5. Amplifier installation
5.1. Unpacking and visual check
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.
5.2. Rack installation
IPD 1200 - Depth is 272 mm (10.7”) rack ear to back panel. Weight is approximately 4.6 kg (10.1 lbs). Rear support brackets are included and use is recommended in all applications.
IPD 2400 - Depth is 360 mm (14.2”) 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.
5.3. Cooling requirements
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 of 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. Refer to the Thermal Dissipation charts in Section 15.2 for thermal dissipation values when installing large numbers of amplifiers in enclosed spaces.

6. Amplifier connections
6. Amplifier connections
6.1. AC line input / operating voltage
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 plug 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.
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.
6.2. Audio inputs
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 (-).
Analog links - Two latching XLR-M connectors are fitted adjacent to the analog input connectors and are paralleled to the respective input connectors; they provide an unprocessed analog loop-through signal to feed additional IPD Series units or other equipment.
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: 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.
