The Adastra US60 installation power amplifier boosts and extends PA systems with 100 V speakers. Its 100 V input allows parallel connection to 100 V speakers, while the mono output supports a 100 V line or an 8 Ω speaker load. Class D design delivers 60 W RMS.
The housing is 1U high and half-rack width. The speaker output connects via a removable terminal block, while the 24 V relay contacts allow muting via a fire alarm system. Rack-mounting hardware is included, and can be configured to install a single unit on a wall or beneath a worktop.
