Installation Instructions for Optional Plaster Ring
An optional plaster (mud) ring bracket is available from TANNOY. This bracket is designed to be pre-installed into newly constructed, non-suspended ceilings.
1. Nail or screw the plaster ring to the joists.
2. Lay the speaker wiring to where the speaker will be fi tted and complete the plastering work on the ceiling.
3. Cut out the hole in the ceiling using a circular saw or pad saw.
4. Go to page 15 for instructions on wiring then return to point 5 below.
5. Slide the speaker assembly through the hole and turn the screws to extend the mounting wings.
Tighten the screws until a fi rm grip is achieved.
If using a power driver, TANNOY recommends a torque setting of 1.5 Nm.
DO NOT OVERTIGHTEN!
6. Connect a Secondary Support Line to safety tab. Some construction codes require use of this secondary
support point, which should connect to a separate secure support point using a suitable support line.
Consult construction codes in your region.
7. Insert grille by pushing it onto the speaker.
Wiring and Setting Up
1. Open the wiring cover at the back of the speaker can to access the Euro type connector plug and socket.
2. For connection to an amplifi er, use pins 1 and 2:
• Pin 1 is positive
• Pin 2 is negative
For connection to additional speakers in a distributed line, pins 3 and 4 are in parallel where:
• Pin 3 is negative
• Pin 4 is positive
3. Close the wiring cover and tighten both screws on the cable clamp. Use the rotary switch located
on the front of the unit to select whether you wish to use the speaker in a low-impedance or
distributed-line application.
THE SPEAKER IS SUPPLIED IN LOW IMPEDANCE MODE. NEVER CONNECT THE SPEAKER TO
A 70/100 VOLT AMPLIFIER WHILE IT IS SET FOR LOW IMPEDANCE.
4. The CVS 4 is fi tted with a 15 W transformer. When used in distributed-line systems, the transformer can
be tapped at 15 W, 7.5 W and 3.5 W, with an additional 1.9 W tapping for 70.7 V line systems.
5. The CVS 4 is fi tted with a 30 W transformer. When used in distributed-line systems, the transformer can
be tapped at 30 W, 15 W and 7.5 W, with an additional 3.75 W tapping for 70.7 V line systems.
6. The CVS 6 is fi tted with a 60 W transformer. When used in distributed-line systems, the transformer can
be tapped at 60 W, 30 W, and 15 W, with an additional 7.5 W tapping for 70.7 V line systems.
7. The CVS 8 is fi tted with a 60 W transformer. When used in distributed-line systems, the transformer can
