The TSD-PA20VG is a cost effective mono amplifier for 4Ω and distributed constant voltage speaker systems. Applications include hallways and classrooms. The TSD-PA20VG is also a cost effective alternative for small projector systems as it can be used with as many as (16) 25/70/100V ceiling speakers (tapped at 1W each), plus the extremely small footprint allows for easy mounting.

For sound masking applications the TSD-PA20VG has the capacity to drive up to 34 masking speakers tapped at .5W each on a 70.7V line. Output is gain controlled from a potentiometer on the front panel with removable knob.

Unit requires Power Supply that is sold separately for proper function, multiple TSDs can be powered with one power supply based on current requirements. You must use the TSD24V2500MA power supply. For multiple TSD applications use the TSD Power Calculator to determine the proper power supply needed.

Through proven performance, patented VT Series fire protective signaling speakers have earned worldwide acclaim for service reliability. Inside every VT speaker is a small compression driver capable of high sound pressure levels, and the die-cast, water-sealed construction withstands vandalism, vermin, moisture, corrosion, and vibration during indoor or outdoor use.
An internal DC blocking capacitor enables the VT to work on supervised speaker lines, and speaker wiring terminates on a barrier strip. Optional mounting accessories are offered including: indoor and outdoor enclosures, a bi-directional housing, adapter plates and rings. Neutral Gray Finish

Through proven performance, patented VT/VTF Series have earned worldwide acclaim for service reliability. These cost-effective units offer compact size, functional flexibility, optimum intelligibility, effective sound distribution, and high-level output. All models contain a highefficiency compression driver with maximum acoustic conversion efficiency. (A quality which reduces number of units needed to attain specified sound pressure levels and provides substantial savings in amplification-power requirements and labor costs.) Die-cast, water-sealed construction withstands vandalism, vermin, moisture, corrosion, and vibration during indoor or outdoor use. Selection includes a basic 8-ohm version and 70.7 or 25-volt transformer models with DC blocking capacitor (C) where noted. All models terminate via barrier strips. VT Series models are surface-mount units; VTF Series are flush-mount units for recessed installation. VT Series mounts standard 4" E.O. Boxes; VTF Series mount 4" or 4 11/16" SQ backboxes and require model AR or MR adapter rings respectively (order separately) Optional mounting accessories are offered including: indoor and outdoor enclosures, a bi-directional housing, adapter plates and rings. Suffix model with color: Red (R) or Neutral Gray (N). Ex: VT-157UCS.
