AUDAC PRE116 audio preamplifier Bluetooth

Description

The PRE116 is a 6 channel stereo preamplifier containing a variety of input possibilities for microphone and line level audio signals, offering a possibility for a wide range of small to medium sized audio installations in various kinds of applications. It features two balanced mono inputs with phantom power and three band tone control allowing connection of microphones or line level signal sources. The switchable talkover function suppresses background music if a priority signal is present, making it suitable for paging or voice file announcements. The four stereo line level inputs are implemented as a balanced one fitted with XLR connectors and three unbalanced ones fitted with RCA connectors. Hereby, connection possibilities for a wide variety of line level sources is guaranteed. Additionally, an integrated Bluetooth receiver (mixed with Ch 3) and 3.5 mm jack connection on its front panel (mixed with Ch 4) are offering convenient wired or wireless connection possibilties for portable and handheld devices including laptops, smartphones and tablets. A priority mute contact suppresses all (nonpriority) music sources in case of contact closure, allowing to link autonomous alarm systems. Input volume control is done using the corresponding rotary dials on the front panel, while the output section features a 6-segment LED VU bar, a master volume control and 2-band tone control. Connections and input or output configurations such as gain adjustment and mono/stereo switching can be done through the provided controls on the back of the device.

Example setup with ARJ12P
For this application, we used a PRE series stereo preamplifier with a WP2xx series universal wall panel and connected them using an ARJ12P junction box. By connecting any WP2xx universal wall panel, we extended the functionality of the PRE series with a peripheral input with mixing functionality, Bluetooth functionality, or both. As a result, a simple PRE series application gains local input flexibility with such an elegant solution, with the addition of ARJ12p and a 24V power supply (PSD241 in this example).
