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...
3 introduction thank you for purchasing a lab.Gruppen power amplifier. The amplifier you have chosen is the culmination of many years of research and development. This amplifier makes amplification more controllable instead of the traditional "boring black box" you have become accustomed to. Please ...
Please refer to diagram on page 3 1. Speaker connector this type of speaker connector may be unfamiliar to some users. A full description is found in the operation section. (see page 6). 2. Minimum load selector (mls™) switches these switches are used to select the minimum nominal speaker impedance ...
5 4. Grounding there is no ground lift switch or terminal on this amplifier. The signal ground is always floating via a resistor to chassis and the grounding system is automatic. If a potential above 0.6v presents itself between signal ground and chassis ground, a short circuit is introduced between...
There are also trs jacks for linking etc. They are wired as follows: tip hot ring cold sleeve shield/ground 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...
8. Impedance matching (mls-switches) the mls switches is located on the rear panel. The mls ( minimum load select ) switches offer a impedance matching, so you can drive the lab 2002 in 2 ohms without increased heat losses. As stated earlier the lab 2002can produce at least 1100 watts into any imped...
8 to obtain an output, connect the speaker leads to pin +1 on channel a speakon to speaker positive terminal and pin +1 on channel b speakon to speaker negative terminal . Do not connect either of the -1 (negative) pins of the speakons. Do not connect speakers to channel a or b in the normal manner ...
9 figure 13. Front indicators 5. Indicators the two bottom green ”on” leds indicate that the output circuits are receiving the correct rail voltage. The ”-25 db” leds glow when the output signal is greater than -25db, 0db is referenced to full output power. These leds also act as signal present indi...
Design features cooling the lab.Gruppen amplifier runs very cool due to a patented heat sink called intercooler tm . The output devices (bi-polar) are mounted directly on a copper heat sink thereby avoiding thermal losses normally found when using mica washers (the heat sink is mounted horizontally ...
Safety approvals lab.Gruppen amplifiers are designed to meet the iec65 (now called en 60 065), a stringent electrical safety approval from the international electro- technical commission. The iec65 is recognized world-wide with most countries having an equivalent. Emc approvals emc stands for electr...
Appendix a mains voltage selection lab 2002 is normally shipped for 230 volt ac operation only. For export there is a 115/230 volt ac option available. To check if the amplifier is equipped with this option, please follow these steps: 1. Make sure that the lab 2002 is unplugged from the mains voltag...
Warranty and disclaimers • general this product is manufactured by lab.Gruppen and is warranted to be free from defects in components and factory workmanship under normal use and service, for a period of one year from the date of original purchase. During the warranty period, lab.Gruppen or its nomi...
