XLR to XLR Cable: The Standard Audio Run, Done Correctly
Quick answer / TL;DR: Short answer: a standard XLR to XLR cable is male at one end and female at the other, wired straight (pin 2 hot, pin 3 cold, phases aligned). It connects a balanced source to a balanced input – mic to console, console to interface, interface to monitor. Male-to-male builds exist for specific panel-to-panel work but are not the default for microphones. Check phase at both ends if a channel sounds thin or hollow.
An XLR to XLR cable is the default audio connection – the straight run from one balanced device to another. It is also the cable where the subtle errors live: a phase inversion that reads as thin sound, a patch that crosses channels, and the occasional male-to-male build that is right for a panel and wrong for a mic. The cable is simple; the correctness is in the details.
This guide covers the standard configuration, how phase behaves across the run, and the patching practice that keeps a chain of XLR connections clean.
The Standard Configuration
| End | Connector | Typical device |
|---|---|---|
| Source end | XLR male (pins) | Microphone, line-out panel |
| Input end | XLR female (sockets) | Console, interface, monitor |
The male end carries the signal out; the female end receives it. A standard XLR to XLR cable is one of each, wired straight. When both device ends are the same gender (two females, a common panel scenario), the correct product is a male-to-male or a gender-change build – which is the exception, not the default.
Phase Across the Run
In a straight-wired cable, the phase relationship is preserved end to end – a waveform that rises on pin 2 at the source rises on pin 2 at the destination. A phase error enters the chain from a reversed cable, a crossed patch, or a device with a polarity switch – and it reads as thin, hollow, or 'out-of-phase' sound rather than silence. Diagnosing it: the channel works, but the tonality is wrong; a polarity flip at one end corrects it.
| Symptom | Likely phase cause | Fix |
|---|---|---|
| Thin, hollow sound on one channel | Reversed cable or crossed patch | Verify straight wiring; correct the patch |
| Two mics sound wrong together | Phase cancellation between mics | Flip polarity on one mic preamp |
| Single mic sounds fine alone, weak in mix | Comb filtering from a second source | Check the second channel's phase |
Patching Practice
- Patch one source to one input – a channel is a pair, not a bus
- Label patch runs in a chain so a crossed cable is a 10-second fix, not a hunt
- Keep patch cable lengths short and consistent – a tidy patch bay is a diagnosable patch bay
- A patch that crosses channels is the most common silent error in a stage box
When Male-to-Male Actually Appears
- Panel-to-panel where both ends are female
- Specific speaker-management and distribution builds
- Field-wire terminations where both connector ends are specified male
Per-build polarity conventions for male-to-male and panel cables vary by application; the knowledge base does not provide a panel-polarity standard. Confirm the intended polarity with the system design before specifying a non-standard gender build.
Real-World Applications
The stage box
Every mic and every DI is a straight XLR to XLR run from the stage to the stage box, patched one-to-one. The discipline is the labeling and the one-channel-per-patch rule.
The control room chain
Console out to interface to monitor is a chain of straight XLR runs – each link verified in phase, so the monitoring chain is summing, not canceling.
The phase hunt
A channel that sounds thin in the mix but fine soloed is a phase investigation – the cable and the patch are checked before the mic is blamed, because a reversed run is the usual cause.

Frequently Asked Questions
Is a standard XLR to XLR cable male to female?
Yes – the default is one male end and one female end, wired straight. Male-to-male and female-to-female are specific builds for panel and field work, not the standard run.
Why does my channel sound thin but still works?
That is the classic phase symptom – a reversed cable or a crossed patch inverts the phase without breaking the signal. Correct the polarity at one end and the tonality returns.
Can I use XLR to XLR for a microphone to an interface?
Yes – that is the standard microphone connection. The mic's male end plugs into the interface's female XLR input with a straight cable.
How do I verify a cable is wired straight?
Check the pinout at both ends – pin 2 should be hot and pin 3 cold at both ends of a straight cable. A continuity or phase checker confirms it; the spec sheet states it.
