SIGNAL MODE CONFIGURATION
ICA™ Series amplifiers are configured for Stereo (2-channel), Bridged Mode, or Parallel Mode operation at the input connector.
To send the same signal to both channels (Parallel Mode), connect the input signal to CHANNEL A via the input connector. Run jumpers from the positive and negative terminals of the CHANNEL A input connector to the respective terminals of CHANNEL B. Both channels then share the CHANNEL A input signal but will operate independently. Speakers are connected as in Stereo Mode.
Bridged Mode converts the amplifier into a single-channel unit with a power rating equal to the sum of both channel power ratings, and at a load rating twice that of the single-channel rating. In Bridged Mode, the channels operate at opposite polarity of each other so that one channel “pushes” and the other “pulls” equally. Signal is connected to the input connector with one jumper connecting the positive (+) terminal of Input A to the negative (-) terminal of Input B, and another jumper connecting the negative (-) terminal of Input A to the positive (+) terminal of Input B. Both channel attenuators (A & B) are used to control signal level, and both must be at the same level, preferably at 0 dB attenuation. The speakers are connected only to the designated “+” output terminals. NEVER ground either side of the speaker cable when the amplifier is in Bridged Mode as both sides are “hot”. If an output patch panel is used, all connections must be isolated from each other and from the panel. For ICA Series amplifiers, the minimum nominal load impedance in Bridged Mode is 8 ohms; this is the equivalent of driving both channels at 4 ohms. Driving loads of less than 8 ohms may activate the LFC circuit and may also cause a thermal protect condition. NOTE: Regardless of operating mode, NEVER connect amplifier outputs together!
