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.

Switched WhisperTouch™ Impedance Matching Volume Controls
Switched WhisperTouch volume controls provide clear, distortion-free music reproduction for commercial distributed
systems or "Whole House" audio designs.
These volume controls feature impedance-matching (8 Ω versions only) to protect the amplifier and balance the audio
signal, fine-tune level control to adjust low listening levels to the perfect setting, and an easy-grip, low profile knob.
The knob features smooth detents and make-before-break contacts for smooth transition when changing volume
settings. Attenuation is accomplished in 10 steps. All models have frequency response of 20 Hz – 20 kHz (-3 dB, +0).
Units include an on / off switch and indicator light. An internal "smart" relay switch automatically puts speakers
into "stand by" mode making them "available" rather than indiscriminately active when the audio system is pow-
ered on. Simply touching the switch accesses audio. A modest sized indicator light provides quick visual status
– (green=standby, red=active) Models require a separate 18-gauge, 2 conductor stranded cable to power the
internal relay in addition to the loudspeaker cable. An external power supply, PS-M12, is recommended for 1–3
WhisperTouch units, or PS24-20 (See Page 64) for up to 18 units.
For installation, either a backless E.O. box or sealed box with 18 or 20 in3 volume (Carlon® B120A or equivalent)
is required. Standard or Decora plate styles and available colors vary by model – see chart for details. Decora trim
plates not included.

DAT Series Atlas Sound offers traditional autoformer controls to provide excellent stereo performance and maxi-
mum speaker-handling capability. Models include positive off and full-power pass through at the maximum setting.
Contacts are make-before-break for smooth transition. Models with 8 Ω impedance are suitable for residential stereo
and voice-coil circuit application. Models for 25V or 70.7V use provide level control in distributed constant-voltage
systems. Single-gang models mount standard E.O. boxes 21⁄2" deep. Includes both white and ivory knobs, inserts and
trim plates.
• Choose DAT8ST to Control Speaker Volume when Impedance Matching is Not Necessary Such as Single-pair
Installations or when Multi-channel Amplifiers are Used for Individual Zones. Combine DAT8ST with a Separate
Impedance-Matching Switching Device (AST Series) to Design a System with Multiple Loudspeaker Pairs.
• Choose DAT35ST70 for Control of Distributed Stereo Zones in 25V / 70.7V Systems.

Impedance-Matching Speaker Selectors
For use with 8 Ω Applications Only, NOT 70.7V Applications.
ASL-6A Impedance-matching loudspeaker switching system provides control of up to six loudspeaker pairs posi-
tioned in multiple room applications. All volume controls for each loudspeaker pair are located on the front panel
for easy access. Attenuation is accomplished in 10 steps. Units accommodate any combination of 8 Ω and/or 16 Ω
loudspeakers. Choose ASL-6A to control speakers in retrofit or pre-wire installations where speaker wiring goes
directly to the main equipment cabinet; not to individual volume controls. ASL model offers individual speaker volume
controls with individual A/B source selection and separate on / off controls for each loudspeaker pair. Unit features a
mar-resistant black finish. Dimensions are 17" Width x 15⁄8" Height x 57⁄8" Depth and can be shelf or 19" rack-mounted
(brackets included). Wire capacity is 14-gauge – 24-gauge.
AST-6 Impedance-matching loudspeaker switching system provides control of up to six loudspeaker pairs positioned
in multiple room applications. Controls for each loudspeaker pair are located on the front panel for easy access. Unit
accommodates any combination of 8 Ω and/or 16 Ω loudspeakers. Use AST Series to offer additional functionality to
systems using traditional (non-WhisperTouch®) volume controls such as the DAT8ST. AST devices include separate
on / off controls for each loudspeaker pair and one A-B source selector switch for overall system control. Units feature
a mar-resistant black finish. Dimensions are 17" Width x 15⁄8" Height x 57⁄8" Depth and can be shelf or 19" rack-mounted
(brackets included). Wire capacity is 14-gauge – 24-gauge.
