Atlas Sound TSD-PA10VG – 10W Mono Distributed Audio Amplifier 4Ω/70V/100V

Product Overview

The Atlas Sound TSD-PA10VG is a compact 10W mono power amplifier supporting 4Ω, 25V, 70.7V, and 100V speaker loads for small-zone distributed audio applications. This mini commercial amplifier is designed for house of worship cry rooms, restrooms, foyers, retail fill zones, and small conference rooms where a full-size amplifier would be excessive. With a balanced input, removable Phoenix-style connectors, and a tamper-resistant level control, the TSD-PA10VG installs behind walls or inside cabinetry with minimal visible footprint.

Product Description

The TSD-PA10VG fills a specific gap in distributed audio systems: zones that require independent amplification but cannot justify a full rack-mount amplifier. A single unit drives up to eight 25V/70V/100V ceiling speakers tapped at 1W each, or up to 17 sound masking speakers tapped at 0.5W each on a 70.7V line—making it viable for both background music and speech privacy applications. The balanced input accepts 500mV (-6dBV) line-level signals from DSPs, audio processors, or mixer outputs. Input signal and peak indicator LEDs on the front panel provide at-a-glance status without requiring a separate monitoring tool. The front-panel level potentiometer includes a removable knob, and a tamper-resistant security cover is included—once set, the level can be locked to prevent unauthorized adjustment. Removable Phoenix-style I/O connectors simplify wiring and allow the amplifier chassis to be swapped without re-terminating field wiring. An integrated cable management system keeps wiring organized within the compact enclosure. The TSD-PA10VG runs on 24VDC at 500mA, sold separately, which allows flexible mounting independent of AC outlet placement. THD measures 0.5% at 1 kHz, acceptable for background music and paging applications. The chassis measures 4" wide x 1.5" tall x 2.75" deep, small enough to mount inside junction boxes or equipment closets.

Key Features

• 10W Output at 4Ω / 25V / 70.7V / 100V — Compatible with both low-impedance and constant-voltage distributed speaker systems.
• Balanced Line Input — 500mV (-6dBV) balanced input rejects common-mode noise on long cable runs.
• Tamper-Resistant Level Control — Removable knob with security cover locks the output level after commissioning.
• Removable Phoenix-Style I/O Connectors — Field wiring stays in place when the amplifier chassis is serviced or replaced.
• Input Signal and Peak LEDs — Front-panel indicators confirm signal presence and alert to clipping.
• Integrated Cable Management — Built-in system organizes wiring within the compact chassis.
• 24VDC Power (External Supply) — DC power input enables flexible remote mounting away from AC outlets.
• Ultra-Compact Chassis — 4" x 1.5" x 2.75" footprint fits concealed mounting locations.
• Low THD (0.5% @ 1kHz) — Clean audio reproduction suitable for music and paging applications.
