Skytec SPL400 - 2x200W Stereo Amplifier with Limiter and RCA Inputs (19”, 2U)

The Skytec SPL400 is a compact and reliable stereo power amplifier for DJ booths, venues and small installations. It delivers 2x200W max per channel into 4Ω (up to 2x150W max into 8Ω ), with independent volume control per channel , clip indicator and peak limiter to protect your speakers. It incorporates stereo RCA inputs and speaker terminal outputs , and offers a frequency response of 20Hz to 20kHz with THD+N <0.5% , signal-to-noise ratio >95dB and crosstalk >82dB . Its 19” (2U) rack-mount chassis with dimensions of 482x270x88mm and an approximate weight of 4kg , ideal for flightcases and standard racks.

Main features

• Max power : 2×200 W @ 4 Ω per channel / 2×150 W @ 8 Ω per channel.
• Equalization from the source : compatible with tables, players and TVs via stereo RCA .
• Practical protections : peak limiter and clipping indicator to prevent saturations.
• Easy connectivity : RCA inputs and outputs via screw terminals (bare wire).
• Clean audio : 20 Hz–20 kHz, THD+N <0.5% , S/N >95 dB , crosstalk >82 dB .
• Professional format : 19” (2U) ; easy to integrate into racks and flight cases.
• Universal power supply : 220–240 VAC, 50 Hz; minimum load 4 Ω per channel.

Product benefits

• Quick and easy to use : select source via RCA and control level per channel.
• System protection thanks to the limiter and signal/clip indicators.
• Versatility for pubs, classrooms, gyms or mobile events with 4–8 Ω passive speakers.
• 19” (2U) format that saves space and organizes rack wiring.

Use cases

• DJ booths and basic sound reinforcement in venues.
• Fixed installations with multiple analog sources (TV, CD/DVD, tuner, mixer).
• Mobile sound in 19” flightcase.

Compatibility and connections

Connect RCA sources and speakers to the terminals, respecting the minimum impedance of 4 Ω per channel. Adjust the input levels (line sensitivity 0.775–1.2 V ) to prevent the clip LED from remaining lit. Use speaker cable of the appropriate cross-section (e.g., 2x2.5 mm² for medium lengths) and allow for ventilation around the equipment.

Frequently Asked Questions

• Does it have Bluetooth or USB? No. It's an analog amplifier with RCA inputs.
• Does it support 2 Ω? No. The minimum load per channel is 4 Ω .
• How do you connect the speakers? Use bare wire terminals ; press firmly for good contact.
