Heavy duty amp

Some features

• Hole mount components only
• Heavy duty design throughout
• Outputs 2x900WRMS at 2 ohm load +/-60V supply
• Analog inputs
• As all our amplifiers, audiophile sound quality
• High quality components
• Based on the Tripath TA3020 chip
• Supplies up to +/-60V

AMP7 is available in two versions

• AMP7
• AMP7-PS with integrated power supply (available later in 2009)

The AMP7 is designed for heavy duty loads, like PA, woofer amps and other applications that require high current drive capacity. Suitable for bridged outputs.

• Heavy duty design throughout
• Triple weigh (105um) copper layers
• 25 mm wide power and speaker traces, to carry very high currents
• 75A rated power MOSFETS
• Oversized output filters
• Mechanically stabilized inductors

The basic AMP7 has no on-board power supply. For a complete amp, you need to add a high current power supply, capable of driving your loads. Maximum +/-60V is recommended. You also need two independent housekeeping supplies, one for the onboard 5V, one for the gate drives. For the 5V, there is a 5V regulator on the AMP7 board, that needs to be powered, typically by 8 to 12V 50mA. The gate supply needs around 250mA, 10V, referenced 10V above the negative supply. For these two housekeeping powers, you can use PS2-P+P both set at 10V.

The PSU1-series supplies are also suitable:

PSU1-SS: Soft start and mains filter
PSU1-PS: rectifiers and bulk capacitors
PSU1-VR: Two voltage regulators for 5V and VN10
Note that the voltage regulator PSU1-VR, needs a separate transformer or similar moderate voltage supply.
