The Bogen CSD2X2U-V2 is a versatile ceiling speaker designed for drop ceilings (the kind with tiles). It’s suitable for a wide range of commercial and institutional audio systems. It supports multiple wiring configurations and can even function as part of an IP or paging system.

Key Features & Benefits

1. Flexible Wiring Options

• Works at 8 ohms (direct connection) or in 25 V / 70 V systems (for long cable runs in buildings).

• You choose the power level ("tap") when you wire it, depending on how loud you want it or how far away it is.

2. Easy Installation

• Just unpack the speaker, connect your wiring (8 Ω or 25 V/70 V), and select the proper tap setting.

• It drops into standard ceiling grids (drop ceilings).

3. Can Become Part of an IP / Intercom System

• You can convert it into a Nyquist passive IP speaker or IP intercom speaker by adding modules like the Nyquist GA10P (VoIP intercom module).

• This gives you flexibility for future upgrades or mixed audio + paging systems.

4. Acts as a Source Amplifier + Speaker

• It can operate not just as a speaker, but also as a 25 V / 70 V amplifier + speaker combo.

• In this mode, it can feed (daisy-chain) power to other speakers further down the line.

• Requires optional equipment (Nyquist GA-series amplifier and NQ-GAXMR1 transformer) to work in this mode.

5. Plenum Rated & Safety Compliant

• Meets UL 2043 and UL 62368 standards—safe for use in plenum spaces (the airflow zone above ceiling tiles). Bogen

• “Plenum” rating means it’s suitable for air-handling spaces, an important requirement in many commercial buildings.
