# What Audio Mixers and Interfaces Do You Use?

Quick Answer: GarlicVideo's Orlando podcast studio uses professional USB audio interfaces (Focusrite Scarlett 4i4, Universal Audio Apollo Twin, MOTU M4) and digital mixers (Rodecaster Pro II, Behringer X32) for podcast recording, providing multiple microphone inputs, individual channel control, zero-latency monitoring, and broadcast-quality 24-bit/48kHz recording capabilities.

Professional USB Audio Interfaces

USB audio interfaces convert analog microphone signals into digital audio your computer records, serving as the critical link between professional microphones and recording software. Quality interfaces dramatically impact final audio quality through superior preamps, converters, and low-noise circuitry.

The Focusrite Scarlett 4i4 (3rd generation) represents our primary interface for 2-3 person podcast setups. This $230 interface provides four microphone inputs with excellent Scarlett preamps, 24-bit/192kHz recording capability, direct monitoring for zero-latency playback, and industry-leading reliability backed by Focusrite's professional reputation.

Universal Audio Apollo Twin ($700-$900) serves premium podcast productions requiring absolute maximum audio quality. The Apollo's Unison preamps model classic recording consoles and the onboard DSP processing provides professional effects (EQ, compression, de-essing) in real-time during recording, creating polished podcast audio that requires minimal post-production.

MOTU M4 ($230) offers alternative professional quality with best-in-class converter specifications and incredibly transparent preamps for podcasters preferring uncolored, natural voice reproduction. The M4's LCD meters provide precise visual monitoring of recording levels across all inputs simultaneously.

Podcast-Specific Digital Mixers

The Rodecaster Pro II ($700) revolutionizes podcast production through integrated mixing, recording, sound effects, multi-track recording, and physical controls specifically designed for podcast workflows. This specialized podcast production console combines audio interface functionality with mixing capabilities in an intuitive, purpose-built package.

Eight motorized faders control microphone levels, music, sound effects, and guest inputs independently. Physical buttons trigger sound effects, jingles, or transitions instantly during recording—no mouse clicking or keyboard shortcuts required. This tactile control improves live recording flow and creativity.

Built-in processing includes professional compression, noise gates, de-essers, and EQ on every channel, polishing audio quality automatically without requiring technical mixing expertise. Presets for common microphones (Shure SM7B, Rode PodMic, etc.) optimize settings instantly.

Multi-track recording captures each microphone, music source, and sound effect on separate audio files, providing complete post-production flexibility to adjust levels, remove mistakes, or rebalance mix after recording completes.

The Rodecaster Pro II particularly suits podcasters wanting simplified production workflow, integrated sound effects capabilities, or professional results without extensive audio engineering knowledge.

Multiple Input Capabilities

Podcast formats requiring 3-5 simultaneous microphones demand interfaces with adequate input channels. Our Focusrite Scarlett 18i20 (eight microphone preamps) handles large panel podcasts or roundtable discussions where numerous participants record simultaneously.

Behringer X32 digital mixer provides 32 input channels with sophisticated routing, making it ideal for complex podcast productions involving multiple microphones, music beds, remote callers, and live audience interaction. This professional console costs $2,500+ but delivers broadcast facility capabilities.

Each microphone input includes independent phantom power switches (required for condenser microphones but potentially damaging to ribbon mics), gain controls for optimal level setting, and direct monitoring paths for zero-latency playback to participants' headphones.

Professional interfaces also provide instrument inputs (1/4" jacks) for connecting guitars, keyboards, or other instruments when podcast content includes musical elements or demonstrations.

Preamp Quality and Clean Gain

Preamp quality determines how cleanly interfaces amplify quiet microphone signals to robust recording levels. Superior preamps provide ample clean gain without introducing noise, hiss, or distortion—crucial for dynamic microphones like Shure SM7B requiring substantial amplification.

The Focusrite Scarlett preamps deliver 56dB of gain, adequate for most podcast microphones including SM7B when using proper microphone technique. The Universal Audio Apollo preamps provide 65dB of extremely clean gain, eliminating any noise concerns even with gain-hungry dynamic microphones.

Lesser audio interfaces (sub-$100 models) often provide insufficient clean gain, forcing you to boost levels during editing which amplifies noise and creates harsh, unprofessional-sounding audio. Professional interfaces record clean, noise-free audio at proper levels from the start.

Preamp modeling in Universal Audio interfaces recreates famous mixing console preamps (Neve, API, Universal Audio) that impart subtle harmonic characteristics. These vintage tones add professional polish and warmth that flatter podcast voices.

Direct Monitoring and Latency

Direct monitoring routes microphone signals straight to headphones before computer processing, eliminating the delayed echo (latency) that occurs when monitoring audio after computer round-trip processing. This zero-latency monitoring allows natural conversation without the disorienting delay that makes podcasting difficult.

All our professional interfaces include hardware direct monitoring with mix controls balancing between direct microphone signal and computer playback. This flexibility lets you hear yourself with zero latency while simultaneously monitoring pre-recorded music beds or intro audio from your computer.

Latency becomes problematic above 10-15 milliseconds, creating noticeable delay between speaking and hearing yourself. Professional interfaces with direct monitoring eliminate this issue entirely, enabling natural, comfortable podcast recording.

Software monitoring through DAW applications can work when buffer settings are optimized, but hardware direct monitoring provides simpler, more reliable solution requiring no software configuration or computer performance optimization.

Converter Quality and Bit Depth

Digital converters in audio interfaces determine how accurately analog microphone signals translate to digital recordings. Professional converters in quality interfaces preserve subtle vocal nuances, dynamic range, and frequency detail that lesser converters lose or distort.

All our podcast interfaces record at 24-bit/48kHz minimum—broadcast quality specifications ensuring professional results. The 24-bit depth provides enormous dynamic range (144dB theoretical) preventing any concerns about distortion from loud moments or noise from quiet passages.

48kHz sample rate matches video production standards and broadcast specifications, ensuring compatibility when combining podcast audio with video content or delivering to professional platforms requiring specific technical standards.

Higher sample rates (96kHz, 192kHz) provide minimal audible benefit for voice-focused podcast content. The 48kHz standard delivers complete professional quality while keeping file sizes manageable and computer processing requirements reasonable.

Multiple Headphone Outputs

Podcast recording requires each participant to monitor audio through headphones. Professional interfaces provide multiple headphone outputs with independent volume controls, allowing each participant to adjust their monitoring level without affecting others or the recorded audio.

The Rodecaster Pro II provides four headphone outputs with individual level controls and independent mix capabilities—each participant can customize their monitoring balance between their own microphone and other participants' voices.

Focusrite Scarlett interfaces include dedicated headphone outputs plus the ability to use main monitor outputs for additional headphone distribution through headphone amplifiers when recording larger groups.

Headphone monitoring quality varies significantly between interfaces. Professional interfaces drive headphones to adequate volume without distortion even with higher-impedance studio headphones, while consumer interfaces often provide insufficient power for professional monitoring.

Interface Connectivity and Computer Compatibility

USB-C connectivity in modern interfaces (Focusrite Scarlett 3rd generation, MOTU M4) provides reliable, fast connection to computers while drawing bus power from the computer itself—no external power supply needed for portable setups.

Thunderbolt connectivity in premium interfaces (Universal Audio Apollo) provides higher bandwidth supporting more simultaneous channels and lower latency monitoring, though requiring computers with Thunderbolt ports (many modern MacBooks, fewer Windows laptops).

Driver software compatibility varies by interface. Focusrite and MOTU interfaces offer class-compliant operation on Mac computers (working without driver installation) plus optimized drivers for Windows. Universal Audio requires driver installation but provides sophisticated control software managing the interface's advanced features.

Output Routing and Monitoring

Beyond recording inputs, interfaces provide output routing for studio monitors (speakers), headphones, and sends to other equipment. Flexible output routing accommodates different monitoring preferences and technical workflows.

Main outputs connect to studio monitors for playback review between recording takes. The volume control on the interface provides convenient adjustment without reaching for computer volume controls.

Separate headphone outputs with independent volume controls prevent the common frustration where adjusting speaker volume affects headphone levels or vice versa. This separation accommodates different monitoring scenarios throughout recording sessions.

Insert sends on advanced interfaces allow connecting external processing equipment (hardware compressors, EQs) into the recording signal chain for podcasters preferring analog processing over software effects.
