Atlas Sound FAP42T Volantino

Industry Standard Auto Transformer

AT Series

  UL listed high-quality auto transformer series provides the advantages of excellent frequency response, 

low insertion loss and reliable performance for volume control application in 25V and 70.7V systems. Attenuation is 
accomplished in ten steps plus positive off position. (No stop between maximum and off position to prevent switch 
damage). Contacts are silver plated for noise-free operation. Includes stainless steel plate, stamped and filled dial 
scale with skirted black knob.

Auto Transformer with Precision Level Control

E408-100

  Specially designed for attenuation in masking and sound reinforcement systems where fine tuning of level 

control is required. The 

E408-100

 employs a ten-position, non-shorting rotary switch without stop. Attenuation rate is 

1.5 dB per step. (All other specifications are the same as the 

AT Series

 including the UL listing).

Priority Paging Option

PA Series

  Priority paging feature bypasses the effect of the attenuator to provide program level selection of  

individual emergency and paging signals at the amplifier. This option is available on all 

AT Series

 attenuators. The 

SPDT relay is operated with 24VDC at 10 mA. Includes protective relay cover to ensure lasting trouble-free perfor-
mance. (All other specifications except for dimensions are the same as AT

 

Models.)

Rack Mount Option

RM Series

  For attenuation convenience of rack-mounted equipment in cabinets and consoles, the 

AT Series 

and 

E408 Series 

attenuators are available without mounting plate for rack panel installation. Attractive matte black polycar-

bonate dial scale overlay with adhesive backing replaces the mounting plate, skirted black knob included. Overlay size 
is 2" square (51 mm). (To order, simply add RM after the selected attenuator model number. Example: 

AT10-RM

 or 

AT10-PARM

.) (Dial scale overlays to retrofit existing installations are available, see hardware section Model 

HX23

.) 

For easy rack mounting of 

RM Series 

attenuators, see model 

ATPLATE-052

, Section 4, page 54.
