Two amp setup for soloing
There are two primary reasons for switching amps on stage. The most
common is for artists that want to radically change their tone such as
going from a clean ‘Fender
®
’ to a distorted ‘Marshall
®
’ to add crunch or
maybe for soloing.
Two amp setup for backup
The second is to provide the artist on stage with a backup. Should one
amp fail, the technician can quickly select the backup amp without having
to reconnect wires half way through a show.
Switching between amps may be done by either using the front panel
AB selector switch or by adding the JR-2 remote control footswitch. To
eliminate hum and buzz caused by ground loops output B is transformer
isolated. It is important to note that only one amp can be active at any
one time.
Switching channels may also be done using the optional JR-2 remote
footswitch (part no. R800 2090). This compact device features two
footswitches: the first is an AB SELECT switch with two LED status
indicators and the second a MUTE with another LED. The LEDs are
remotely powered via the ¼” TRS remote connection on the JX-42 thus
eliminating the need for batteries. With a JR-2, you can use either a ¼”
TRS to TRS or a TRS to XLR-F cable. To switch channels, make sure
the JR-2 is connected properly. One of the LED indicators will illuminate
to let you know if power is being received. Simply depress the footswitch
to select the active amp.
