PRODUCT DESCRIPTIO N The Concourse Q6A and AM3 are Active two-way high performance speaker systems designed for sound reinforcement, audio-visual and music delivery applications. They combine quality transducers with high efficiency dedicated power amplifiers to deliver the highest possible performance in lightweight and durable ABS enclosures. Each model comes complete with mounting brackets and hardware, facilitating easy installation. correct voltage is selected before powering up this unit. Please check with your QUAD Industrial sales office or local distributor to ensure you have the correct version. P R O D U C T F E AT U R E S ( Q 8 A s h o w n ) The Q6A and AM3 are fitted with a removable metal grille finished with an opaque cloth backing. Two LEDs in the lower right front of the cabinet indicate power status (Green) and Amplifier Clip (Yellow). Concourse Q6A The Concourse Q6A is an active, two-way speaker system consisting of a 6. 5" low-frequency driver and a 1" dome tweeter combined with a 50 watt, high-efficiency power amplifier. Be aware of the position of the voltage selection switch before connecting the power cord and be sure that the correct voltage is selected before powering up the unit. Each unit is supplied with a wall mounting bracket. There are two versions available: · Concourse Q6AW ­ White color · Concourse Q6AG ­ Gray color Soft Dome HF Driver Concourse AM3 The Concourse Q6A is an active two-way speaker system consisting of an 8" low frequency driver and a 1" dome tweeter combined with a 50 watt high-efficiency power amplifier. Each unit is supplied with a wall mounting bracket. There are two versions available: · Concourse AM3W ­ White color · Concourse AM3G ­ Gray color NOTE: Power cords supplied with Q6A and AM3 models vary by country of sale. Be aware of the position of the voltage selection switch before connecting the power cord and be sure that the LF Cone Driver Bass Port Yellow Clip LED Green Power LED Q6A and AM3 models include a switchable voltage power supply that accepts either 110-120VAC or 220-240VAC line power. Unbalanced connections are acceptable only where the mixer does not offer balanced outputs and where the cable runs are less than 5m/15'. Determine where the speakers will be placed and ensure that there is AC power available nearby. In instances where there is no local power outlet you may need to provide an extension cable. Ensure that all local and national electrical codes are observed and that the power cable used is properly rated. If in doubt consult with a certified electrician or electrical engineer. However this configuration will present the signal source with a lower impedance than it would typically drive and may cause added distortion or even damage to the source outputs. The recommended method for connection of multiple Q6A and AM3 active loudspeakers to one source output is through use of a suitable active distribution amplifier or passive splitter. UNBALANCED CONNECTIONS For unbalanced operation connect the mixer or preamplifier directly to the RCA input by means of a standard unbalanced RCA cable. Unbalanced connections employ one conductor to pass the audio signal and a second conductor to act as both audio common and shield. Unbalanced connections are susceptible to radio frequency interference and electromagnetic interference which may cause the speaker to hum, buzz or even rebroadcast audio signals. For this reason, observe the following guidelines when making unbalanced connections: · Don't use cables longer than 5m (15') · Avoid running cables near electric motors, appliances, television sets or other sources of electromagnetic interference · Ensure that the speakers and mixer, or preamplifier, are all connected to the same AC power circuit to prevent possible ground loops BALANCED CONNEC T I O N S Balanced connections require a quality, two-conductor shielded cable. Balanced connections require one conductor for the positive (+) signal and one conductor for the negative (-) signal, a third conductor (shield) to create a direct connection to ground (Earth). Remove the detachable connector plug supplied with the speaker. [. . . ] Balanced lines may be extended in parallel between speakers, allowing several speakers to be driven from one mixer output. O P E R AT I O N Ensure that the power switch is in the OFF position before connecting the power cable to the AC Input socket. Connect the cable to a nearby AC Mains outlet and the then plug in the audio input cable. Rotate the volume control counter-clockwise to the minimum setting before switching the power on. Start the program source and set the preamplifier or mixer gain to a nominal level. 8 Then, slowly increase the speaker's level by turning the Volume control counter-clockwise until the sound level is adequate for the application. TROUBLESHOOTING NOTE: The Concourse Q6A and AM3 are not user-serviceable, and no attempt should be made to repair or modify the electronics in the field. [. . . ]
