PRODUCT DESCRIPTIO N The Concourse C series are two-way, high performance ceiling mounted speaker systems designed for distributed music, paging and speech applications. Packaged in pairs (except the C-SUB and C-SUBT) and including all needed mounting accessories, the C series models are complete vented speaker assemblies with a metal back box, ABS front baffle and attractive metal grille. Each model is available in both low-impedance 16 and constant-voltage 70/100V versions (with T suffix). Concourse C8 The Concourse C8 is a two-way ceiling mounted speaker system consisting of an 8" dual voice coil cone low frequency driver and a 1" soft dome tweeter. Speakers are packed in pairs and come complete with a tile backing C-ring, mounting support rails, plastic paint covers and cardboard cutout templates. · Concourse C8 ­ Selectable 4/16/70V/100V operation, 60W transformer included CONCOURSE 21L/21L-1 6 / C 4 T The Concourse 21L is a two-way ceiling mounted speaker system consisting of a 4" cone low frequency driver and a 1" soft dome tweeter. Speakers are packed in pairs and come complete with a tile backing C-ring, mounting support rails plastic paint covers and cardboard cutout templates. There are three versions available: · Concourse 21L ­ Selectable 4/16/70V/100V operation, 30W transformer included · Concourse 21L-16 ­ 16 version, 25 Watts · Concourse 21LT ­ 70/100 Volt operation only, 30W transformer included Concourse CSUB The Concourse CSUB is a ceiling mounted subwoofer system consisting of a 10" sub bass driver and integral low-pass crossover. The CSUB is fitted with dual low-impedance voice coils allowing connection to stereo power amplifiers at either 4 or 16, or to 70/100V amplifiers through a built-in 100W transformer. · Concourse CSUB ­ Selectable 4/16/70V/100V operation, dual 50W low impedance coils, 100W transformer included Concourse C6 The Concourse C6 is a two-way ceiling mounted speaker system consisting of a 6" cone low frequency driver and a 1" soft dome tweeter. Center the C ring around the opening. C-RING Step Remove the screws holding the terminal cover plate and then remove any knock outs needed to connect the speaker wiring. STEP 4 Step Select the appropriate impedance using the push-button switch inside the terminal box if the speaker is part of a low impedance system (except 21LT and 21L-16). Step 6 Lift the speaker to the ceiling and terminate the wiring to the terminal strip. Replace the cover plate and screws. 9 Step Lift the speaker into the opening, then using a screwdriver tighten each of the four mounting screws in sequence. Turning the screws in a clockwise direction will cause the mounting clamps to rotate into position then extend down to clamp the assembly to the ceiling. STEP 7 Step 8 Set the correct wattage tap (except 21L-16) using the front mounted rotary power switch. NOTE: The switch is labeled for both 70V and 100V power taps; ensure you select the correct tap for the connected amplifier. Step 9 If the speaker bezel is to be painted, place the supplied clear plastic paint cover over the front. Otherwise, attach the grille restraint tether by inserting the plastic plug into the hole on the inside of the bezel and then seat the grille to the bezel by pushing firmly around the perimeter of the grille. 10 WIRI NG & CONNECT I O N S Ensure that all wiring is installed in compliance with local laws, codes and convention. Obtain all necessary permits and approvals and use only cable that is approved for the application and is sized to safely accommodate the load. Models C / CT / C6 / C8 and CSUB These models include two internal crossover networks allowing either 4 or 16 low impedance operation. In addition they include 70/100V transformers for use in distributed systems. For 70/100V operation select the appropriate wattage tap using the rotary selector switch. Note that one side of the switch is labeled for 70V operation and the other side for 100V systems. Ensure that the power is set for the correct amplifier connected. [. . . ] Ensure that the power is set for the correct amplifier connected. NOTE: DO NOT USE THE "0" SETTING WHEN CONNECTED TO A 100V SOURCE!Select the power tap by dividing the amplifier's available power by the number of speakers to be connected and then selecting the next lower wattage tap. For example: 300W amplifier ÷ 20 speakers = 15 Watts; use the 15W terminal Individual speakers may be tapped higher or lower in order to better balance the system sound pressure level in different areas.
