نظرة عامة

The cure for an overworked receiver.

This three-channel power amplifier takes over the hardest job in most systems, driving your left, center, and right speakers so your AVR can focus on processing and switching instead of struggling for power.

Connect it to an AV processor, stereo preamp, or any AVR with AVR preamp outputs (usually labeled PRE OUT) using RCA or balanced XLR inputs. A smooth Class A/B amplifier output stage and heavy-duty linear power supply with an oversized toroidal transformer deliver clean, low-noise performance with confident speaker control, while microprocessor monitoring and transparent protection help keep everything safe and drama-free. Add 12V trigger in/out for easy power sequencing, and enjoy the peace of mind of a 3-year warranty.

Common uses:

• Power the front LCR in a surround system for clearer dialogue and steadier imaging

•Take the strain off an AVR by offloading the three most demanding channels

•Build a clean, punchy 3.1 system with dedicated amplification

Want a quick check that your receiver has PRE OUTs, or help choosing RCA vs XLR? Contact us, we're real humans who will help you get it right.

المزايا

Smooth Class A/B Sound
This three-channel Class A/B amplifier is designed to sound smooth, detailed, and natural, with stable imaging and no added harshness. A low-noise, wide-bandwidth design and optimized input stage help you hear more from your sources..
Heavy-Duty Linear Power
A heavy-duty linear power supply with an oversized toroidal transformer delivers plenty of current for real-world speakers. The goal is simple: consistent, confident performance when your system gets demanding.
Built for Real-World Reliability
Quality parts, robust construction, and double-sided FR4 circuit boards with plated-through holes help optimize signal paths and long-term durability. The heavy steel chassis with a milled aluminum faceplate adds strength and a clean, classic look.
Easy System Integration
Connect to an AV processor, stereo preamp, or any AVR with preamp outputs using either balanced XLR inputs or unbalanced RCA inputs, one per channel. 12V trigger input and output make it easy to power on and off with the rest of a home theater system.
Transparent Protection
Microprocessor-controlled monitoring and protection are designed to be transparent during normal listening, while guarding against common fault conditions. Backed by a full 3-year warranty for peace of mind.
