QSC SPA2-200 2-Channel 200W Power Amplifier

The SPA2-200 from QSC is a 2-channel, 200W power amp that delivers up to 200W per channel into Low-Z loads.

When two channels are bridged providing up to 400W rms into 4 or 8 ohms, they can be switched into 70V or 100V direct drive mode, providing up to 350 watts rms into a mono 70V or 100V output. Like the other SPA models, the SPA2-200 boasts an integrated 80Hz high-pass filter, which is engaged when in 70V or 100V mode.

QSC SPA2-200 Features

• Two-channel power amplifier
• Up to 200W per channel into 4 and 8 ohms - the outputs of the SPA2-200 model are designed to provide up to 200W per channel into Low-Z loads.
• ENERGY STAR® qualified amplifier - The ENERGY STAR qualified SPA amplifiers employ an efficient class-D design to conserve energy and reduce operational cost.
• Bridgeable outputs for higher power - Bridging the outputs of the SPA2-200 will deliver up to 350W into 70V or 100V when bridged.
• Auto-Ramp provides quiet startup and power-down - The ENERGY STAR auto-ramp circuitry ensures quiet and fast power up from standby and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
• Rack-mountable 1U, half rack width enclosure - The SPA amplifers can be mounted in 1 RU, 1/2 rack space, and their clever joining brackets enable easy under-table and wall-mounting

More about QSC’s SPA Power Amplifiers

These efficient power amplifiers deliver two or four channels of up to 200W per channel into 4Ω and 8Ω. Their outputs can be bridged for an extremely flexible solution for Low-Z or High-Z applications.

SPA power amps sport an advanced Class-D amplifier design and Universal Power Supply, allowing them to be convection-cooled, conserve energy, and reduce operational costs. All amplifiers in the SPA Series feature rms and thermal limiting, as well as protection against over current, short circuit, and under/over voltage.

They are also ENERGY STAR qualified, allowing for fast and quiet powering up from Standby, while the cutting-edge auto-ramp circuitry that transitions with no audible pops. SPA series amps automatically power down after 25 minutes of inactivity, which dramatically reduces power consumption.

The SPA Series are housed in an unobtrusive black painted 1/2 RU chassis. They can be mounted in 1RU, ½ wide rackspace, and include all the hardware you need to mount it in a rack, under the table, or on the wall. The included connecting brackets provide additional sturdiness when mounting two amps together. The SPA Series is also compatible with mounting in plenum spaces when using the Plenum Kit accessory (sold separately).
