Lowell LPD-1500S Specifications

Model No’s.: LPD-1500S and LV-series

L-pad & Potentiometer Control Attenuators

Description

• ModelNo.LPD-1500S: Wirewound L-pad control provides a constant

1500 ohm load to the line or power source regardless of the control
setting. Attenuation is continuous with a stop at minimum and maxi­mum levels. It is mounted to a stainless steel wall plate with stamped
and filled dial scale, fluted black knob and mounting screws.

• LV-series: Potentiometer control with 50 or 5000 ohm impedance pro­vides economical volume level adjustment in systems with low power
circuits. Controls with wall plate are shipped mounted to a 1-gang stain­less steel plate. Controls for rackmount use (model no’s. ending with
“RM”) are shipped unassembled for installation to a rack panel (kit
includes potentiometer, 2” x 2” black adhesive dial scale (0-10), fluted
black knob and mounting hardware).

– ModelLV-50S(wallplate)andLV-50S-RM(rackmount): have

a 5W power rating and 50 ohm impedance. They’re ideal for use
with 4, 8 or 16 ohm voice coil circuits and are continuously vari­able with stop at minimum and maximum levels. Includes dial
scale (0-10) and fluted black knob.

– ModelLV-5K(wallplate)andLV-5K-RM(rackmount): have a

5W power rating and 5000 ohm impedance for application with
constant voltage 25V, 70V, or 100V loudspeaker systems. Atten­uation is continuous with no stops at minimum or maximum. In­cludes dial scale (0-10) and fluted black knob.
