BGW Millennium Series 2TMC-2 (Discontinued)
Product Info & Specifications

The BGW Millennium Series Model 2 is available with a factory installed, internally mounted, TMC-2 Bi-Amp crossover/processor card.

This additional feature allows the user to fine tune the crossover points, equalization, attenuation and delay line all within the amplifier. The TMC-2 card is fully accessible above the input connectors on the rear of the amplifier and is protected by a metal security cover.

Modifications:

• Level Controls and LED indicators on the front panel read LF (Low Frequency) and HF (High Frequency) replacing Channel A and Channel B respectively
• Channel B input connector and bridge mono switch have been eliminated
• Output binding posts are labeled Low Frequency and High Frequency
• Signal/Chassis ground lift switch has been added
• A low frequency line level output can be installed in place of the 1/4" input-specify option

• Saves the cost of additional external crossovers and processing
• Frees up additional rack space
• Simplifies installation
• Reduces installation time
• Increased power

Level controls on the front panel normally should be set at maximum, the balance being set by the rear panel crossover level controls. Security "plug" cover for the attenuators can be installed to ensure tamper-proof volume settings.
