    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. Only the consignee may institute a claim with the carrier, for damage incurred during shipping.

  • Page 3: The Front Panel

    Introduction Thank you for purchasing a LAB.GRUPPEN power amplifier. This manual contains important information on operating your amplifier correctly and safely. Please take some time and read this manual to familiarize yourself with the amplifier. The front panel Figure 1. Front panel...
  • Page 4 Cooling Your amplifier uses forced air cooling system to maintain a low and even operating temperature. All LAB.GRUPPEN amplifier, which ventilated, have front to rear cooling. There are several reasons for this, one is that there's usually...

    Figure 5. Rear panel connectors Do not use XLR and TRS jacks on the same channel simultaneously for mixing or other purposes. Figure 6. Balanced line To connect an unbalanced source, tie pin 3 (ring on TRS jack) down to the shield of the connector. If you leave one pin disconnected, you will lose 6 dB in gain.

    level attenuators are active, allowing you to set different levels for each channel. Never connect either output terminal to ground or in parallel. Bridged mono To bridge the amplifier, depress the Link switch (6) and Phase reverse switch (5). Both channels are then driven by a single signal at either input.

    Design features Cooling The LAB.GRUPPEN amplifier runs very cool due to a patented heat sink called Intercooler output devices (bi-polar) are mounted directly on a Indicators The two bottom green ”ON” LEDs indicate that the output circuits are receiving the correct rail voltage.

  • Page 9: Emc-Declaration

    When cool air hits the geometric fins of the Intercooler produced thereby enabling efficient cooling. Safety approvals LAB.GRUPPEN amplifiers are designed to meet the IEC65, a stringent electrical safety approval from the International Electro-technical Commission. The IEC65 is recognized world-wide with most countries having an equivalent.
