Product Description
Allen & Heath AH-ZED24 Analog Mixer with USB Connection
ZED-24 has an incredibly advanced feature-set for a mixer at this level – it has 23 independent sources to the mix, 10 independent outputs, 4 aux sends, Configurable USB audio in/out makes it easy to capture stereo recordings, playback and effects, a unique dual stereo input capability and some very advanced monitoring facilities. In fact, ZED-24 is so packed full of great features that you’d think it would cost much, much more!
Based on the proven pre-amps from the hugely successful PA series, ZED-24 has DuoPre pre-amps, which use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the XLR input, the gain range is huge – 69dB of range to be exact – and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. Line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket, which has the great advantage of less noise when using the line input and also matching to a higher input impedance.
