Note: All wiring must comply with NFPA 70.

Nyquist PoE Amplifier and Speaker Configuration

Necessary Components: NQ-GA10P or NQ-GA10PV

Refer to Figure 1 for electrical connections.
Mount the VoIP Intercom Module (NQ-GA10P) onto the speaker’s
mounting plate (refer to Figure 2).
Refer to Figure 3 for the placement of mounting holes for
specific modules.

Wiring Instructions

Run at least a Cat 5 cable from the appropriate-sized PoE switch
to the VoIP module.

Wire the output of the VoIP module to the CSD speaker in the 8
configuration (refer to Figure 4).

Nyquist PoE Amplifier and 25V/70V Speaker Configuration

Necessary Components: NQ-GA10P, NQ-GA10PV, NQ-GA20P2, NQ-GA40P3,
and NQ-GAXMR1

Refer to Figure 5 for the mounting of the VoIP Intercom Module
(NQ-GA10P) and Distributed Audio Transformer (NQ-GAXMR1) onto the
speaker’s mounting plate.
Refer to Figure 3 for the placement of mounting holes for these
two modules.

Wiring Instructions

Run at least a Cat 5 cable from the appropriate-sized PoE switch
and connect it to the PoE amplifier module.

Refer to Figure 6 for the connection between NQ-GA40P3 and
NQ-GAXMR1. The NQ-GA40P3 can be replaced by NQ-GA10P/V or NQ-GA20P2
(refer to Figures 7 and 8). Connect the NQ-GAXMR1 to the CSD2X2U-V2
speaker using 25V wiring. If additional speakers are needed, ensure
proper wiring to prevent amplifier overload.

The CSD2X2U-V2 ceiling speaker has an 8 driver and a tap selector that allows it to be run as a ¼W to 4W speaker at 25V or 70V. It also includes a wire that bypasses the transformer and allows the speaker to operate at 8. The V2 version of the speaker includes a unique mounting plate to greatly expand its capabilities by allowing several of Bogen’s Nyquist products to be mounted to the speaker.

Mounting Plate
The mounting plate allows for the addition of several of Bogen’s Nyquist products, including the NQ-GA10P, NQGA10PV, NQ-GA20P2, NQ-GA40P3, and the NQ-GAXMR1. Through this product integration, the CSD2X2U-V2 can operate as a Nyquist PoE-enabled active loudspeaker system as well as a VoIP intercom station.

Passive Speaker Configuration

Electrical Connection

1. Remove cover, install cable clamp (if desired), and feed intercon-

necting cable into the electrical box (see Figure 1).

2. See table on the right to select speaker leads for desired system type.

3. Cut bare wire tip off of unused speaker leads. Secure all mechanical connections and reinstall the cover.

4. Set tapselector

Wiring Instructions
Run, at minimum, a Cat 5 cable from the appropriate-sized PoE switch to the VoIP module. Wire the output of the VoIP module to the CSD speaker in the 8 configuration (see Figure 4). This has a 10W maximum at 8 operation.

Wiring Instructions
Run, at minimum, a Cat 5 cable from the appropriate-sized PoE switch and connect this to the PoE amplifier module.
Figure 6 shows the NQ-GA40P3 connected to the NQ-GAXMR1. The NQ-GA40P3 can be replaced by either the NQGA10P/V (see Figure 7) or NQ-GA20P2 (see Figure 8) modules. These illustrations also show 25V wiring running from NQ-GAXMR1 to a CSD2X2U-V2 speaker and additional speakers if needed. 70V is also an option, but both outputs cannot be used simultaneously. If additional speakers are needed, proper care should be taken when wiring so the amplifier does not become overloaded.
