The SPA4-60 four channel amplifier delivers 60 watts RMS per channel into 4 or 8 ohms; the channels can also be bridged providing up to 200 watts RMS into 4 or 8 ohms per channel pair. The bridged channels can be switched into 70V or 100V direct drive mode providing up to 250 watts RMS into a 70V or 100V output. An 80Hz high pass filter is engaged when in 70V or 100V mode ensuring that distributed loudspeaker transformers are not overdriven and saturated by too much low-frequency content.
Efficient Amplifier with Auto-Ramp: The SPA Series amplifiers utilize a highly efficient class-D design that conserves energy to reduce operational costs and requires no active cooling. They are ENERGY STAR qualified with auto-ramp circuitry that seamlessly transitions to/from Standby with no audible pops.
Amplifier Protection: Both amplifiers in the SPA Series feature rms and thermal limiting, as well as protection against over current, short circuit, and under/ over voltage.
Protection, Control and Mounting: The SPA Series provide rms and thermal limiting as well as over-current and short circuit protection so you can employ them with confidence. They also come with multiple mounting options. Every SPA Series comes with a complete mounting kit allowing it to be rack mounted by itself or with a second unit in a 1RU space. Included connecting brackets provide additional strength when rack mounting two amps together, but also make for simple under-table or wall mounting (like behind a TV). The SPA Series can also be mounted in plenum spaces when used with the Plenum Kit accessory.
