BACK PANEL (continued)
Speaker Impedance
On a combo this rotary selector knob comes set at 8 ohms for a single 12 or 4 ohms for a 2x12.
The selector knob can select between 4, 8 and 16 ohms. Check Ohm’s Law if using an additional
extension cabinet to select the right ohm setting. Example: 8 ohms + 8 ohms = 4 ohm setting.
On a head, please be sure to select the proper ohms to match your cabinet.
Footswitch and Jack
The sturdy footswitch included with the Hot Cat 30R amp plugs into a jack located underneath
the chassis on the far left when viewed from the back. Please assure that the footswitch jack is
firmly connected to the amp’s jack before operation. When the footswitch is connected, the clean
input is the active input for switch channels via the footswitch. As for the footswitch, the button
on the left selects either channel while the button on the right adds the other channel no matter
which channel you’re on.
TROUBLE SHOOTING
Your new Bad Cat amplifier designed for many years of professional trouble free operation.
Common sense will tell you that if you notice any sever abnormalities in operation like burning
smell, smoke, etc.; you need to shut down the amp
immediately.
Always consult your Bad Cat
dealer if you are unsure of the problems that you are dealing with; i.e., take your amp to where
you purchased it.
No Power
Check the power source from the wall first. Make sure the power cord is properly seated at both
ends. If there is still no power, check the fuse and replace if necessary with the correct rating
Weak Output Level
Verify the signal output from your instrument first. Check guitar’s controls and that the cables
are working properly. Also, check any effects pedals that may be connected in between the guitar
and the amplifier.
Adverse Sounds-Hum, Whistle, Loss of Dynamics, Feedback, Howling
Check loudspeaker cones, frayed guitar cables, controls on your instrument, the guitar’s pickups
and any other devices that many be connected to your amplifier such as effects pedals or rack
processors. Some of these devices are “amplifiers” in their own right with gain and boosted
volume levels and they may cause hissing and unwanted feedback if set too high in front of the
amp.
