TheSTM2Z+is a simple but versatile preamplifier, offering a multifunction solution for installations where multiplevoice and music sources need to be mixed to two output zones. The stereo design with ten inputs allows connection for any type of audio source such as microphones, Bluetooth devices and various balanced or unbalanced line level audio sources.

Channel one to four are balanced inputs, allowing connection of microphone and line level audio sources. Channel1 feature LINE/MIC, phantom power and talk over for priority announcement and Channel 2~ Channel 4feature LINE/MIC and phantom power. The other inputs are three unbalanced stereo line inputs allowing connection of any line level audio sources.

An integrated Bluetooth receiver offers convenient wireless connection possibilities for mobile and portabledevices including laptops, smartphones and tablets.

A front panel 3.5mm jack allows monitoring MONO or STEREO input signal with MONITOR level dial.

Two master volume controls for the outputs of MONO (1-MONO) and STEREO (2-MONO/STEREO) includingSignal and Peak LED is located on the front panel, also accommodating each input mixing dial.
