SHURE P4M Four Channel Personal Monitor Mixer
The P4M is a highly versatile four-channel, two-bus stereo mic/line mixer designed to optimize use of personal (in-ear) monitors like the Shure PSM 400 in live performance. The P4M features four balanced mic/line inputs, each with level and panning controls. Corresponding XLR split outputs allow input signals to pass through the unit unaffected, while providing an independent mix.
When coupled with personal monitors, the P4M allows performers the ability to adjust personal mix levels onstage - even during a performance - without affecting the front-of-house system. This enables users to create and maintain consistent monitor mixes, regardless of what the venue can provide for monitors.
The P4M can also be used as a small "piggyback" mixer in applications such as houses of worship, or courtrooms. The unit acts as a console bypass when a permanent installation of a large, operator-controlled mixing console may require just a few microphones for smaller events. This allows the user easy access and control of up to four signals without having to utilize the larger console.
The P4M has a pair of 1/4-inch auxiliary inputs that can be used to add channels from other sources. For example, multiple P4M mixers can be linked together to increase the number of inputs. In addition, sources not present in the original mix - such as a click track for live percussion - may be included via the auxiliary inputs.
