Expand Your Commercial Audio Zones
The AtlasIED TSD-TXHL is a versatile high-to-low level converter designed to solve complex installation challenges. It allows integrators to tap into existing 4Ω, 25V, 70V, or 100V distributed speaker lines and convert that high-voltage signal back down to an unbalanced line-level output.
No Dedicated Wiring Required
This device is the perfect solution for system expansion. Instead of running new line-level cabling from the main headend to a remote location, you can simply tap off the nearest speaker line to drive a local amplifier in a new zone. The TSD-TXHL features an isolated transformer that ensures no measurable load is added to the existing speaker line, preventing impedance issues.
Passive & Adjustable Design
Because it requires no external power, the TSD-TXHL can be installed anywhere in the ceiling or rack. It includes an input gain adjustment switch and a variable output trim control, allowing you to perfectly match the signal level to the input sensitivity of your remote amplifier, such as AtlasIED's CP and PA series amplifiers.
