Schertler JAM [200] G & W

Formerly known as SR Technology, Schertler's JAM line of amplifiers offer musicians a cost-effective, all-round solution for portable acoustic amplification.    JAM [200] becomes the third member of Schertler’s “next generation” acoustic amplification series. The new 5-channel “all-rounder” combines a comprehensive feature set with the updated technology and enhanced “look” that defines all the models in this latest range.

Equipped with a 1” dome tweeter and 8” woofer, and featuring an optimized 2-way bass reflex construction, JAM offers 200W (150W + 50W) of bi-amplified power. The amplifier includes a balanced microphone (XLR) input, an unbalanced mic/instrument input and an input offering both balanced microphone and unbalanced mic/instrument options. Both instrument inputs feature a Bootstrap technology that enables the input to automatically adapt to any impedance. A separate stereo input channel will additionally accommodate devices such as a computers, MP3 or CD/DVD players. A 5th FX Return channel can also be used for inputting line level devices.

The 3 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 additionallyequipped with a phase reverse switch to prevent feedback, or unwanted effects between the various channels.

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. JAM is additionally equipped with a high voltage CLASS-A preamp that has no integrated circuits and No Negative Feedback (NFB).

Amplifiers are available in a choice of wood or anthracite finishes. The more delicate wood finish is perfect for studio or home use, blending with a range of room interiors. The anthracite finish is designed for performance and touring applications, where a more robust exterior finish is required.
