P4M Four
Channel Personal Monitor Mixer |
|
Product Code: p4m
|
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. |

Personal Stereo Monitors
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 is
available individually for use with Shure PSM 600 and PSM 700
Personal Monitor Systems; or packaged with the PSM 400 Hardwired
and Wireless Performance Packs.
Installed Sound Systems
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. Given its dual-bus output capabilities, the P4M can
also serve as a "two zone" mixer, routing any combination of mic or
line-level signals to two different zones.
More Than Four Inputs
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. |
