Note that tube microphones typically have external power sources and can easily connect to and send signals to guitar amps as long as they're powered.Īs for phantom-powered or DC-biased microphones, we must find alternative ways to supply the power needed. So how do we power active microphones that are connected to a guitar amplifier? We must provide the necessary power by other means. This power is typically provided by DC bias voltage, phantom power, or an external power supply, none of which a guitar amplifier provides. With passive microphones (moving-coil dynamics and most ribbon dynamics), the signal is transferred without any need for external power.Īctive microphones (all condensers and some ribbon mics), on the other hand, do require external power. Having a signal transfer from the mic to the amp is another. The Ring of the TRS plug would be nullified in the amplifier's TS jack.Ĭonnecting a microphone to a guitar amp is one thing. So long as the Tips and Sleeves of the connections connect, there shouldn't be any issues. This is because microphones send mono balanced audio. It's important to note here that an XLRF – 1/4″ Tip-Ring-Sleeve would also probably work, even though the amplifier plug is designed for Tip-Sleeve. XLRF to TS cable: this is a cable of any length that has an XLRF at one end and 1/4″ TS plug at the other.Įxample: Tisino XLRF to 1/4″ TS Adapter (link to check the price on Amazon).There are two main adapter styles for this: This adapter requires a female XLR at one end and a 1/4″ TS (or, alternatively, a TRS) at the other end. Therefore, to connect a microphone to a guitar amplifier, we must have an adapter cable to connect the microphone to the guitar amp. Microphones typically have balanced XLR outputs, while guitar amps almost always have unbalanced 1/4″ Tip-Sleeve inputs. We'll also discuss the issues once a microphone is connected to a guitar or bass amp.Īdapting An XLR Microphone Cable To 1/4″ TS In this article, we'll go over the cable adapters/wiring required to connect a mic to a guitar or bass amp. If using an active mic, ensure a power source is put in-line between the mic and amp. Note that TRS would also work but is not the ideal connection.
How do we plug a microphone into a guitar or bass amp? To plug a mic into a guitar/bass amp, we need to adapt the mic cable to a TS (tip-sleeve) connector and insert the TS into the amp input. You could be in a jam space without a PA system or be looking to add crunchy distortion (and other effects) to your vocals. Some situations may call for plugging your mic(s) into a guitar or bass guitar amplifier.
