WHAT IS IT? WHO IS IT FOR? The Q450rs is a four source, four-zone multi-room controller amplifier in a small, efficient package. It is much like having four integrated hifi amplifiers hidden away from sight and connected together for a seamless listening experience. It is equally comfortable at home as it is scaled up, using the controlled audio outputs, for larger installations such as art galleries or coffee shops. BIX Remote Input Wall Plate The Q450rs is controlled by RS232 commands.
Line Inputs Controlled Outputs Direct, non-balanced RCA inputs. We do not suggest connecting a line input and a balanced input(BIB) on the same input. It is acceptable to have (for example) a direct input on 1 and 2 and balanced inputs on 3 and 4. The line level controlled outputs the same content as the amplified outputs but at lower level that can feed larger and/or multiple amplifiers.
This configuration shows a laptop connected to the RS232 port to control the Q450rs. A BIX balanced input wall plate is shown connected to input #1. The speakers are shown connected to the Q450rs amp #1 outputs. Before trim out (or final installation) always doublecheck the wires for continuity and short circuits as problems can arise such as a tradesperson driving a screw through the wire.
RS232 Connection The RS232 connection is used to control the Q450RS by an external controller or computer and can work with our without keypads. The Q450RS connects to the RS232 controller with a 9-pin db9 connector. The programming reference follows.
Note: Some commands are read or write only and some are both. For example “Mute All” is a write only command and “Version” is a read only command.

Correct polarity connections are important to maintain proper speaker phasing. When speaker phasing is correct, all speakers move in and out at the same time preserving the imaging and bass response of the program material.
EXPANDING CAPABILITIES exact same way as the Q450rs integrated amplifiers do. The Q450rs sports some unique features that This will allow for fine tuning the output volume of your sub zone so there aren’t spots that are too loud or too quiet. provide for larger and more sophisticated installations. To control any amplifier a larger zone will require additional equipment.
INSTALLATION INSTALLATION PROCEDURE Tools You Will Need Installing the Q450rs is intended to be a relatively easy procedure with no programming required. These tools are specific to Q450rs and more may be required depending on speakers and peripherals used. Part One - Planning A small flat head screw driver with a blade that is about 3.5mm (1/4”) is ideal. This is for terminating the speakers into the Q450rs speaker or Phoenix connector.
TROUBLESHOOTING No Q450rs Power 1. 2. 3. Observe LED on Q450rs is on. Check to see if Q450rs is plugged in. Test AC outlet with a lamp to see if it is active. Q450rs led on but no sound 1. 2. 3. 4. Ensure the source input is connected to the input selected and the source is playing. If a BIX or BIB balanced input plate is being used, inspect and if necessary test the cat5 cable with a cat5 tester.
