The Knoll Q450 is a four-source (inputs) and four-zone (outputs) audio amplifier for multi-room audio distribution that’s controllable via keypads a browser or an iOS or Android phone. It’s spec’d to use less than a single watt in standby mode and uses Knoll’s Eco-System.
Each of the four zones or rooms can select any of the four inputs, with individual volume control, bass and treble. Stereo sources can be directly connected to the Q450 or in remote rooms up to 500 feet away, using the optional individual fully balanced remote plates and a single Cat5e or Cat6 wire. These remote source plates can be ordered with or without Bluetooth and the Q450 can be ordered with Knoll keypads (and Knoll remote controls) or RS232 control. It’s all housed in a wall-mount enclosure. There are two versions: a 25-watt and 50-watt.
