Unpacking 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... -

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... - Page 5 AC line cord.

Figure 4. TRS phone plug The input impedance is high enough (20 kohms balanced) to allow ”daisy-chaining”, or multiple parallel input connections. To daisy chain, use the TRS jacks provided on each channel. The input circuits also have a high enough headroom, to accept the maximum output level from virtually any low level signal source. -
Page 7: Operation
Never connect either output terminal to ground or in parallel. The recommended minimum nominal impedance, for stereo or tandem operation, is 2 ohms per channel. Tandem mono For tandem ( dual channel-single input) operation , depress the Link switch. Both channels can now be driven by a signal, at either input connector. -
