    9. Connect only to AC power outlets rated 200-240V, 50-60Hz. 10. Do not use this amplifier if the power cord is broken or frayed. Protect the power cord from being walked upon or pinched particularly at the plugs and the point where it exits from the apparatus.
  • Page 5 QKN= råé~ÅâáåÖ= Carefully open the shipping carton and check for any noticeable damage. Every Lab.gruppen amplifier is tested and inspected before leaving the factory and should arrive in perfect condition. If found to be damaged, notify the shipping company immediately.
  • Page 6 5. Clip/limit indicator This indicator signals if the amplifier output is clipping or limiting. It has two different indication states: If the clip limiter is engaged, it has a short time constant, and it illuminates briefly. If the clip limiter is not engaged, it has an increased time constant, and it illuminates for a longer period. (See page 15) 6.
  • Page 7 R= ob^o=m^kbi=cb^qrobp= Before turning the amplifier on please read the following sections to make sure that the unit is set up properly for your specific application. RKNKN= d~áå= The gain of the fP 2400 is fixed to 32 dB RKNKO= pÉåëáíáîáíó= Sensitivity is defined as how many volts (rms) or dBu (referred to 0.775Vrms) are required to get full output power.
  • Page 8 RKO= iáåâ=ëïáíÅÜ= The Link switches located on rear panel (switches between the four XLR input connectors) are for changing the operation mode of the amplifier. (See below, section 5.3). RKP= léÉê~íáçå=ãçÇÉë= RKPKN= píÉêÉç=ãçÇÉ= In this mode, both channels operate independently of each other.
  • Page 9 RKPKQ= _êáÇÖÉ=ãçåç=ãçÇÉ= Bridge mono mode is used to deliver two channels' power to a single load. The nominal impedance of the load must be more than 3 ohms. Set the Link switch to the pressed –“IN”-position and use one of the input connectors.
  • Page 10 3. If the loudspeaker is specified at a lower power handling, reduce the 4. Try the setup with a musical signal. If the amp runs into thermal If you reduce the amp’s output power by choosing lower MLS values, you only reduce the maximum output voltage.
  • Page 11 The amplifier uses a forced air cooling system to maintain a low and even operating temperature. All fan-cooled Lab.gruppen amplifiers have front to rear airflow. There are several reasons for this, one being that there is usually cooler air outside the rack than inside, and therefore the amplifiers can run at higher continuous power levels without thermal problems.
  • Page 12 The warranty will not cover damage caused by connecting to the wrong type of AC mains. Lab.gruppen switch mode amplifiers use primary switching. The mains power is being rectified directly in front of the transformer, meaning that the power supply is insensitive to the mains frequency and will operate from DC to 400 Hz.
  • Page 13 Last, the "regular operating power" as defined by the safety standard IEC 65/ANSI/UL 6500 and used by a majority of safety agencies. The regular operating power is measured by using pink noise, and with an average output power equal to 1/8 of full power. The one eighth of the total power is as loud as you can play music while making some attempt to avoid obvious clipping.

    Channel A and B (or C and D) into one Speakon. . (Quad or Bi-amp) Never connect either output terminal to ground or to some other output or input terminal. For normal four-channel operation, connect each speaker load across the output’s positive and negative terminals.

    V= molqb`qflk=cb^qrobp= Each Lab.gruppen amplifier has many advanced protection features. Should a fault condition arise they are protecting both, the amplifier and the speakers connected to it. Under normal use these features are inaudible. All protection circuits work independent from each other.

  • Page 17: Operating Voltage

    VHF protection will re-initiate. VKNKQ= pÜçêí=ÅáêÅìáí=éêçíÉÅíáçå= All Lab.gruppen amplifiers are completely short circuit protected. The protection circuitry permits very high peak currents, but still holds the output devices within the safe operation levels. If a short circuit remains to be present, the channel effected will eventually go into thermal protect cycle until the short circuit has been removed.
  • Page 18 In the unlikely event of on a non-user rectifiable fault, return the amplifier to your supplier or an approved service centre. Lab.gruppen cannot be held responsible for damage or injury as a result of the top or bottom cover being removed.
