Overview: The PreSonus StudioLive 24.4.2AI is a 24-channel
digital mixer that can be used for live sound or recording. Each of the 24
channels have an XLR balanced mic input and a balanced 1/4" TRS input. Powerful new software lets you control the
StudioLive 24.4.2AI remotely from a laptop, iPad, iPhone, or iPod touch, as well
as create and enhance dynamic recordings.
Active Integration: The StudioLive 24.4.2AI features Active
Integration, which combines a powerful, 32-bit floating-point DSP, wireless and
wired networking, USB 2.0 connectivity, and proprietary software to give you a
new level of live sound and studio mixing capabilities. The StudioLive AI-series
digital mixers include Wi-Fi remote control, as well as standard Ethernet
communication and networking. Coupled with high-quality components and massive
amounts of DSP processing, Active Integration provides a complete, networked,
and integrated system.
Inputs: The StudioLive 24.4.2AI is equipped with the following
- 24 Mic/Line Inputs: Channels 1 through 24 are equipped with balanced female XLR mic connectors with Class A XMAX
preamplifiers and balanced 1/4" line inputs. Each channel is controlled by a
- Inserts: Each input channel has a direct-insert point
with unbalanced 1/4" connectors. These can be used for external processors
(compressors, EQs, filters, de-essers).
- 2 AUX Inputs: There are 2 line-level, balanced stereo
auxiliary inputs (four 1/4" TRS inputs--2 left/mono and 2 right). These can
be generally used as effects returns, but they can also be used for any
line-level source, such as a keyboard.
- Talkback Mic Input: A female XLR input is provided for
connecting an external talkback microphone. It has the same high-quality
XMAX preamp that is found on the channel mic inputs. A rotary trim control is
provided to adjust the gain of the Talkback input. (If desired, the talkback
input can even be selected as a recording input.)
Outputs: The StudioLive 24.4.2AI has the following outputs:
- Mains: The separate left and right main outputs have
balanced male XLR connectors and balanced female 1/4" TRS connectors. There
is also a balanced male XLR mono output which carries a mono, summed version
of the stereo signal from the main bus.
- Main Output Trim: Rotary knobs on the rear
control the maximum output level of the XLR and TRS main outputs, and
can be attenuated to -40dB and boosted up to 0dB.
- Tape In/Out: Stereo RCA inputs and outputs are supplied
for connecting a tape deck, CD player, or other consumer device. The
tape-input level is controlled by the 2 Track In knob on the top panel.
- CR Outputs: Separate left and right control-room
(monitor) outputs with
balanced 1/4" TRS connectors. These can be used for control room speakers,
and are controlled by the monitor knob on the top panel.
- Pre-Insert Balanced Direct Outputs: Three DB25 connectors
divide the channels into groups of eight. You will need Balanced DB25
fan-out snakes (DB25-to-8 male XLRs or DB25-to-8 male 1/4" TRS) to connect
to these direct outputs. The outputs are post-gain, pre-insert, and pre-A/D
converter, and only the microphone preamps and line-level inputs are
available through the direct outputs.
- Subgroup Outputs: Balanced mono 1/4" outputs are
provided for each of the four subgroups. Subgroups allow you to combine
multiple channels into a single bus so the overall level for the entire
group is controlled by a single fader. The four subgroup outputs are
controlled by the four separate faders on the top panel, each with its own
- AUX Outputs: There are ten Auxiliary outputs, each with
balanced 1/4" TRS connectors. Aux mixes are routed to these outputs.
XMAX: The StudioLive's 24 XMAX preamplifiers are
custom-designed, high-voltage, discrete, Class A microphone preamplifiers
provide a wide dynamic range and extended frequency response. Their 30-volt
power rails (compared to the 10 to 18-volt rails found in most other
preamplifiers) provide more headroom, deeper lows, smoother highs, and delivers
a richer overall sound.
Phantom Power: The StudioLive provides 48V phantom power for
the microphone inputs on each channel. Phantom power is required for condenser
mics, and can be individually enabled for each channel using the 48V button in
the Fat Channel. It can be switched off for all channels where it is not
FireWire Ports: The Studio Live 24.4.2AI has two 40-in/26-out,
standard 9-pin FireWire s800 ports on the back panel. Either port can be used to
connect the mixer to your computer. The second port can be used to daisy-chain
additional StudioLive 24.4.2AI mixers, connect
devices (such as an external hard drive), or to daisy-chain an interface for
additional recording inputs.
Ethernet Port: A standard RJ45 jack is provided on the rear
panel for connecting the StudioLive mixer to LAN network. When you add a
wireless router, you can wirelessly control the unit from virtually anywhere,
using a laptop, iPad, iPhone, or iPod touch. This is especially helpful when you
need to use your remote device in a different room from the mixer.
S/PDIF Digital Output: The S/PDIF (coaxial) digital output
(female RCA) receives the same signal as the main outputs, however, any bus can
be routed to the S/PDIF output.
USB Port: The Type A USB port on the front panel is for use
with the included USB Wi-Fi module. This USB dongle helps you connect your
StudioLive AI-series mixer to a wireless network.
Fat Channel: The StudioLive 24.4.2AI's unique Fat Channel
transforms this compact mixer into the equivalent of a large console with over
100 signal processors. The Fat Channel lets you add dynamics processing and EQ
to every input and output, and even compare them with an "A/B" button. Each
channel and bus has its own compressor, limiter, gate/expander, and 4-band
parametric EQ. Each input channel, aux and FX bus has a high-pass filter, plus
you can invert the polarity of each input channel.
Select Display: The Fat Channel has a bright LED readout of the
selected channel, so you'll always know what you're working on: Input Channels
(channel number), Subgroup (S1-S4), Aux Outputs (A1-A9, AA), FX buses (A-D:
FA-FD), Auxiliary Inputs (RA and RB), and Main Bus (MA). The selected channel
also features a 16-ladder LED meter with Level and Gain Reduction indications.
Dynamics Processing and EQ: The main function of the Fat Channel is to
provide dynamics processing and filtering for every input and output. The
processing section consists of the following parts:
- Polarity Invert: 0° or 180°
- High Pass Filter: 24 Hz to 1 kHz (slope: -12dB/8va)
- Gate: with On/Off, Expander, and Key Listen buttons

- Low/Mid: 90 to 1.2k Hz
- High/Mid: 380 to 5k Hz
- High: 1.4k to 18k Hz
- Limiter: On/Off (ratio ∞:1)
Digital Effects: The StudioLive 16.4.2 has four programmable, 32-bit
DSP internal effects processors, marked A, B, C, and D. The processors for FX A
and FX B are dedicated to reverb and the built-in reverb library, while FX C and
FX D handle delay and the library of delay presets. The effects buses can be
routed to any of the subgroups, aux buses, or the main outputs. You can choose
from the following effects:
- Ambience: Natural, Lively
- Small Room: Closet, Studio A, Studio B, Bedroom
- Bright Room: Kitchen, Tile Floors, Tile Bathroom, Concrete
