PRE ST 1

Permanent installations require solutions which offer a visually discrete design that blends into the background while still being flexible and versatile in their functions. You need to be able to connect different audio sources and manage them, to mute non-priority signals during announcements or emergency calls.

The PRE ST 1 is a 4-channel multi-functional stereo mixer preamplifier that allows users to mix 2 microphone/line sources together with an emergency line input and one of the 3 music sources available, including a Bluetooth receiver. These versatile connection options together with a four-level priority system, that combines contact closure inputs and VOX audio detection circuits, guarantees a seamless integration in almost any commercial audio application.

PRE ST 1 is equipped with two priority contacts: one for the emergency input, which mutes all the other signal sources, and one for the microphone inputs, which mutes the music signal sources. The stereo balanced line output includes a mono/stereo switch and separate tone controls for bass and treble. An automatic standby mode can also be activated in order to further reduce energy consumption when the device is not used.

The intuitive design of its control panel ensures an easy operation, with input and master volume controls, clear signal level and priority indications, and a practical music source selection and Bluetooth pairing activation via capacitive buttons. On the other hand, the clarity of the rear panel and the compact 9.5" format ensures that the preamplifier can be easily installed.
