Product Description
The ZED 4-Buses series are inspired from a number of different products in the A&H line range that, by combining them with new ideas have achieved astounding stylish results in an easy to use package.
The new designed DuoPre mic/line pre-amplifier which was first fitted on the ZED-14 delivers a high-headroom, low-noise signal. From the renowned GL2400 come the 4 band, 2 sweep EQ plus the low noise summing amps, where as the simplified, but equally effective, bus architecture is a version of the one used in the GL series.
The ZED-420 has a unique flexible capability through its USB audio interface by allowing different signals to be sent to USB, either from LR or selected aux buses, while the return signal from the USB may be routed directly to the LR mix or to a stereo channel. The connectors have been placed on the top surface for easy connection. With the circuitry boards strongly held to the top panel and its rugged construction make the ZED-240 as strong as A&H top of the range ML Series mixers.
