Installation Checklist
Plan your installation. Consider what
sources will be used and make provisions for infrared and sources, speakers and cabling.
Collect the proper tools. Run all wires and label both ends. Install speakers as directed by speaker
manufacturer. Test wire for short circuits.
Terminate cat5 and test for short circuits
and polarity for MR44 and BIX/BIB modules. Retest.
Mount Q450 if necessary. Test speaker wire for shorts and correct
impedance with ohm meter.
Connect speakers. Note which zone is for
which room and which source is from which location.
Connect cat5 connectors. Ensure cat5
keypads and sources are going to the correct socket.
Connect audio outputs to Q450 or to ‘local’
BIX/BIB inputs. Make a note of which input is used for each source.
Test all installed cabling before connecting to the Q450. Test the speaker and wires with a multi-meter set to ohms for correct impedance and short circuits. Resistance and impedance differ slightly so a very accurate reading is not expected. Long speaker wires will increase resistance. This also includes cat5 connectors. Incorrect polarity of a twisted pair can cause serious damage to the Q450 and its peripherals.
Do not make any wire connections of any kind with the power supply connected.
During operation, the amplifier may become warm. This is normal; there are instances during high­level playback into low impedance speakers when the amplifier will become much warmer than usual. To ensure the amplifiers trouble-free operation, it is necessary to provide adequate ventilation. Keep the amplifier away from external sources of heat such as radiators and hot-air ducts. Never place the amplifier with other heat-producing components in a cabinet or enclosure lacking free airflow. Do not stack other components on top of your Q450.
Care, maintenance, and cleaning: wipe with clean, dry, soft cloth. If necessary, first wipe the surface with a slightly dampened soft cloth with mild soapy water, then with a fresh cloth dampened with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene, thinner, alcohol, or any other volatile cleaning agent. Do not use abrasive cleaners, as they will damage the finish of the metal parts. Avoid spraying insecticides, waxes, polishing agents, or any aerosol product near the Q450 or any of its components.
It is best to run extra cat5 wires to each room as this will make the installation more future proof and offers an inexpensive repair if a cable is damaged.
It is important to know where the various wires required to operate the Q450 will be run. Never run a cat5 or speaker cable parallel to a high voltage AC mains cable. This may cause problems with the operation of Q450. If possible do not locate a keypad next to a light switch for the same reason.
The Q450 needs to be a safe distance from any large AC motors, including an air conditioner, or fridge/freezer, or breaker panels as tis can cause unwanted interference.

WHAT IS IT?
MR44 Keypad and BIX Remote Input
WHO IS IT FOR?
The Q450 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.
The balanced inputs eXtenders (BIB and BIX) have a feature we are very proud of and we hope you will too. These plates allow the Q450 to have an input from a room or space far away from the Q450 without any drop in signal quality and best of all without any added unwanted hum and noise. This is an industry first.
Lets put this another way. Say you are enjoying a dip in the
tub. Wouldn’t it be nice to be able to plug in your iPod
beside the tub and not have to run to the amp to change a playlist? Best of all, the floor stays dry!
Cat5 is very reliable wire. The MR44 keypad and our
balanced input modules both use cat5. We use cat5 connectors terminated to the T568A protocol. It is highly recommended to adhere to this standard.
Speaker Connectors. We use a detachable connector sometimes called a phoenix connector. There are four connectors included in the Q450 pack. Each connects one stereo zone.
Balanced Input eXtenders (BIB and BIX). Extender plates allow stereo sources (iPod, CD player, etc.) to
be in rooms close or far (up to 1000’ or 300m) to the
Q450. The BIX has a 3.5mm stereo input jack and an emitter output. The BIB is nearly identical with an
added HD Bluetooth receiver.
The MR44 keypad is your control center, providing access to the four different sources, volume, bass, treble, mute, all off and an infrared (IR) pass through that you can use to control attached devices.
