Project Title: 60W,120W,240W Class D amplifer,1000W Booster amplifer.

Description: The portable mixer amplifier is a professional public address unit with modern state‑of‑the‑art features, which is built on class-D platform. The amplifier is easy to use, taking the complexity away from the user and putting it where it belongs, inside the equipment. Providing a crisp call or clear music is as easy as turning on a radio. Offering the essentials of public address in an affordable package.

Power Amplifier Variant) Integral part of team from A to D Sample.

Board bring-up for checking Component orientation, verifying DNI Components & Impedance check on PCB.

Performance Validation of Class -D amplifier for parameters like Input sensitivity,

O/p Voltage, THD, SNR, CMRR & Frequency Response. This was tested for all Mics,

Lines, Aux, BT, USB Modes. (with 4Ohm O/p & 100V O/P)

Automation of APx500 software used for performance monitoring of amplifier.

Project Title: Low Power Ultra high frequency portable (LUP) 329 Radio
