- Seite 7 Lexicon NT Series Amplifiers Overview Models 212 and 225 The 212 stereo amplifier consists of 2 amplifier modules, each with its own power supply. The channels may be operated independently (1=left; 2=right) for stereo at 120 watts/channel @ 8Ω, 200 watts @ 4Ω, or bridged (monaural) to form a single 400 watt amplifier into 8Ω.
- Seite 8 Lexicon NT Series Amplifiers Model 412 The 412 power amplifier consists of 4 independent amplifier modules, each with its own +55V power supply, and 4 custom power transistors for a total of 16 output devices. The 412 can be configured to drive 2, 3 or 4 speakers: 4 channels at 120 watts into 8Ω, or 2 channels at 120 watts plus 1 channel at 400 watts, or 2...
- Seite 9 Lexicon NT Series Amplifiers Installation Selecting the appropriate installation location for your amplifier is perhaps the single most important factor in ensuring a long trouble-free service life. Al- though the amplifier is very conservatively designed, you must provide some airflow around the unit. If you intend to stack multiple amplifiers in an enclosed space, you should consider installing a fan or otherwise assuring adequate airflow around the amps, as they rely on convection cooling.
- Seite 10 Lexicon NT Series Amplifiers Lexicon amplifiers do not require any specialized line conditioners, as they have Power special power supply circuitry designed to reject power line problems like line Requirements spikes, surges and RFI. Simply plug each amplifier directly into a line socket. In areas where there is a high likelihood of lightning strikes or other potentially catastrophic surges, additional protection may be warranted.
- Seite 11 Lexicon NT Series Amplifiers Operation Front Panel LEDs All amplifiers in the Lexicon NT Series are equipped with sophisticated com- parator circuits which detect sources of signal distortion including clipping, excessive DC or supersonic signals, and short circuits in the cabling. Multi- function LEDs on the front panel are provided to alert you to various opera- tional states of the amplifier.

Please refer to the rear panel diagram for each model for specific wiring information. Note that only the red colored output connectors are used in bridged operation.
