The AtlasIED AT35-PARM is a professional 35-watt rack-mount volume control with priority paging override, designed for 25V and 70.7V commercial distributed audio systems. Combining reliable speaker volume adjustment with paging override functionality, the AT35-PARM is an excellent solution for commercial paging, background music, and installed sound applications.
Featuring a high-quality autotransformer, the AT35-PARM provides 27 dB of total attenuation through ten make-before-break volume steps and a positive off position. Its silver-plated switch contacts are designed to provide dependable operation while minimizing unwanted switching noise.
Unlike standard volume attenuators, the AT35-PARM incorporates a priority paging override relay, allowing designated paging signals to bypass the normal volume setting when the override is activated.
The unit features a matte black polycarbonate dial scale overlay with adhesive backing and a matching skirted black knob, making it suitable for installation in compatible rack panels and centralized audio control systems.
35W Volume Control for 25V and 70.7V Audio Systems
The AtlasIED AT35-PARM is designed for commercial distributed speaker systems operating at 25V or 70.7V.
Its 35-watt power rating makes it suitable for compatible speaker circuits with a combined transformer load within the control's rated capacity.
The AT35-PARM allows operators to adjust speaker volume independently without changing the main amplifier output.
This makes it useful in installations where multiple areas require different background music or paging levels.
Typical applications include:
- Commercial office buildings
- Restaurants and retail stores
- Schools and educational facilities
- Hospitality properties
- Healthcare administrative areas
- Industrial facilities
- Commercial paging systems
Priority Paging Override for Important Announcements
A distinguishing feature of the AT35-PARM is its integrated priority paging override capability.
The unit incorporates an SPDT relay operated by a 24VDC control signal at 10mA.
When activated by a compatible paging control system, the relay bypasses the attenuator's normal volume setting so designated announcements can be heard at the system's paging level.
This is especially useful in commercial audio installations where occupants may have reduced the background music volume or turned a local speaker circuit down.
Potential applications include:
- Facility-wide announcements
- Priority paging systems
- School administrative paging
- Commercial public address systems
- Industrial communication systems
Important: The paging override function does not, by itself, establish compliance with emergency voice evacuation or life-safety system requirements.
Ten Make-Before-Break Attenuation Steps
The AT35-PARM provides ten attenuation steps plus a positive off position, giving users convenient manual control over connected speaker circuits.
The make-before-break switching design maintains circuit continuity during adjustments, helping reduce switching interruptions.
With 27 dB of total attenuation, the AT35-PARM allows the volume to be reduced to suit the listening environment.
Silver-plated switch contacts support reliable operation and help minimize unwanted switching noise.
Rack Mount Design for Centralized Audio Control
The AtlasIED AT35-PARM is designed for installation in compatible equipment rack panels.
Instead of a conventional wall plate, it features a matte black polycarbonate dial scale overlay with adhesive backing.
The included skirted black knob provides a clean, professional appearance and convenient manual adjustment.
This configuration makes the AT35-PARM particularly useful in centralized equipment racks where multiple speaker circuits require independent volume control.
Its compact dimensions allow installers to organize volume controls without requiring a separate wall-mounted enclosure for each circuit.
Removable Terminal Block for Easier Installation
The AT35-PARM includes a removable terminal block to simplify wiring and service.
This design helps installers connect the speaker circuit and integrate the volume control into compatible commercial audio systems.
When installing the AT35-PARM, verify that the connected speaker load remains within the 35-watt rating and that the paging control equipment provides the appropriate relay activation signal.
