Owner’s Manual
1.3 What’s in your My PreSonus Account
Once you register your ioStation 24c , you will be able to download the following:
Studio One Artist recording software and content
Universal Control (necessary for firmware updates)
Visit http://my.presonus.com to register your
ioStation 24c and download your software and license.
1.4 Firmware Updates
PreSonus is committed to constant product improvement. As part of this
commitment, we offer periodic firmware updates that add features, improve
functionality, and resolve issues that are discovered in the field. Because
of this, it is highly recommended that you download Universal Control
from your My PreSonus account after registering your ioStation 24c.
Note: At the time of this manual’s publication, a firmware update is required for full
functionality of your ioStation 24c. You must download and install Universal Control and
run the firmware update on your unit.
During installation, you will be given the option to install various
PreSonus audio drivers. No driver installation is required for macOS.
Windows users must install the ioStation 24c audio driver.

1 Overview
1.4 Firmware Updates
ioStation 24c Audio Interface and Production Controllers
Owner’s Manual
Once installed, connect your ioStation 24c to your computer.
Universal Control will alert you if there is new firmware available for your
ioStation 24c. Clicking on the Update Firmware button will begin the
update process. This process can take up to five minutes. At the end of the
firmware update, you will be prompted to reboot your ioStation 24c.
Once rebooted, your ioStation 24c fader may require recalibration. This is an
automated process. Do not interfere with or interrupt the fader calibration process.
Note: One of the Operating Modes must be selected to perform a firmware update.

2.1 Back Panel Connections
Mic/Ins/Line inputs Your ioStation 24c interface
is equipped with high-quality XMAX microphone
preamplifiers for use with all types of microphones.
Both input channels on your ioStation 24c interface are equipped
with combo jacks. This convenient connector accepts:
•a ¼-inch line-level phone plug (for synthesizers, signal processors, etc.)
•a ¼ passive instrument cable (for guitar, bass, etc.),
•or an XLR plug.
Please note: As with any audio input device, plugging in a microphone or an instrument,
or turning phantom power on or off, will create a momentary spike in the audio output.
Because of this, we highly recommend that you turn down the channel trim before
changing connections or turning phantom power on or off. This simple step will add
years to the life of your audio equipment.
Headphone Output. The rear-panel headphone output mirrors the same streams as
the Main left/right outputs.
Main Outs. These are the Main outputs for the ioStation 24c. The output level of the
Main outputs is controlled by the Main level control on the front of the unit. Playback
streams 1 and 2 are routed to these outputs.
USB C Port. Use this port to connect your ioStation 24c to your computer. While
the ioStation 24c connects using USB C, it is fully compatible with USB 2.0 and 3.0
connections. Use the USB C to A cable that came with your ioStation 24c if your
computer has a USB 2.0 or 3.0 connection rather than a USB C connection. Do not
connect your ioStation 24c to a USB 1.1 or lower connection on your computer.
Footswitch. Use this port to connect a footswitch to your ioStation 24c to trigger
start/stop or recording punch-ins.

Input Gain Controls. These knobs provide 80 dB of variable gain
for Mic and Instrument; 40 dB of range for Line (-20 to +20)
Clip Indicators. The red Clip LED will illuminate when your input signal reaches -0.5
dBFS. At this level, the signal will begin to overload the analog-to-digital converters
and exhibit signs of clipping. Use the gain controls to keep the signal below this level.
Line. Use the Line switch to toggle between instrument-level
and line-level sources. It will light up blue when selected; light off
indicates high-impedence instrument-level compatibility.
48V The ioStation 24c provides 48V phantom power for the microphone
inputs. Pressing the 48V button switches phantom power on and off
for all microphone inputs; the button will illuminate in blue when
phantom power is available on the microphone preamplifiers.
WARNING: Phantom power is only required for condenser microphones and can
severely damage some dynamic mics, especially ribbon mics. Therefore, switch
phantom power off when it is not required. Consult the user documentation
that came with your microphone before engaging phantom power.
XLR connector wiring for phantom power:
Pin 1 = GND Pin 2 = +48V Pin 3 = +48V
Sync LED. This light indicates if your ioStation 24c is in sync with your computer.
When no sync is available, this light will flash red.

Mix. The Mix knob allows you to blend your input signals with the playback streams
from your computer so that you can monitor your input signals without any latency
(delay). If the knob is positioned at 12 o’clock, the input signal and the playback
stream will be equally balanced. Turning the knob to the left will increase the level
of the input signal relative to the playback stream; turning to the right will increase
the level of the playback stream relative to the input signal as illustrated below:
Mixer PlaybackInputs

Headphone Level. This knob controls the level of the rear panel headphone output.
Main. The main knob controls the output level for the main left/right outputs on the
back of your ioStation 24c and has a range of -80 dB to 0 dB. This control provides
attenuation only.
Mute. This button mutes the Main Outputs. The headphone output is unaffected by
this mute switch.

3Connecting to a Computer
Before connecting your ioStation 24c to a computer, please visit
www.presonus.com to verify the latest system requirements.
Note: The speed of your processor, amount of RAM, and capacity, size, and speed of your
hard drives will greatly affect the overall performance of your recording system. A faster
processor and more RAM can reduce signal latency (delay) and improve overall
performance.
The Windows ASIO driver, and Universal Control installer for macOS and
Windows are available for download from your MyPreSonus user account.
To begin, you must first visit http://my.presonus.com, create or log into your
user account, and register your ioStation 24c. Once registered, all software
downloads will be available from within your MyPreSonus user account.
3.1 Installation for Windows
Download the Universal Control installer from your MyPreSonus account.
Connect your ioStation 24c to an available USB C, 2.0, or 3.0 port and
launch the installer. The installer will take you through each step of the
installation process. This application will install the ASIO and WDM drivers,
as well as Universal Control. Please read each message carefully.
It is recommended that you quit all applications before you start the installation.
The Universal Control installer will take you through each step
of the installation process. Please read each message carefully
so that you do not connect your ioStation 24c too soon.
Power User Tip: It is recommended that you temporarily disable or turn off any anti-virus
programs you have running to prevent installation issues.
3.1.1 Universal Control (Windows)
Universal Control is a powerful hardware-management application for all
PreSonus interface products. It allows you to view any PreSonus interface
product connected to your computer or your computer’s network.
When Universal Control is launched, you will see the Launch window.
From this window, you can manage all the ASIO driver settings.
Sample Rate. Changes the sample rate.
You can set the sample rate to 44.1, 48, 88.2, 96, 176.4, or 192 kHz. A higher
sample rate will increase the fidelity of the recording but will increase the file
size and the amount of system resources necessary to process the audio.

Block Size. Sets the buffer size.
From this menu, you can set the buffer size. Lowering the buffer size will
lower latency; however, this will also increase performance demands
on your computer. In general, you will want to set the buffer size as
low as your system can safely support. If you begin to hear pops, clicks,
or distortion in your audio path, try raising the buffer size.
Loopback (Windows only). The ioStation 24c ASIO driver provides
two loopback streams to record audio from one application
to another. See Section 3.1.2 for more information.

3.1.2 Loopback Recording (Windows only)
The Windows drivers for the ioStation 24c provides two virtual streams
that allow you to record the output of one audio application in another
application. Loopback can be useful in a variety of situations:
•Recording the audio from a video game or YouTube
video for a podcast or livestream.
•Recording a vocal in real time over a karaoke track
played from a web browser or media player.
Power User Tip: Because the ioStation 24c is a class compliant Core Audio device, these
virtual streams are not available in macOS. However, there are several third-party
applications that provide this functionality in macOS.
From Universal Control, you can enable or disable Loopback and pick
the streams on which the loopback audio will be recorded.
When Loopback is enabled and“Merge Loopback with 1/2” is selected,
the audio from another application will be recorded with the audio
source connected to analog inputs 1 and 2 on your ioStation 24c.
Media Player
Web Browser
Etc.
When Loopback is enabled and“Dedicated Loopback Inputs” is selected, the audio
from another application will be recorded on the last pair of driver inputs (3/4).
Media Player
Web Browser
Etc.
Power User Tip: When using either option, you will need to select Outputs 1 and 2 in the
audio application you want to record. Make sure to select Outputs 3 and 4 in the audio
application in which you’re recording to avoid a feedback loop.
