    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.

    the amplifiers. There are eight positions with different gain, from 20dB to 41dB in 3dB steps. See the different settings for the DIP-switches in the table below. The three switches to the very left are for channel B, and the three to the very right are for channel A.

  • Page 8: Tandem Mode

    Reverse operation of Channel B. RKPKP= q~åÇÉã=ãçÇÉ= In tandem mode both channels' inputs are linked and receive the same signal. The tandem mode is active if the Link switches are in position "On". Both level attenuators are active, allowing you to set different levels for each channel.

  • Page 9: Installation

    S= fkpq^ii^qflk= SKN= jçìåíáåÖ= The amplifier is one rack unit high (1U) and will mount in a standard EIA 19” rack. Amplifiers may be stacked directly on top of each other. If the average power is above 1/8 of full power, spaces between units and/ or forced air cooling may be used.

  • Page 10: Power Consumption

    SKR= mçïÉê=Åçåëìãéíáçå= There are three ways to determine the power/current consumption of the amplifier: First, the peak current draw at full output power. Under this condition the power will blow the mains breaker within 30 seconds, or the amplifier will operate for less than 2 minutes before thermally limiting.

  • Page 12: Unbalanced Inputs

    They are wired in the following manner: The right jack, Channel A, has both channel A and B outputs, so it’s useful for bridging and bi-amp operation (see bridged mono operation on page 7). Channel B, carries only the channel B output.

  • Page 13: Operating Voltage

    U= lmbo^qflk= UKN= léÉê~íáçå=éêÉÅ~ìíáçåë= • Make sure that the power switch is set to “off” before connecting any input or output or operating the switches on rear panel. See pages • Make sure that the AC mains voltage is correct and the same as the one printed on the rear panel of the amplifier.

  • Page 14: Protection Features

    Apart from this single exception, Lab.gruppen recommend to leave the clip limiters switched "on" (button depressed). As a side-effect, once the amplifier comes out of a protect condition, the output level has a slow rise time –...
