Depending on the model, JBL amplifiers support low-impedance speaker loads at four or eight ohms, along with 70V or 100V distributed audio systems. This lets integrators use direct speaker connections for conventional setups or distributed-voltage outputs for connecting multiple commercial speakers across a larger area.

JBL power amplifiers provide amplification for an external audio source, with one or two output channels and support for low-impedance or 70V and 100V distributed audio systems, depending on the model. Mixer-amplifiers combine multiple mic and line inputs, mixing controls, and power amplification in one chassis, which helps support background music, paging, and other commercial audio applications.

Choose the number of channels based on how many independent speaker zones or audio signals you need to control, with one-channel and two-channel options represented across these JBL amplifiers. Select output power by totaling the connected speakers’ power requirements, allowing practical headroom, and matching the amplifier to the system type, such as low-impedance speakers or 70V and 100V distributed audio.

Evaluate whether the amplifier supports the system’s speaker format, such as 70-volt or 100-volt distributed audio and low-impedance four- or eight-ohm loads, along with the required channel count and output level. Also review rack space, fanless operation, rack-mount hardware, input connections such as balanced mic or line and RCA, and RJ45 connectivity for compatible remote volume controls.
