Concourse C8 version3 19/3/04 10:17 am Page 1 CONCOURSE C8 ARCHITECTURAL SERIES DIFFUSE (DUAL) TWO WAY ENCLOSURE KEY FEATURES: ✓ Two way ported round ceiling loudspeaker with 8” LF, 1” soft dome tweeter and passive crossover ✓ 150watts program, 300watts peak ✓ Selectable 4ohm or 16ohm low impedance setting. Switch accessible from below. ✓ Integral 60/30/15/7.5 watt tap line transformer ✓ Integral four point mounts swivel out from the loudspeaker to allow simple installation from below the ceiling. ✓ Back box, ‘C’ clamp included ✓ Optional mud ring and mounting plate with integral electrical back box and conduit knockouts APPLICATIONS: ✓ ✓ ✓ ✓ ✓ ✓ ✓ Corporate Meeting Rooms Classrooms Training Rooms Restaurants Retail Outlets Hotels Health Clubs DESCRIPTION: The QUAD Industrial CONCOURSE C8 is a two way round ceiling speaker with a SPECIFICATIONS: SYSTEM: Power handling: 75watts continuous, 150watts program, 300watts peak RECOMMENDED AMPLIFIER: 10-200WATTS Impedance: Selectable 4 or 16 ohms nominal Frequency response (-10dB): 45Hz-20kHz Frequency response (+/-3dB): 55Hz-20kHz Sensitivity: 88dB/1watt/1meter Max SPL: 113dB Coverage: 110*90 DIRECTIVITY (Q): 5.8 Transformer: 60-30-15-7.5 watt taps @ 70volt and 60-3015watts @ 100volt. TRANSDUCERS: LF Driver: 8” Cone HF Driver: 1” Dome tweeter Crossover Frequency: 2.3kHz 8” LF, 1” soft dome tweeter and passive crossover. The Concourse C6 is intended formedium to large room applications requiring high quality speech PHYSICAL: reinforcement and/or background music. Type: Two way passive ported design Material: ABS baffle, Powder coated aluminium grill, steel backcan Connector: Terminal strip Dimensions (WxD): 333mm (dia) x445mm Nett Weight: 5.3kg The CONCOURSE C8 has switch settings for 4 and 16 ohm low impedance, allowing efficient use of amplifier power and parallel looping connections with no transformer losses or signal degradation. For distributed applications, the CONCOURSE C8 has an integral transformer rated at 60-30-15-7.5 watt taps @ 70volts and 60-30-15 watt taps @100volts. The CONCOURSE C8 includes a back box and ‘C’ ring for weight distribution on ceiling finishes. In addition, the C8 has an optional mud ring and ceiling tile mounting (with integral terminal box containing conduit knockouts). All components (including grill) are attached to a steel tether, which in turn is attached to an external anchor point 19/3/04 10:17 am Page 2 STANDARD ACCESSORIES: ARCHITECTURAL & ENGINEERING SPECIFICATIONS: Color: White with color matched grill cloth ‘C’ Clamp: A ‘C’ clamp is included with the loudspeaker to facilitate mounting on ceiling finishes. Tile bridge: Two 2ft/600mm rails are included with the loudspeaker for mounting on ceiling grids. Back box: Included with loudspeaker Mounting: Four swivel mounts which rotate away from the loudspeaker and clamp to the ceiling finish Transformer: 70/100 volt transformer included. The loudspeaker shall consist of a two way system with a 8” low frequency driver, 1” dome tweeter and internal crossover installed in a ported plastic grill with a rear back box and ‘C’ clamp and terminal strip connection. The loudspeaker shall have selectable 4 and 16 ohm impedance, as well as an integral transformer rated at 60-30-157.5 watt taps @ 70volts and 60-30-15 watt taps @100volts. The loudspeaker shall have a color matched grill cloth to hide the transducers and switches. The loudspeaker shall have the following performance specifications: Power, 75watts continuous Sensitivity, 88 dB (1 watt, 1 meter, Hz-kHz). Usable frequency response from 45Hz to 20kHz (-10 dB); Coverage pattern of (nominal) 110*90 OPTIONAL ACCESSORIES: Mud ring: For gypsum ceiling installations prior to the loudspeaker. Ceiling Plate: For secure installations prior to the ceiling finish. Also includes a termination box with conduit knockouts Õ333 30.00 352.23 361.36 30 623.00 FRONT VIEW 85.00 Õ333 Õ293 Õ 298 445.00 Õ 338 SIDE VIEW C Ring Mounting Õ 333.00 Õ293.00 81.00 13.00 30.00 15.00 38.00 114.00 CONCOURSE C8 Concourse C8 version3 13.50 Õ 259.00 SECTION A-A SCALE 1.000 REAR VIEW Product Dimensions 90 Concourse C8 version3 19/3/04 10:17 am Page 3 100 80 90 60 80 40 70 20 0 100 1000 10000 Directivity Index,Q 20 20000 100 10 10 0 10000 0 100 Directivity Factor (Q) 60 10 Directivity Index (DI), dB Impedance(ohms) 100 CONCOURSE C8 SPL,1W/1M(dB) Frequency Response and Input Impedance 110 1000 Horizontal Off Axis Frequency Response 100.0 ATTENUATION (dB) dBSPL 90.0 0deg 10deg 80.0 20deg 30deg 70.0 40deg 60.0 20 100 1k Frequency(Hz) 10k 20k Vertical Off Axis Frequency Response(down) 100.0 ATTENUATION (dB) dBSPL 90.0 0deg 10deg 80.0 20deg 30deg 70.0 40deg 60.0 20 100 1k Frequency(Hz) 10k 20k Vertical Off Axis Frequency Response(up) 100.0 ATTENUATION (dB) dBSPL 90.0 0deg 10deg 80.0 20deg 70.0 40deg 30deg 60.0 20 100 1k Frequency(Hz) 10k 20k Concourse C8 version3 19/3/04 10:17 am Page 4 CONCOURSE C8 500Hz 1000Hz 0 330 0 330 30 -10 30 -10 -20 -20 300 300 60 -30 60 -30 -40 -40 -50 -50 270 90 Clio 270 Clio 90 120 240 120 240 210 210 150 150 180 180 2000Hz 4000Hz 0 330 0 330 30 30 -10 -10 -20 -20 300 300 60 60 -30 -30 -40 -40 -50 -50 90 Clio 270 120 240 210 90 Clio Clio 270 120 240 150 210 150 180 180 8000Hz 0 330 30 -10 -20 300 60 -30 -40 -50 Clio 270 90 120 240 210 150 180 IAG House, Sovereign Court, Ermine Business Park, Huntingdon.
