I bought this for an Allen & Heath CQ18T and it is a great case for it. I can put the power supply in beside the mixer too. I always keep bits of foam etc for padding out cases and just use a bit to cover the barrel of the supply to make sure it doesn't make contact with screen during transit. Case is watertight and very durable , with good handle and catches. Very robust indeed. I wil be buying more of these now that I know the quality.
