Audio Cables for Camera & Production Use
Audio cables are the physical connections that keep your sound chain intact from microphone to recorder to speaker. Impulse Camera Store carries XLR microphone cables, TRS balanced cables, TRRS cables for camera and smartphone connections, instrument cables, adapter cables, and specialty production audio cables for film, broadcast, and studio recording applications. A quality cable is silent, flexible, and reliable — a cheap one costs you takes and time on set.
Buying Guide: Audio Cables for Production & Recording
XLR Cables
XLR is the professional standard for balanced audio transmission over distances — from microphone to mixer, mixer to recorder, or audio snake from stage to recording booth. The balanced signal path rejects electromagnetic interference (EMI), making XLR cables essential for any environment with lighting dimmers, motors, or other electrical interference. Standard XLR cables use a 3-pin connector. XLR cables come in lengths from 3 feet to 100 feet for different production scenarios.
TRS & TRRS Cables
TRS (Tip-Ring-Sleeve) 3.5mm cables carry stereo audio and are used for camera headphone outputs, some consumer microphone inputs, and audio interfaces. TRRS cables carry stereo audio plus a microphone signal — the format used by smartphone headset jacks. For connecting a microphone to a camera's 3.5mm input, a TRS cable is standard; for connecting to a smartphone, a TRRS cable is often needed. The difference matters — using the wrong cable type causes missing audio or recording from the wrong source.
XLR to 3.5mm Adapter Cables
Many video cameras only accept 3.5mm audio input while professional microphones output XLR. An XLR-to-3.5mm adapter cable bridges these two worlds. Note that these cables are passive — they don't provide phantom power for condenser microphones. If your microphone requires 48V phantom power, you'll need an active adapter or preamp between the XLR microphone and the camera's 3.5mm input.
Cable Quality & Shielding
Cable shielding quality determines how much electromagnetic interference reaches your audio signal. Braided or foil-shield cables with high-quality connectors (Neutrik XLR connectors are the industry standard) minimize noise pickup in demanding environments. For narrative film sets and studio use, invest in quality cables — the difference between a mediocre cable and a quality one is audible as background noise and self-noise in the recording chain.
What is the difference between TRS and TRRS audio cables?
TRS (Tip-Ring-Sleeve) carries balanced mono or unbalanced stereo audio. TRRS (Tip-Ring-Ring-Sleeve) adds a fourth conductor for a microphone signal — the format used by smartphone headset jacks. Connecting a TRS microphone to a TRRS-only smartphone jack may result in no audio or recording from the wrong channel. Many microphone adapters and adapters include TRRS versions for smartphone compatibility.
How long of an XLR cable do I need for a boom pole?
For most interior location work, a 10-25 foot XLR cable run inside or alongside a boom pole is sufficient. For larger sets with a mixer stationed far from the set, 50 or 100-foot runs may be needed. Longer cable runs are more susceptible to interference — use quality shielded cables and keep audio cables away from power cables when possible.
Can I use a 3.5mm cable to connect a professional XLR microphone to my camera?
Yes, with a passive XLR-to-3.5mm adapter cable, you can connect an XLR microphone to a camera's 3.5mm input. However, this doesn't solve the phantom power requirement for condenser microphones — you'll need an active adapter (like the Beachtek DXA series or Deity Connect box) that supplies 48V phantom power to the microphone while outputting a 3.5mm signal to the camera.
What audio cable should I use for a camera's headphone monitoring output?
Camera headphone outputs use a standard 3.5mm TRS connection. Any 3.5mm TRS cable or headphones with a 3.5mm plug will work. For longer monitoring runs on set, a 3.5mm extension cable provides enough length without quality loss. If your headphones use a 1/4" plug, a 1/4"-to-3.5mm adapter completes the connection.
