Peavey IA 400V, IA 800V, IA 200V, IA Series Stereo Mode Connection Diagram Parallel Mode Diagram

Bridged mode converts the amplifier into a single-channel unit with a power rating equal to the sum of both channels’ power ratings, and at a load rating of 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 con- necting the negative (-) terminal of input A to the positive (+) terminal of Input B. Both channel atten- uators (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 IA 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 Load Fault Correction circuit and may also cause a thermal protect condition. NOTE: Regardless of operating mode, NEVER connect amplifier outputs together!

LINE CORD (120V Products Only)

For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adapters should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with the proper grounded receptacles.
