AtlasIED TSD-PA10VG 10W Mono Power Amplifier – 4Ω, 25V, 70V and 100V

The AtlasIED TSD-PA10VG is a compact, energy-efficient 10-watt mono power amplifier designed for small commercial audio zones requiring either low-impedance or constant-voltage speaker operation. Supporting 4Ω, 25V, 70.7V, and 100V speaker systems, this versatile amplifier provides a practical solution for background music, paging, sound masking, and localized sound reinforcement applications.

Ideal for houses of worship, classrooms, restrooms, foyers, offices, and small commercial spaces, the TSD-PA10VG delivers up to 10 watts into a 4Ω load or compatible 25V, 70.7V, and 100V distributed speaker systems. It also supports 8Ω speakers at a reduced output of 5 watts.

For distributed audio installations, the amplifier can power up to eight ceiling speakers tapped at 1 watt each, making it a convenient choice for small paging or background music zones. In sound masking systems, it can support up to 17 compatible masking loudspeakers tapped at 0.5 watts each on a 70.7V line, provided the total connected load remains within the amplifier's rated capacity.

The TSD-PA10VG features a balanced line-level input, front-panel gain adjustment, signal and peak indicators, removable Phoenix-style connectors, and a tamper-resistant security cover. Its compact AtlasIED Time Saving Devices (TSD) Series enclosure allows installation where a conventional rack-mount amplifier would be unnecessarily large.

Features and Benefits

Flexible Low-Impedance and Constant-Voltage Operation

The TSD-PA10VG supports multiple speaker system configurations, including 4Ω, 25V, 70.7V, and 100V operation.

This flexibility makes it suitable for both individual low-impedance loudspeakers and distributed commercial speaker systems using transformer taps.

The amplifier delivers 10 watts at 4Ω or compatible constant-voltage loads and 5 watts at 8Ω.

10-Watt Output for Small Audio Zones

With up to 10 watts of output power, the TSD-PA10VG is well suited for localized audio applications where a larger commercial amplifier is unnecessary.

It can support small paging zones, background music systems, projector audio, and auxiliary speaker areas in commercial buildings.

Supports Multiple Distributed Ceiling Speakers

For 25V, 70.7V, or 100V speaker installations, the TSD-PA10VG can power up to eight compatible ceiling speakers tapped at 1 watt each.

This provides an efficient solution for hallways, restrooms, small offices, and other areas requiring low-level distributed audio.

The combined speaker tap wattage must remain within the amplifier's rated output.

Suitable for Small Sound Masking Systems

The amplifier can drive up to 17 compatible masking speakers tapped at 0.5 watts each on a 70.7V speaker line.

This makes it useful for localized sound masking applications in offices, professional facilities, and other commercial environments where consistent background sound is needed.

A separate sound masking generator or other suitable audio source is required.

Balanced Line-Level Audio Input

The TSD-PA10VG includes one balanced line-level input with a nominal input sensitivity of 500mV (-6dBV).

The balanced connection allows integration with compatible mixers, audio processors, paging equipment, and sound masking generators while helping minimize interference in properly installed systems.

Front-Panel Level Control with Security Cover

A convenient front-panel level control allows installers to adjust amplifier output during system setup.

Once the correct level has been established, the removable knob can be replaced with the included security cover to help prevent accidental or unauthorized changes.

Signal, Peak, and Power Indicators

Front-panel LEDs provide visual feedback during installation and operation.

The green signal indicator confirms input activity, the red peak indicator helps identify excessive signal levels, and the blue power indicator confirms operation.

Compact Installation and Cable Management

The compact TSD Series aluminum chassis measures only 1.5 inches high, 4 inches wide, and 2.75 inches deep.

Removable Phoenix-style connectors, included mounting hardware, and cable management accessories help simplify installation in equipment cabinets, behind displays, or in other space-constrained locations.

Energy-Efficient Operation

The TSD-PA10VG is designed for efficient operation in commercial audio systems, with low idle power consumption.

Its small footprint and efficient design make it a practical alternative to larger amplifiers for low-power speaker zones.

External 24V DC Power Supply

The amplifier requires a compatible external 24V DC power supply, sold separately.

AtlasIED specifies a 500mA power supply capacity for the TSD-PA10VG in its product information and power supply calculator.

Compatible AtlasIED power supply options include the TSD-PS24V500MA and higher-capacity TSD 24V power supplies, subject to the total system requirements.
