FAQ
Which length should I choose?
For a small stage or home setup, 3 m is usually enough. Choose a longer cable when the amplifier, mixer or speaker is far from where you play or sing. This one is 3 m long.
Can I use it for studio monitors?
Yes, when both the interface or mixer output and the monitor input are 6.3 mm TRS jacks.
