Tascam LM-8ST - Rack Mountable Line Mixer

Yes, the LM-8ST includes one dedicated microphone input for announcements or speeches. However, it is primarily designed for line-level sources.

The LM-8ST features balanced 1/4" TRS inputs and balanced XLR outputs. For best results and to minimize noise, use balanced TRS cables for inputs and balanced XLR cables for outputs.

Yes, each pair of 1/4" TRS inputs features a switch allowing you to select between +4 dBu and -10 dBV levels, providing compatibility with a wide range of audio gear.

This refers to the ST2/AUX output. 'Pre-fader' means the signal level sent to this output is determined before the main channel faders, which is useful for sending a separate monitor mix. 'Post-fader' means the signal level is determined after the main channel faders, similar to the main ST1 output, and is often used for effects sends.

The LM-8ST has eight pairs of balanced 1/4" TRS inputs, allowing you to connect up to eight individual line-level stereo sources or sixteen mono line-level sources.

The LM-8ST is excellent for submixing multiple line-level instruments like keyboards or drum machines, or for combining stereo sources. For full band mixing, especially with multiple microphones, you would typically use it in conjunction with a larger mixing console.

The LM-8ST requires an external power adapter, which is typically included. Please refer to the unit's power input specifications for voltage and current details.

Ensure the unit is powered on. Check that all input sources are connected correctly and sending a signal. Verify that the input levels are set appropriately (+4 or -10 dBV) and that the master volume is turned up. Check that the output cables are securely connected to the receiving device.

Ensure all equipment is properly grounded. Try using balanced cables for all connections. If using unbalanced sources, check their output grounding. Avoid running audio cables parallel to power cables. Try a different power outlet.

Check the input source levels. Ensure the input level switch on the LM-8ST is set correctly for the source's output level (+4 dBu for professional, -10 dBV for consumer). Turn up the master volume control.

Ensure a microphone is properly connected via XLR to the Mic In jack. Verify that the microphone itself is functional and that any necessary phantom power (if required by the mic, though the LM-8ST doesn't provide it) is supplied externally. Check that the input source is intended for microphone-level signals if using a dynamic mic.
