Skytec SPL500EQ - 2x250W Stereo Amplifier with 3-Band EQ (19", 2U)

The Skytec SPL500EQ is a 2x250W at 4Ω stereo power amplifier with 3-band EQ , designed for DJ booths, venues and small installations. It incorporates multiple stereo RCA inputs on the rear panel for TV, CD/DVD players, tuners or mixers, and a 3.5mm front auxiliary input for portable sources. Operation is straightforward thanks to the input selector , signal and clip indicators and the blue LED lighting front panel . It offers 20Hz–20kHz passband , THD+N <0.05% , signal-to-noise ratio >95dB and crosstalk >82dB , with convection cooling (fanless) for quiet operation. It is rack mountable in a 19” (2U) and features a compact chassis of 482x290x88mm .

Use cases

• DJ booths in bars and small venues with 4–8 Ω passive speakers.
• Fixed installations (classrooms, gyms, social centers) with several analog sources.
• Mobile events in a 19” flight case .

Compatibility and connections

Connect RCA or 3.5 mm sources and speakers to the terminals . Keep the impedance per channel ≥ 4 Ω . Adjust levels to prevent the clip LED from lighting continuously. Use speaker cabling appropriate for power and length (e.g., 2x2.5 mm² for medium runs).
