MOD SERIES LINER POWER SUPPLY AMPLIFIERS

To ensure a transparent and sonically neutral audio experience, the MOD series has been painstakingly innovated. Constant up-gradation in technology in the pro-audio industry has resulted in the creation of new technologies and improved amplifier performance through efficient circuits and components. The MOD is one of the first pro-audio amplifiers in the world to use Silicon Carbide Mosfets [SICMOS], which have ex tremely low switching loss and result in highly efficient amplifiers with large dynamic headroom.

DESIGN PHILOSOPHY

• Sonic performance
• Ease Of Service
• Reliability

The MOD Series is a hybrid of linear power supplies and high-efficiency Class-D output stages. The PCBs are modular in assembly, and on-field replacements are as simple as unscrewing a few fasteners, dropping in a new PCB, and you're back in business.

AMPLIFIER TOPOLOGY

The Class-D output stages employ a post-filter feedback topology with nd a 2 order active integrator and dual feedback loops to achieve low output stage impedance and damping factors in excess of 1500. The output uses Silicon Carbide Mosfets, which are powered by dedicated isolated drivers with low parasitic capacitance floating power supplies. The output inductors use Triple Stacked Cores for substantial headroom before reaching any saturation current limitations.

AMPLIFIERS WITH LINEAR POWER SUPPLY

The high current toroidal transformer, in conjunction with dual bridge rectifiers, connects the large capacitor bank as an instantaneous power reservoir for fast current dispersion at sustained load.

PROTECTION

The amplifier has a sophisticated set of protections. When the amplifier detects an over current or output voltage limitation during clipping, the limiter-based automatic gain reduction activates, rapidly reducing the drive signal and keeping the output stage in a safe operating area. The main protection circuit has some great features for countries, where power grids are erratic and unreliable. The CSC amplifier protection circuitry monitors the main AC voltage and automatically shuts down if it exceeds 270 volts. The amp can easily sustain voltages of up to 440 VAC.

SAFETY INSTRUCTIONS

• Do not use this product near rain or water.
• Only use a dry cloth for cleaning.
• Do not block the vents. Install it as per the manufacturer's instructions.
• Installing near heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat is not recommended.
• Do not defeat the safety purpose of the polarised or grounding-type plug. A polarised plug has two blades, one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide edge, or the third prong, is for your safety. If the provided plug does not fit into your outlet, consult an electrician to replace it with the appropriate plug.
• Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the unit.
• Unplug the unit during lightning storms or when unused for long periods.
• Refer all service requests to qualified service personnel. Servicing is required periodically and when the unit is damaged, either mechanically or electrically, or is used in a smoky or dusty environment.
• Use the mains plug to disconnect the apparatus from the mains. Do not power the unit without servicing it when it has not been used for a long period of time or stored in a damp environment.
