SP2600/SP4600

The SP2600 and SP4600 switch mode power amplifiers complete the non-powered sigma series line-array systems for the touring and corporate pro audio market.

Several trademarked systems are employed in the protection circuitry of the Sigma power amplifiers: CCL (Clever Clip Limiter), SP (Short-circuit Protection) and PCP (power chain protector). Collectively, they protect the amplifiers, relays and speakers in the event of failure and/or overload. These features, together with their rugged chassis construction and economical 2U rack displacement, make them first class touring amplifiers designed to withstand abuse.

An intuitive front panel provides fast and easy amplifier diagnostics. Balanced, analogue XLR inputs and passive-through outputs enable easy slaving of units.

Power ratings are as follows:

(Continuous Average Power)
SP2600 2x 1.300W @ 4 Ohms
SP4600 2x 2.300W @ 4 Ohms
