Cinénova Grande Power Amplifiers
Bridging Channels: Understanding the
The Cinénova Grande BR is capable of bridging its channels in order to
produce even more power. Bridging is achieved by setting two channels
out of phase. This leads to a differential voltage between two blocks. In
bridge mode, you are required to set one channel to master (non-
inverted) and the second to slave (inverted). Since power is V2/R, the
bridged output blocks will produce two times more than the unbridged.
Please check your speakers' power handling capability as
bridging could overload your speakers.
In bridge mode, connect the positive terminal of the master channel to
the speaker positive and connect the positive terminal of the slave
channel to the speaker negative. Be sure to connect the negative
terminals of both bridged channels with the jumper wire.
Advantage
Two bridged channels will more than double the wattage output of one
channel. This will maximize the amount of power that this amplifier is
capable of. For example:
1 channel outputs 300WRMS at 8 ohm
2 bridged channels output 1000WRMS at 8 ohm
MARS Technology
Cinénova Grande BR implements MARS technology (Magnetically
Actuated Reanimation System). This is a new type of protection system
that enables the use of all the amplifier's power resources without
compromising the survivability of the amplifier under catastrophic
conditions. MARS is different as it is not in the signal path, but works by
sensing the electro-magnetic signature of the speaker output wire then
translating this input into amperes flowing through the wire.
During testing, the MARS technology showed that the output of the
amplifier could be short-circuited at full power more than a thousand
times with no damage to the amplifier. A specially designed circuit
instantly shuts off the output drive.
In the event a short-circuit activates the MARS protection system, it
continuously re-scans the output every 10 seconds. Normal operation
automatically resumes as soon as the short-circuit condition is
removed.
