The AtlasIED DAT35ST70 Stereo Attenuator provides convenient wall-mounted volume control for commercial 25V and 70.7V distributed speaker systems. Designed for installations requiring two-channel audio control, this Decora-style attenuator handles up to 35 watts per channel and allows users to adjust speaker volume without changing the amplifier's main output level.

Ideal for restaurants, retail stores, offices, hospitality facilities, and commercial AV installations, the DAT35ST70 uses an autoformer design with make-before-break contacts for smooth transitions between volume settings.

The rotary control provides ten attenuation positions plus a positive off setting. At its maximum setting, the attenuator allows full-power passthrough, making it easy to return the connected speakers to their normal listening level.

Supplied with white and ivory Decora-style plates, trim rings, and matching knobs, the DAT35ST70 offers a clean appearance that blends with existing wall switches and electrical fixtures.

Stereo Volume Control for Distributed Audio Systems

The AtlasIED DAT35ST70 is designed for commercial sound installations where two channels of 25V or 70.7V audio need to be adjusted together.

Unlike a conventional mono attenuator, the DAT35ST70 provides separate left and right signal paths within a single wall-mounted control.

This makes it useful for stereo background music installations in restaurants, lounges, retail stores, and other spaces where both audio channels need convenient local volume adjustment.

The attenuator controls speaker-level signals and is installed between a compatible constant-voltage amplifier and the connected speakers.

Smooth, Stepped Volume Adjustment

The DAT35ST70 uses make-before-break switching contacts to provide smooth changes between volume settings.

Its rotary control offers ten attenuation positions and a positive off setting, allowing users to reduce speaker levels without adjusting the central amplifier.

At the maximum setting, the attenuator provides full-power passthrough.

This design is especially useful in commercial environments where employees need simple, reliable volume control throughout the day.

Decora-Style Design with Two Finish Options

The DAT35ST70 includes white and ivory wall plates, trim rings, and matching rotary knobs.

Its standard single-gang design allows installation in compatible electrical boxes with a minimum depth of 2.5 inches.

The Decora-style appearance makes the control suitable for professional spaces where visible audio controls should complement surrounding electrical fixtures.

Recommended Applications

  • Restaurants and Lounges: Local volume control for stereo background music systems.
  • Retail Stores: Convenient adjustment of music levels in sales areas.
  • Hotels and Hospitality: Wall-mounted volume control in lounges and common spaces.
  • Offices: Stereo audio level adjustment in meeting rooms and commercial areas.

Selecting the Correct Stereo Attenuator

The DAT35ST70 is rated for 35 watts per channel.

When planning an installation, calculate the total transformer tap wattage of the speakers connected to each channel. Neither channel should exceed its rated 35-watt capacity.

For example, three speakers tapped at 10 watts each would represent a 30-watt load on one channel.

Important: The DAT35ST70 is designed for 25V and 70.7V constant-voltage speaker systems. It is not intended for conventional 4-ohm or 8-ohm speaker circuits.
