EIAJ ratings are short term burst ratings, but are representative of mid/high signals with a typical crest factor for common music. We have tested these amplifiers at 100Hz into 2 ohms and 4 ohms for purposes of assessing bass response. Continuous signals into low impedances trigger current limiting in the amplifier (self protection) which reduces the output power. Higher crest factor signals are limited by voltage rather than current, which allow higher burst powers into 2 ohms.

From 2023 the Q3 also has a bridge mode available, which can be activated using the switch on the back. In Bridge mode each pair of channel (A B) and (C D) are bridged to make a high power channel. For ChA B , to wire your speakers in bridge mode, you connect your speaker between the positive output of channel A (1 on speakon A) and the positive output of Channel B (1 on speakon B or 2 on speakon A). Your speaker is connected between the outputs on both channels, and the signal is amplified such that when channel A runs a positive voltage, channel B runs a negative voltage, so the voltage from peak to peak is doubled.

In bridge mode the power outputs are:
2 ohm: 1700W * EIAJ burst ( 2 ohm operation is recommended for short term use in applications with high crest factor)
4 ohm: 1400W * EIAJ burst
8 ohm: 800W * EIAJ burst
