Dynamic, Clear Sound

The DEEP2 4950 produces the same dynamic, exceptionally clear sound signature that has earned the DEEP2 series its strong professional reputation — performing equally well across sub-bass applications and full-range multifunctional speaker systems. Its Class-H output circuitry with toroidal core transformer power supply delivers rated power of 4 x 810W at 4Ω and 4 x 490W at 8Ω, with 2 x 1600W available in bridged mono mode at 8Ω. With a damping factor exceeding 400, an SNR of 105dB and THD of less than 0.1%, the 4950 delivers the clean, controlled and authoritative sound that professional applications demand.

Comprehensive Protection & Control

Reliability is built into every aspect of the DEEP2 4950. A full suite of protection circuits — covering short circuit, DC protection and thermal overload — ensures both the amplifier and connected speakers are safeguarded at all times. Four individual channel volume controls, a ground lift switch, mains on/off switch and bridge/stereo mode selector provide straightforward, intuitive front panel operation, whilst LED indicators give clear real-time monitoring of signal, limit, power and protection circuit status. Automatic, highly efficient cooling maintains optimal operating temperatures throughout extended high-power use.

Robust, Road-Ready Construction

Despite its impressive four-channel power output, the DEEP2 4950 remains a practical and manageable unit at 19.6kg, housed in a robust steel plate chassis with a compact, user-friendly design. Speakon-compatible speaker outputs on the rear panel provide secure, professional-grade connections, completing a package that is equally at home on a touring rig or in a fixed installation rack.
