your guitar preamp, you must use Switching mode. Stereo mode can
be used for running multiple cabinets at the same time.
Tip : Switching mode can also be used with multiple cabinets, so you can
switch back and forth between cabinets. Simply connect to Channel 1 input of your RT2-50 from your guitar preamp, and in switch-
ing mode, run a speaker cable from both Channel 1 and Channel 2 outputs to different cabinets. This allows you to run different
sounds out of different cabinets and switch between them.
5. Main Outputs (Channel 1/2):
These are the main output, which is currently connected to your internal speakers. This can also be used as the main output for an
extension cabinet. YOU MUST USE THE MAIN OUTPUT FIRST.
5. Extension Outputs (Channel 1/2):
Used to connect to an external speaker cabinet. It is very important that you select the correct impedance when adding an extension
cabinet. EXTENSION OUTPUTS WILL NOT WORK UNLESS THE MAIN OUTPUT IS BEING USED!
