Are Tube Driver BLUE home amplifiers bridgeable?
Top of Page A: The TDB 2250 is designed to operate in either stereo or bridged mode. It has a Mono/Stereo selector switch on the back panel and a seperate connector specifically for mono/bridged operation. To operate the TDB 2250 in bridged mode, you connect a single RCA to the Channel 1 RCA jack, set the Stereo/Mono switch to Mono (down) and then connect the speaker wire to the mono binding post connector (the center one). Minimum speaker impedance in Mono mode is 6-8 Ohms. DO NOT attempt to bridge either the TDB 3150 or the TDB 5150 amplifiers as this creates a short and will cause the amplifier to shut down.
