Precision, Plate Mounted 250W Attenuator, 1.5dB Steps

The AtlasIED E408-250 is a precision, plate-mounted attenuator for 70.7V audio systems. Rated for 250 W, it provides 15 dB of total attenuation in 1.5 dB steps, giving users clearly defined adjustment increments from a wall-mounted control point. The assembly uses a stainless steel, 2-gang plate and carries UL813 and UL2043 safety listings.

Ideal Use Cases

This model is suited to 70.7V audio installations that require local level adjustment and a power rating of up to 250 W. Its wall-mounted, 2-gang format makes it appropriate when the control needs to be installed at an accessible location rather than placed with other system equipment. The 15 dB attenuation range is useful for systems where sound must be reduced in measured increments while retaining a defined relationship to the system’s established level. Before selection, confirm that the installation uses a 70.7V system and falls within the stated 250 W rating.

Why Choose This Model

The E408-250 combines a high stated power rating with precise 1.5 dB steps. Instead of an unspecified adjustment range, it provides a documented 15 dB of total attenuation. This makes its available control range and increment size clear during system planning. The stainless steel plate, 2-gang size, and published dimensions also allow installers to assess physical compatibility before ordering. AtlasIED describes the attenuator as a solution for achieving clear sound control across different environments.

Installation and Integration

The attenuator is plate mounted and identified as a wall-mounted model. Its plate measures 4.56 inches high by 4.5 inches wide, or 11.58 by 11.43 centimeters. The specified depth is 2.51 inches, equivalent to 6.38 centimeters, so the available installation depth should be checked as part of the mounting plan. The 2-gang plate is made from stainless steel. The unit weighs 1.5 pounds, or 0.68 kilograms, while its listed shipping weight is 1.79 pounds, or 0.81 kilograms. For projects requiring rack placement, the source data identifies the E408-250-RM for rack mounting.

Performance Highlights

The core performance specifications are a 250 W power rating, compatibility with 70.7V audio systems, 15 dB of total attenuation, and adjustment in 1.5 dB steps. Together, these figures define the intended electrical application and the amount of level reduction available. The stepped adjustment format provides known attenuation increments rather than an unspecified control scale. Safety listings include UL813 and UL2043, giving integrators specific listing information to reference when evaluating the product for a project.

What Makes It Different

The defining combination is its 250 W rating and precision 1.5 dB adjustment steps within a wall-mounted, stainless steel 2-gang plate. The model’s complete dimensional information distinguishes it as a product that can be evaluated for installation space before deployment. Its documented total attenuation, plate material, safety listings, weight, and mounting format provide concrete selection criteria. The E408-250 is therefore differentiated by a focused specification set: 70.7V operation, high-power handling, stepped attenuation, and a plate-mounted control format.

Final Assessment

The AtlasIED E408-250 is a purpose-specific choice for a 70.7V audio system requiring a 250 W wall-mounted precision attenuator. Its 15 dB range and 1.5 dB steps make the degree of available control explicit, while the stainless steel 2-gang plate defines its installation format. Confirm the system voltage, required power rating, mounting depth, plate dimensions, and desired attenuation range before purchase. The product is backed by a warranty period of 60 months from the date of purchase.
