Swiss manufacturer Schertler has announced the release of JAM, the third member of its “next generation” acoustic amplifier series.
Representing an evolution of the company’s JAM 150 amplifier, this new 5-channel 'all-rounder' offers greater flexibility in both live performance and studio situations. The amp combines a comprehensive feature set with the updated technology and enhanced 'look' that is characteristic of all the models in this series.
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 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.
JAM’s Master Section controls include a new adjustable DI Out, a new Mute button, a Line Out enabling the connection of external systems, a digital reverb and an Insert for connecting an external dynamics processor. An Aux Out (on Channel 1) offers additional connectivity 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).
A choice of wood or anthracite grey finishes is available. Models with the wood finish have a textile front speaker cover, making them well suited to normal domestic/home/club use where they can integrate with a range of interiors or design stages in live music clubs. Models with the anthracite grey finish are equipped with a metal front grille. These have been designed for more robust stage and road use, where there is greater exposure to daily wear and tear or to potential damage during transportation.
