The Schertler Jam Acoustic Guitar Amplifier Combo Anthracite is a 5-channel model featuring a 200W bi-amplified design, an 8" woofer, a 1" tweeter, a plywood cabinet, and an anthracite finish. The three main microphone/instrument input channels include a Gain control for input sensitivity regulation and 3-band EQ, with parametric mids on input channels 1 and 3 and a switchable resonance (notch) filter (240Hz/150Hz) on channel 2. Phantom power is supplied for condenser and electrostatic microphones. Each of these channels also features an overload LED. Channel 1 is additionally equipped with a phase reverse switch to prevent feedback, or unwanted effects between the various channels.
The Jam’s Master Section controls include a new adjustable DI Out, a new Mute button, a Line Out enabling the connection of externalsystems, a digital reverb and an Insert for connecting an external dynamics processor. Connection options are further enhanced with an Aux Out (Channel 1) that also enables connection to other systems. A Low Cut filter (cutting frequencies below 180Hz) can be used with instruments that generate aggressive low frequencies. This also enables a separate subwoofer to be connected without causing any damage to the amplifier. The Jam is also equipped with a high voltage CLASS-A preamp that has no integrated circuits and No Negative Feedback (NFB).
