Power Amplifiers

Power amplifiers supply clean, high-current power to loudspeakers. In a home theatre, they are paired with an AV processor or an AV receiver's pre-outs to drive demanding speakers or add channels. In Hi-Fi, they work with a preamplifier to give more control and dynamics than an integrated amplifier. In commercial and live sound, they drive PA speakers, ceiling speakers and installation systems. We stock power amplifiers for home, studio and commercial use from brands such as Denon, Marantz, Rotel, JBL, DNM and Behringer.

Types of power amplifiers

• Stereo power amplifiers: two channels for Hi-Fi and front speakers in home theatre.
• Multichannel power amplifiers: five to eleven channels for home theatre with an AV processor.
• Monoblocks: one channel per chassis for maximum power and separation in high-end systems.
• Pro audio power amplifiers: rack-mount amplifiers with XLR inputs for live sound and installations.
• Commercial 70V/100V amplifiers: drive many ceiling speakers over long cable runs in shops, hotels and offices.

When do you need a power amplifier?

• Your speakers are hard to drive (low sensitivity or low impedance).
• You want more dynamics and headroom than your AV receiver provides.
• You are adding channels for Dolby Atmos beyond your receiver's built-in amplifiers.
• You run PA or commercial speakers from a mixer or DSP.

Specifications to check

• Power per channel: at 8 and 4 ohms (and 2 ohms for some pro amplifiers).
• Inputs: RCA for home use; XLR balanced for pro audio and long cable runs.
• Signal-to-noise ratio and distortion: lower noise and distortion mean cleaner sound.
• Damping factor: higher values give better bass control.
• Cooling: fan-cooled amplifiers suit racks; convection-cooled models are quieter for homes.
• Protection: short-circuit, thermal and DC protection for reliability.

Connecting a power amplifier

Connect your AV receiver's or processor's pre-outs to the amplifier inputs with quality RCA or XLR cables, then connect speakers to the amplifier. Set the receiver's internal amplifier for those channels to off or reassign it. Power on the source and preamp first, then the power amplifier; reverse the order when switching off.

Installation and ventilation

Power amplifiers generate heat. Provide good ventilation, especially in AV racks, and use rack fans if needed. Use the correct power cabling and avoid sharing sockets with heavy appliances.
