Speaker Bridging
Associated channel pairs (Ch 1&2 or Ch 3&4) of your Tube Driver
BLUE are capable of being bridged into 2 separate 4-Ohm
(minimum) speaker loads without switches or bridging modules.
You can achieve these mono channels by using the Ch 1 negative
(-) speaker connection and the Ch 2 positive (+) speaker
connection for the first channel. Then use the Ch 3 negative (-)
speaker connection and the Ch 4 positive (+) speaker connection
for the second channel .
By not operating your Tube Driver BLUE at less than the minimum
recommended speaker impedances will produce better sound and
natural musical dynamics.
Important Note: Bridged impedances of less than 4 Ohms may
trigger protection circuitry engagement and may eventually
damage your amplifier.
Typical Applications
There are 2 basic configurations most often used with a 4 channel
amplifier:
1) Use Ch 1 and 2 bridged mono into a sub-woofer system of
minimum of 4 ohms. Channels 3 And 4 are then used as
stereo channels for the mid and high speakers/tweeters by
the use of passive crossovers
2) Use a 3-way electronic crossover to send the mid
frequency stereo signals to the RCA inputs of Ch 1 and 2.
Ch 3 & 4 are used for the high frequency signals. A
separate amplifier is needed (such as Tube Driver BLUE
2150) to drive the bass/sub woofer system.
