The Magnitude3600 is a 2-channel power amplifier built for bands, venues, and sound engineers who need serious wattage to drive multiple speaker cabinets or power demanding loads. This rack-mountable amplifier delivers the clean power needed for mid to large-scale live sound applications.

With 1200 watts RMS per channel at 8 ohms, the Magnitude3600 provides the headroom necessary to drive PA speakers without distortion, even at high volumes. The amplifier scales up to 1800 watts per channel at 4 ohms or 2400 watts at 2 ohms, making it stable with lower-impedance loads that would cause lesser amplifiers to shut down.

The wide frequency response of 5Hz to 50kHz ensures full-range reproduction from subwoofers to horn-loaded speakers. THD+N below 0.05% and a damping factor greater than 400 maintain tight control over woofer movement for punchy bass response. The amplifier includes smart clip limiting and comprehensive protection circuits to prevent damage during demanding use.

This amplifier handles venues seating 200-500 people when paired with appropriate speakers, making it suitable for clubs, theaters, and outdoor events. Bridge mode delivers 3600 watts into 8 ohms for powering subwoofers or high-power main speakers.

Connect your mixing console via XLR inputs, with Speakon and binding post outputs for connecting to speaker cabinets. The unit requires standard speaker cables and fits in any 19-inch rack case at 2U height.

Seismic Audio backs the Magnitude3600 with professional support and ships nationwide. This amplifier delivers touring-grade power at a price point accessible to working musicians and venue operators.

Frequently Asked Questions

How many people can this amplifier handle for a live band setup?

The Magnitude3600 can power PA systems for venues holding 200-500 people, depending on your speakers and volume requirements. When paired with efficient 15-inch mains or line array elements, you'll have plenty of headroom for rock bands and high-energy performances. For smaller venues under 200 people, this amplifier provides significant reserve power for clean, distortion-free sound.

What cables do I need to connect this amplifier to my mixing board and speakers?

You'll need XLR cables to connect from your mixer's main outputs to the amplifier's inputs, plus Speakon or standard speaker cables from the amp outputs to your cabinets. The amplifier accepts both balanced and unbalanced signals, so you can use XLR-to-1/4-inch cables if needed. Make sure your speaker cables can handle the wattage you're running.

Can I use this amplifier to power subwoofers?

Yes, the Magnitude3600 works well for subwoofer applications, especially in bridge mode where it delivers 3600 watts into 8 ohms. This power level can drive dual 15-inch or 18-inch subwoofer configurations effectively. The low-frequency extension down to 5Hz and high damping factor provide tight bass control that subwoofers require.

Is this amplifier stable at 2 ohms for running multiple speaker cabinets?

The Magnitude3600 is designed to be stable at 2-ohm loads, delivering 2400 watts per channel at this impedance. This makes it suitable for parallel speaker connections or driving multiple cabinets per channel. The protection circuitry prevents thermal damage, though you should ensure adequate ventilation when running sustained high-power loads.

How does the bridge mode work and when should I use it?

Bridge mode combines both channels to deliver 3600 watts into a single 8-ohm load, perfect for powering high-wattage subwoofers or main speakers that need serious power. Use the rear panel switch to select bridge mode, then connect your load to the Channel A positive and Channel B positive outputs. This mode is ideal when you need maximum power for a single speaker rather than running two separate channels.
