Choosing the Appropriate Tap

70-volt systems are the number one choice for any application where you want to install multiple speakers. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up the speakers with an amplifier. You always want your 70-volt amp to have at least 15 or 20% more power than the combined watts your speakers are tapped at. For example, if you have a 180-watt /70-volt amplifier, you can install fifteen 70-volt speakers that are tapped at 10 watts each or thirty 70-volt speakers that are tapped at 5 watts each as long as they total close to 150 watts. When we say the word tap, what we are referring to is the selector knob on the control panel of the DCS6T speakers. It allows you to set how many watts the built-in transformer will allow the speaker to get from the amplifier. The taps set at 1.5, 2.5, 5 and 10 watts for 70-volt input and 2.5, 5 and 10 watts for 100-volt input. This range of taps allows for full customization of the sound for the space in which the speakers are installed. In a restaurant, for example, you can tap your dining room speakers at 5 watts, the speakers in the outside seating area at 10 watts, the ones in the hallway at 2.5 watts and the speakers in the bathrooms at 5 watts. Another great feature of 70-volt speakers is that you can mix and match any type whether they are ceiling speakers (such as these), wall mounted speakers, subwoofers, etc. 

Another benefit of 70-volt speaker set-ups is the ability to run very long lines of speaker wire without signal loss. And, the wiring is very simple. You just connect all the positive terminals of the speakers to the positive 70-volt terminal(s) of the amplifier. The negative terminals on the speaker get connected to the negative (COM) terminal(s) of the amp. You do not have to worry about impedance as the power is constant.

Setup

70V/100V Speaker Configuration.

The total number of speakers multiplied by the tap value cannot exceed the output power (in watts) of your 70V/100V amplifier. The example on the facing page shows 4 total speakers. Using the 10W taps, you will need an amplifier with at least 40 watts (4 x 10 = 40W). A good rule of thumb is to select an amplifier with 15 to 20% greater power; in this case, an amplifier that delivers about 50W.

4 Speakers Connected in Parallel Using 10W Taps

8-Ohm Speaker Configuration

Installation

Tools needed: Drywall knife, wire strippers, tape measure, ladder

2ft x 2ft Drop Ceiling Tile

1. Remove the existing tile. Measure it, then cut it in half.

2. Insert a support rail (not included) in the center of the space.

3. Carefully drop the DCS6T speaker on one side of the opening. Make sure that it is properly seated on the
ceiling grid.

4. Place the cut half of the 2ft x 2ft ceiling tile on the other side of the opening. Make sure that it is properly seated on the ceiling grid. We recommend using a safety strap to secure the speaker to the ceiling via the safety hook.

Wiring

Use a small flathead screwdriver to loosen the terminal screw (fig. a). Strip 0.25˝ of sheathing from the speaker wire. Insert the wire into the terminal (fig. b) and tighten the screw (fig. c). Please note, the Euroblock terminal can be removed so you can preconnect the speaker wires prior to installing the speaker.
