CSD2X2U-V2
70V, 25V, and 8Ω Speaker System
Installation and Use Guide

2
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 8Ω. 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, NQ-
GA10PV, 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 Conguration
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 tap selector switch to proper tap setting.
Note: All wiring must comply with NFPA 70.

Necessary components: NQ-GA10P or NQ-GA10PV.
Figure 2 shows the positioning for the mounting of the VoIP Intercom Module (NQ-GA10P) onto the speaker’s mount-
ing plate. For a closer look at the mounting plate, refer to Figure 3.

CSDV2 Mounting Plate
The placement of mounting holes varies per module
(see Figure 3). They are as follows:
A = NQ-GAXMR1
B = NQ-GA40P3
C = NQ-GA10P, NQ-GA10PV, or NQ-GA20P2
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 8Ω conguration (see Figure 4). This has a 10W maximum at 8Ω operation.

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

Wiring Instructions
Run, at minimum, a Cat 5 cable from the appropriate-sized PoE switch and connect this to the PoE amplier module.
Figure 6 shows the NQ-GA40P3 connected to the NQ-GAXMR1. The NQ-GA40P3 can be replaced by either the NQ-
GA10P/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 out-
puts cannot be used simultaneously. If additional speakers are needed, proper care should be taken when wiring so
the amplier does not become overloaded.
