Tilman Ritter Camplifier 90 User Manual page 5

Only connect the device when the power switch is off.
Never connect the inputs or outputs to any power source (batteries, etc.)
Never connect output to output.
Before the device is switched on all faders and volume controls have to be set to "0" or "min" position.
Never connect the Speaker OUT of the CAMPLIFIER 290 to the signal OUT of the Kemper Profil-
ing Amplifier!!
This would cause damage to the Kemper Profiling Amplifiers and the CAMPLIFIER 290!
