HH Electronics SR1500 Power Amplifier
The HH Scalar series of amplifiers are the perfect complement to any passive PA cabinets, whether monitors, front of house or subwoofers.
Efficient, lightweight switch-mode power supplies and high quality Class H amplification circuitry ensure perfect sound and effortless power from surprisingly light and compact amplifiers, whilst still maintaining impressive bass response.
Styled with a nod to our much respected amplifier heritage, these are nonetheless thoroughly modern high performance amplifiers with all the flexibility, performance and reliability required for today's live music scene.
Although only 11kg, the SR1500 provides 750W RMS into 4 Ohms from each amplifier, and 1500W into 8 ohms when bridged.
To ensure reliability and safety, a Neutrik Powercon connector is used for the mains.
The increased headroom and power make this a perfect partner for larger cabs and bigger venues.
