Connections & Hardware
Q: What MIDI footswitch do you recommend?
A: BIAS MINI is compatible with any standard MIDI controller that sends MIDI PC (Program Change) or MIDI CC (Control Change) messages. See the user manual for details.
Q: Could the 300W amplifier damage my speaker cabinet?
A: BIAS MINI provides 300W RMS @ 4 ohms and 150W RMS @ 8 ohms. Use caution at high volumes. Do NOT connect to powered speakers, or grounded equipment (effect pedals, DI boxes, audio interfaces, mixers) as this could cause damage.
Q: What impedance should my speaker cabinet be?
A: BIAS MINI uses a Class D power amp and works with any single 4, 8, or 16 ohm speaker cabinet. Unlike tube amps, you do not need a speaker connected to use the direct output or headphones.
Q: How do I connect FX pedals using the FX loop?
A:
- Use two mono TS 1/4" cables.
- Connect MINI's Send to the input of your effect unit.
- Connect the output of your effect unit to MINI's Return.
For more details, including integrating BIAS FX software, see: How to Connect BIAS MINI to BIAS AMP 2 / BIAS FX
Q: Can I connect to an external power amp without a speaker cabinet?
A: Yes. Unlike tube amps, BIAS MINI doesn't require a speaker to function. Use the Line Output or FX Send to connect to external gear (recorder, power amp, PA mixer).
Q: Can I use a 1/4" TS cable with BIAS MINI Bass?
A: Yes. The Speaker Output on BIAS MINI Bass accepts both 1/4" TS and speakON cables.
Recording & Audio
Q: Can I use BIAS MINI as an audio interface in my DAW?
A: No. BIAS MINI does not have an ASIO driver and cannot be used as an audio interface. To record, connect the XLR output to your audio interface, or mic the speaker with a dynamic/condenser/ribbon microphone. When using BIAS AMP 2 Desktop with MINI via USB, we recommend using the standalone version to avoid MIDI interference from your DAW.
Q: Can I connect the XLR output to a device with 48V phantom power?
A: No. Do NOT connect the XLR output to equipment with 48V phantom power enabled (mixers, mic preamps). This may damage your BIAS MINI.
Q: Does the BT-4 Bluetooth Pedal work with BIAS MINI?
A: No. The BT-4 is iOS-only and not compatible with BIAS MINI. Use the BFS4 wired footswitch instead.
