Knobs

Headphone Output Controls

One volume knob per pair of headphones, so everyone at the table can set their own listening level.

tip: Always start these low and bring them up gradually to avoid a nasty surprise; match each knob to the headphone sensitivity you set under settings > Outputs > Headphones for consistent levels.

show text from manual

Four independent level knobs labelled 1-4 that set the volume of each of the four rear headphone outputs separately.

Rotary Encoder

The main jog dial — turn it to set speaker volume or tweak whatever value you've tapped on screen, press it to cycle virtual channels, and hold it to mute one.

tip: Tap a virtual channel's on-screen meter first, then turn the encoder — it becomes that channel's volume fader. A top-of-screen icon shows your current monitor level.

show text from manual

A push-and-turn dial that controls the monitor/speaker output level, adjusts on-screen values (gain, virtual faders, processing parameters), scrolls through virtual channels, and mutes the selected virtual channel when pressed and held.

Sliders & faders

Channel Faders

These are the volume sliders for your channels — push up to make a source louder in the mix, pull down to make it quieter.

tip: The thick white line just past halfway is 'unity gain' — a good starting point. If a channel is too quiet there, raise its preamp gain in the channel setup rather than shoving the fader higher, to keep noise low.

show text from manual

Six broadcast-quality physical volume sliders that set how much of each assigned channel is sent to the outputs. Their positions mirror in real time on the touchscreen. Three additional virtual faders exist on screen.

Buttons

Record Button (REC)

Your one-touch record control. A short press pauses, and press-and-hold stops (in the default 'Press to Pause' mode).

tip: You can flip it to 'Press to Stop' mode under settings > Display > REC Button. Minimum recording length is three seconds before it will let you stop.

show text from manual

Starts, pauses, and stops recording to the connected microSD card or USB storage. Turns green when storage is ready, red while recording, orange when paused.

Channel Buttons

Press the button above a fader to bring up everything about that channel on the touchscreen — what's plugged in, how loud it is, and how it's processed.

tip: The button colour matches the channel colour you assign, so you can colour-code your host, guests, music, and callers for quick visual reference.

show text from manual

Six coloured buttons, one above each physical fader, that open that channel's setup screen (source selection, gain, processing, effects, routing).

Mute Buttons

Press to silence a channel in the mix and the recording. The sound still exists at the input stage, so you can keep adjusting its gain while it's muted.

tip: Pressing a channel's Mute and Listen buttons together activates 'Back Channel' mode, letting you talk off-air with a guest.

show text from manual

The red button under each physical fader mutes that channel on the output. Muted channels glow red on the virtual mixer.

Listen Buttons

Press to privately listen to just one channel in your own headphones (output 1) — useful for checking a mic without disrupting the show.

tip: Choose 'After-fader' or 'Pre-fader' listen under settings > Outputs > Listen. Don't leave all Listen buttons engaged, or you may miss unexpected audio that's still being recorded on unmonitored channels.

show text from manual

The green button under each physical fader solos that channel to headphone output 1 only, so the host/producer can monitor it in isolation without affecting the recording.

SMART Pads

Programmable buttons that fire off jingles and sound effects, morph a voice, or perform combo mixer moves with a single tap.

tip: Two bank buttons give you eight banks of eight pads — 64 total actions. Set a pad to 'Latching' to keep an effect on until pressed again, or 'Momentary' so it only works while held.

show text from manual

Eight backlit trigger pads, each mirrored on screen, for launching sounds, voice effects (reverb, echo, megaphone, robot/pitch/disguise), mixer actions (Censor, Trash Talk, Fade, Back Channel, Ducking), MIDI messages, or CallMe quick dials.

Bank Switching Buttons

Flip through pages of pads so eight physical pads can hold many more sounds and actions.

tip: Group related sounds per bank — e.g. one bank for intro/outro music, one for stingers, one for voice effects — so you can find them fast during a live show.

show text from manual

Two buttons that page the eight SMART Pads through eight separate banks, for a total of 64 assignable pad functions.

Display & indicators

5.5" HD Touchscreen

This is where you see and control almost everything — tap channels to set them up, watch your levels, and dive into menus by tapping the settings cog.

tip: Tap a fader's on-screen level meter to select it, then use the rotary encoder for fine control — handy for the three virtual faders that have no physical slider.

show text from manual

The primary color touchscreen that displays the mixer, level meters, channel setup, processing editors, settings menus, SMART Pad grid, and recording playback.

Side panels

Buttons

Power Button

Turns the RØDECaster on and off.

tip: If you see an insufficient-power warning, the unit isn't getting the required 30W USB-C PD — use the supplied adapter or a battery bank rated 15V/2A.

show text from manual

The red button on the rear that powers the unit on and off. It sits beside the dedicated USB-C power port.

Jacks & connectors

microSD Card Slot

Slide in a fast microSD card to record your show straight to the device with no computer needed.

tip: You can record to a microSD card and a USB drive at the same time for an instant backup. Formatting erases everything on the card, so back up first.

show text from manual

Accepts a microSD card (100MB/s or faster; microSDHC/microSDXC recommended) for on-board multitrack or stereo recording.

USB 1 Input

Connect your main computer here — it carries both your primary audio and a separate 'Chat' channel for apps like Discord, and it's the only port that does multitrack over USB.

tip: Turn multitrack off for browser-based streaming (like restream.io) on Windows, or use USB 2 instead, since browsers may not recognise the multitrack device.

show text from manual

USB-C interface presenting 'RØDECaster Pro II Main' (stereo or 16-channel multitrack) and 'RØDECaster Pro II Chat' devices to a computer; supports microSD data transfer, multitrack output, and the RØDECaster App.

USB 2 Input

Connect a phone, tablet, second computer, or a RØDE USB mic here — it's the port built for mobile gear and calls.

tip: For iPhones/iPads with a Lightning port, use a RØDE SC15 or SC19 accessory cable (a plain charging cable won't work), and keep mix-minus on to avoid callers hearing themselves echo.

show text from manual

USB-C interface presenting the 'RØDECaster Pro II Secondary' device; MFi-certified for iOS, optimised for mobile devices and RØDE USB microphones, with mix-minus on by default.

1/4-inch Balanced Line Outputs

Plug your speakers in here to hear the mix out loud in the room.

tip: Use balanced TRS cables to avoid hum, and enable Auto-mute Output in settings > Outputs > Monitor so the speakers cut when a mic fader is up, preventing feedback.

show text from manual

A pair of balanced ¼-inch TRS outputs, labelled left and right, for connecting studio monitors or speakers. Level is set by the front rotary encoder.

Dedicated USB Power Port

This is where power comes in — use the included adapter, or a strong USB-C battery pack for portable use.

tip: Expect roughly one hour of runtime per 10Wh of battery capacity, so a big power bank gives about ten hours away from mains power.

show text from manual

USB-C input for the supplied power supply; requires 30W USB-C PD (15V, 2A). Can run from a compatible power bank.

Ethernet Port

Plug in a network cable for a rock-solid internet connection, especially for internet calls.

tip: For CallMe, a stable wired Ethernet connection generally beats Wi-Fi for consistent, low-latency call quality.

show text from manual

Wired network connection for firmware updates and for the RØDE CallMe remote-calling feature.

1/4-inch Headphone Outputs

Four headphone sockets so up to four people can each plug in and hear the show.

tip: If your headphones use a 3.5mm plug, use a ¼-inch adaptor like the RØDE HJA-4. Hosts should always use output 1 since the Listen buttons only solo to that one.

show text from manual

Four independent ¼-inch headphone jacks, each fed by its matching front level knob. Output 1 is where soloed/Listen audio is heard.

XLR/TRS Neutrik Combo Inputs

Your main plug-in points for microphones, guitars, keyboards, and drum machines — the same four sockets handle all of them.

tip: The Revolution Preamps are so quiet you should NOT use an inline lifter/booster (like a Cloudlifter) — it would only add noise. Adjacent inputs can be stereo-linked (1+2, 2+3, or 3+4) for stereo sources.

show text from manual

Four Neutrik combo jacks (inputs 1-4) accepting XLR mics (including phantom-powered condensers) or ¼-inch TRS/instrument connections, driven by RØDE's ultra-low-noise Revolution Preamps. Assigned to faders 1-4 by default.
