Touring and Installation Amplifiers
Quick Start Guide
Lab.gruppen IPD Series amplifiers provide exceptionally high power density and powerful integrated DSP features, making them suitable for a
broad range of installed and touring sound applications. All IPD Series amplifiers feature both analog and AES3 inputs with link outputs; input
mixing; comprehensive DSP functions (crossover, parametric EQ, delay and limiter control); network control via Ethernet on Cat-5 cable or using
suitable WiFi access point; IntelliDrive™ Controller software and iPad native app; comprehensive front-panel display and dedicated mute buttons;
and both binding post and Neutrik speakON output connectors.
The information contained in this Quick Start Guide is sufficient for proper installation of IPD Series amplifiers, and for configuration of settings
in typical applications. Please refer to the full Operation Manual for detailed information on maintenance, cooling requirements, warranty, and
configuration for complex installations.
Except as specifically noted, all features, values and connections are identical for the IPD 1200 and IPD 2400.
Important safety instructions

Please ensure that there is sufficient space in the front and the rear of
each amplifier to allow for a free flow of air. No doors or covers should
be mounted either in the front or rear the amplifiers. Amplifiers may be
stacked directly on top of each other with no spacing, though some
spacing may enable more convenient installation of rear cabling.

que des vases ne doit pas être placé sur l’appareil.
Refer to the full Operation Manual for thermal dissipation value when
installing large numbers of amplifiers in air conditioned spaces.
Operating voltage
This apparatus must be connected to a mains socket outlet with a
protective earthing connection.
Français: Cet appareil doi t être raccordé á une prise de courant
qui est branchée à la terre.
The mains plug is used as a disconnect device and shall remain
readily operable.
Français: Lorsque la prise du réseau d’alimentation est utilisés comme

All IPD Series amplifiers have a universal power supply that operates
on mains from 100 – 240 V at 50 or 60 Hz. The IEC receptacle on
the rear panel accepts the supplied IEC cord which terminates in a
connector appropriate for the country of sale. When AC power is
connected, the amplifier goes into standby (red indication on standby
LED). The amplifier may be turned on by pressing the front power
button or remotely using the IntelliDrive Controller software.
Unpacking and visual checks
Signal ground is floating via a resistor to chassis, and therefore
grounding is automatic. For safety reasons, never disconnect the earth
(ground) pin on the AC power cord. Use balanced input connections
to avoid hum and interference.
Every Lab.gruppen amplifier is carefully tested and inspected before
leaving the factory and should arrive in perfect condition. If any
damage is discovered, please notify the shipping carrier immediately.
Save the packing materials for the carrier’s inspection and for any
future shipping.
IPD 1200 – Depth is 272 mm (10.7 in) rack ear to back panel. Weight is
approximately 4.6 kg (10.1 lbs). Use of rear support brackets (optional)
is not necessary for fixed installations but should be considered for
very demanding touring applications.
IPD 2400 – Depth is 360 mm (14.2 in) rack ear to back panel. Weight
is approximately 6.2 kg (13.7 lbs). Rear support brackets are included
and use is recommended in all applications.

Front panel
7 ADJUST/SET (Rotary Encoder) – Rotation moves through the menu
and adjusts the currently selected parameter when in setup mode.
Pressing down on the knob selects a given parameter or advances
further into the menu.
The following indicators and controls are available on the front panel:
1 MENU – Selects MENU mode and confirms a given preset name.
2 BACK – Moves backward through menu layers in MENU mode.
In operating mode, rotation of the ADJUST/SET encoder adjusts
output gain (outputs ganged).
3 MUTE – Mutes corresponding channel as indicated.
4 SIG – Illuminates green when signal is present. Illuminates red when
signal is clipping (pre input mixer)
In operating mode, the display shows the following values and status
5 POWER – Indicates STANDBY (red)
6 LIM (limit) – Illuminates when the amplifier limits the signal.
Limiting is engaged when the channel:
• Reaches the selected voltage limit
• Rail voltage sags below the selected threshold (both LEDs flash
rapidly for 1.5 sec)
• Maximum current output reached
• Mains voltage cannot maintain full rail voltage
• Level – Horizontal VU meters for each channel
• Device name and Preset name
In setup mode, the display shows currently selected menu locations
and parameters. For more information on DSP setup procedures,
please refer to the Operation Manual.
Rear panel
The following connectors are available on the rear panel:
4 speakON OUTPUT CONNECTORS – Both channel outputs are
available on a four-pole connector at the left; either channel 1 or both
channels 1 and 2 may be connected. Only channel 2 is available on
the connector to the right.
1 ANALOG INPUTS and LINK - XLR-F input connectors provided for
each channel, with XLR-M link output connectors.
2 AES3 INPUT and LINK – AES3 digital inputs are on an XLR-F
connector with a link output on an XLR-M connector.
5 BINDING POST CONNECTORS – Connectors for channel 1 and
channel 2.
3 NETWORK (Ethernet) – An RJ45 jack is supplied for connection
to an Ethernet network for external control and monitoring, either by
a direct wired connection or via an external WiFi router to an iPad or
tablet. LEDs below the connector indicate valid network connection
(LINK) and network activity (ACT).
6 AC LINE INPUT – A locking IEC receptacle accepts the AC line
input, 50 Hz or 60 Hz, 100 V – 240 V. Use an IEC cable with the proper
connector for country of use.
Input connections
Output connections
Two types of power output connections are available on IPD
Series amplifiers: Neutrik speakON and binding post. The
two types are connected in parallel. Loudspeakers may be
connected to both at the same time, but this is generally not
recommended as total impedance may be too low.
Analog Inputs
Analog inputs are available on two standard XLR-F latching connectors.
The inputs are electronically balanced. The impedance is 20 kohms, and
the inputs can accept a maximum input level of +26 dBu.
Polarity is as follows:
Pin 1 = screen (shield), pin 2 = positive (+), pin 3 = negative (-).
Binding Posts
Power outputs for loudspeaker connection are available on two fully
enclosed binding posts. Observe signal polarity as indicated.
Analog Links
Two latching XLR-M connectors are adjacent to the analog input
connectors and are paralleled to the input connectors to provide an
unprocessed analog loop-through to feed additional IPD Series units
or other equipment.
speakON Connectors
Outputs for both channel 1 and channel 2 are available on a four-pole
speakON connector to the left. The two-pole speakON to the right
connect to output 2 only. See diagram for output connection and
*see fig 1
AES3 Inputs
A latching XLR-F connector accepts an AES3 digital audio signal. Input
impedance is 110 ohms. (Ensure that 110 ohm digital audio cables are
used; standard XLR microphone cables are rarely suitable for reliable
digital audio transmission.)
NOTE! When connecting wiring to Speaker Terminals, the installation
shall be made by an instructed person or ready-made leads or cords
shall be used
Bridge Mode
The IPD Series employs an inherently bridged Class D output topology;
Under no circumstances should the IPD Amplifier be bridged, this may
cause undesired operating performance.
AES3 is a stereo digital format, and therefore both inputs are fed via a
single connector. Selection of the analog or digital inputs is made via
the front panel display or IntelliDrive Controller software.
AES3 Link
A latching XLR-M connector is fitted adjacent to the AES3 input
connector. This is an active link which sends an unprocessed
AES3 loop-thru to feed additional IPD units. The design requires no
termination load when the unit is the last connected.

DSP configuration
Default configuration
IPD Series amplifiers are shipped with default DSP settings that allow
immediate use in many common applications with no need for further
DSP configuration. The default mode is suited for use with the stereo
program into full range loudspeakers. The main signal routing and
parameter settings are as follows:
