KRM 7003+

Professional Power Amplifiers


• Excellent audio performance
• State of the art technology provides exceptional reliability when working with up to
2 ohm impedance
• Excellent handling of low frequencies as well as clear mid and highs
• Optimized power supplies, filter and heat sinks for better low end, transparency
and stability

turn-on delay) with high current speakers protection relays.
• Flexible input configuration with active balanced inputs, additional input connectors
for easy signal jump.
• True clip LEDs for better control
• Front-to-Rear airflow with 2speed fan control
• Efficient heat sink design for thermal stability and reliability
• Turn-on in-rush current limiting circuitry
• Steel reinforced chassis construction for durability and longevity.



KRM amplifiers are very-high-quality power amplifiers designed to elicit maximum performance from any speaker system. Their ultralow distortion and powerful amplifiers ensure that program material will be amplified very accurately. Their superior design and build quality makes them extremely reliable against over-temperatures, radio frequency interference, shorted outputs, spike on power lines and DC faults.


They have been given a vote of confidence by high end audio users around India because of their intense reliability, high level sound and durable design. All KRM amps are geared with unmatched and complete protection and safety package for maximum performance.


KRM amplifiers have sophisticated protection circuits that guard it and the load from problems. Protection circuits guard against overload, over-temperature, shorted outputs, radio-frequency interference and dc faults. The output devices are protected against damage from reverse feeding of electrical energy (back EMF) and are switched on via relays to avoid transients which could damage speakers.


Possible to exchange amplifiers of different power ratings without upsetting delivered sound pressure levels or spectral balances. KRM amplifiers are the choice for serious, professional amplification applications which require optimum sound quality, speaker protection, and the highest level of construction quality and long-term reliability.

• Auditorium
• Club sound
• Portable Dj systems
