Alesis 12R manual Monitoring AUX 1 in the Phones jack

Applications

Monitoring AUX 1 in the PHONES jack

If you are using AUX 1 as a monitor feed, you may want to check that mix using the headphones. If you've connected the PA or recorder to the MAIN OUTPUTS, and are not using the TAPE IN jacks, use Y-cords to connect the AUX 1 SEND to the TAPE IN jack(s) at the same time it feeds the monitor amplifier. Use the front panel [PHONES/MONITOR] switch to select between the main and aux 1 feeds.
