Tascam LM-8ST Stereo Line Input Mixer

The LM-8ST is a compact line mixer for installation, studio submixing, keyboardists or anyone who needs a mix of line signal sources. Eight stereo input sources like CD/MP3 players, tuners, instruments etc. can be routed independently to a pair of stereo outputs. For the second output the user can choose between pre and post-fader routing. Input and output level controls and metering keep signals under control. A microphone input is also provided for announcements or performance. Master bus inputs and outputs are available for cascading multiple units.

The LM-8ST is housed in a rugged rack-mountable chassis and has a built-in power supply (no AC adapter) for many years of safe and reliable operation.
