The Grommes~Precision AX60G is a 60-watt commercial power amplifier designed for background music, telephone paging, and distributed sound systems. Part of the AXIOM-G Series, this American-made amplifier combines continuous RMS output power, flexible speaker connections, and automatic paging priority in a compact 2U rack-mount design.
With support for 4–8 ohm speakers and transformer-isolated 25V and 70.7V speaker lines, the AX60G provides a practical amplification solution for retail stores, offices, restaurants, classrooms, and smaller commercial facilities. Its straightforward controls and integrated paging features make it especially useful where background music and voice announcements share the same speaker system.
60 Watts of Continuous RMS Power
The AX60G delivers 60 watts of continuous RMS power for commercial audio installations that do not require a higher-powered amplifier.
Its heavy-duty power supply is engineered for consistent operation, providing dependable amplification for background music and paging throughout the business day.
For smaller 70V systems, the AX60G offers an efficient alternative to using an unnecessarily large amplifier. Installers should calculate the total speaker transformer tap load and allow appropriate system headroom when selecting amplifier capacity.
Flexible 4–8 Ohm, 25V, and 70.7V Speaker Outputs
The AX60G accommodates conventional low-impedance speakers as well as distributed speaker systems using 25V or 70.7V lines.
A built-in isolation transformer supports commercial ceiling speakers, wall-mounted speakers, and paging horns equipped with compatible transformers.
This flexibility makes the amplifier suitable for both localized sound systems and installations with multiple speakers connected along a distributed audio line.
Telephone Paging with Automatic Music Muting
The AX60G includes an independent balanced 600-ohm telephone paging input with its own gain adjustment.
When a paging announcement is detected, the amplifier can automatically reduce the auxiliary audio signal, allowing announcements to take priority over background music.
The voice-activated muting function is defeatable, giving installers flexibility when configuring the system for different applications.
Auxiliary Inputs for Background Music
Two parallel auxiliary inputs allow connection of a compatible line-level music source.
The AX60G uses a 1.5-channel mixing configuration consisting of the main auxiliary audio path and an independent telephone paging input.
This arrangement simplifies commercial sound installations that need both background music and paging without the complexity of a multichannel mixing amplifier.
Built-In Protection for Reliable Operation
The AX60G incorporates multiple protection circuits to help safeguard the amplifier and connected equipment.
Protection features include short-circuit protection, peak overload protection, current limiting, thermal protection, an AC circuit breaker, and an output relay designed to minimize unwanted speaker noise during startup.
The heavy-duty power supply and convection-cooled construction support dependable continuous operation.
The AX60G is backed by Grommes~Precision's 7-year manufacturer's warranty, providing additional confidence for long-term commercial audio installations.
Compact 2U Rack-Mount Design
The AX60G features a standard 19-inch rack-mount chassis occupying just two rack spaces.
Its convection-cooled design eliminates the need for an internal cooling fan, reducing fan noise and routine maintenance. Proper ventilation must still be provided according to the manufacturer's installation instructions.
Weighing approximately 12 pounds, the AX60G is lighter than the higher-powered AXIOM-G models while retaining the same commercial-grade construction.
Designed and manufactured in the USA, the AX60G reflects Grommes~Precision's long history of producing professional audio equipment for commercial and industrial applications.
