The Cloud Electronics CX163 two zone stereo pre amp mixer providing six stereo line level inputs and one microphone input. It's ideal for sound systems for pubs, bars, shops and leisure venues & is one of our favourite products.

The Cloud CX163 has 2 stereo zone outputs and 1 mono utility output (ideal for utility areas such as toilets and foyers). Music level can be controlled remotely by the RL-1 (see related products) on both stereo zones and when operating in mono, each zone can be split into two sub-zones each with its own remote level control (RL-1).

Once installed this compact 1U rack mounted 2 zone mixer is extremely simple and convenient to operate.
