ONLY switch modes when the amplifier’s power switch is OFF!
This feature is intended to be used where the load is known.

The AP2020 is not only suitable for use in both heavy duty touring sound reinforcement systems but also when high head- room and low distortion are needed to fully reproduce the dynamic range and clarity of today’s CD recordings. It is built to survive grueling road conditions and constant

WARNING: When driven to full power in Bridge Mode here is more than 70 Vrms appearing between the binding posts. This represents a significant shock hazard and due care should be taken when making any speaker connections. Ensure that no strands of bare conductor are exposed after inserting the speaker wire into the hole in the side of the binding post terminals.

Power Output
All values are in WATTS. Measurements were made at the 0.1% distortion point. Some CONTINUOUS AVERAGE POWER measurements required line currents greater than 15 Amps. The amplifier under test was plugged into an IDEAL POWER LINE consisting of a REGULATED 120 VAC RMS 60 Hz pure sine wave. Ordinary AC “wall outlet” lines will always exhibit varying and unpredictable amounts of sag. To produce objectively verifiable and accurate specifi- cations these unknown factors must be eliminated by using an ideal AC line. When using an ordinary electrical outlet, it will usually be possible to get 2400 Watts when the AP2020 is bridged into 4 ohms. The BURST measurements use
a 10mS burst at 1KHz with a 1/8 second pause between bursts. The 1KHz burst represents the maximum possible sine wave output power.
