ZXM500.4 – Class-D 4-Channel Mini Amplifier
The ZXM500.4 is a compact Class-D 4-channel amplifier designed to deliver solid power in a small footprint. The ZXM series focuses on minimizing size without giving up output strength, clarity, or essential features. This model provides 500W RMS total power, giving you 4 x 80W RMS at 4Ω. It also operates safely at 2Ω, where it delivers 4 x 125W RMS, and the channels can be bridged for 2 x 250W RMS at 4Ω. The unit includes adjustable high-pass and low-pass filters, along with a switchable 2-channel or 4-channel input option for both low- and high-level signals.
The amplifier is engineered to keep electromagnetic interference low, helping prevent issues with modern vehicle electronics and maintaining clean FM reception.
