Shure PM4E 6in-6out 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.
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 Shure's 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.

The AKG C 480 B preamplifier powering unit is the latest model in the ULS series. It accommodates the CK 61/ULS, CK 62/ULS, CK 63/ULS capsules and the new CK 69/ULS shotgun capsule, providing a higher order of performance for these capsules than previously available.
The new preamp has a vastly improved noise floor, permitting self noise performance with the four associated capsules in the range of 9 to 11 dB-A. Maximum sound pressure levels in the range of 144 dB (in the -10 dB sensitivity position) can be attained with no greater than 0.5% distortion, giving the capsules a new level of overall performance. An integral low cut filter (12 dB/octave) can be set for either 150 or 70 Hz. The +6 dB sensitivity position is intended to enhance the performance of the CK 69/ULS interference tube capsules, which normally operate over large distances.
With the available CK 61/ULS cardioid, CK 63/ULS hypercardioid, CK 62/ULS omnidirectional, and highly directional CK 69/ULS shotgun element, the C 480 Series is intended primarily for studio, broadcast and a variety of live sound and speech reinforcement applications in which state-of-the-art performance is required. A complete line of optional accessories is available. The C 480 B operates only on 48 volts phantom powering. Check the Related Products.
Features:
- Ultralow noise preamplifier for use with ULS series capsules
- Multiple directional capsules and configurations available on a high performance powering/preamp module
- Extremely flat on-axis response for all models
- Three sensitivity settings (0, +6, and -10 dB)
- High acoustic level capability
Specifications:
- Polar pattern: 10 to 30,000 Hz
- Preattenuation pad: +6, 0, -10 dB, selectable
-
- Bass filter: 12 dB/octave at 70 or 150 Hz
- Impedance: 2000 ohms/1000 pF
- Supply voltage: 48 V phantom power to DIN 45596

B23 L Battery-operated phantom power supply & mini recording mixer
The B23 L is a compact power supply unit that provides 9V phantom power to the AKG MicroMic series. Two mini-XLR-F inputs (L and R) ensure optimum use for up to two microphones. Both inputs of the B23 L can be switched either to mono or stereo mode. The output is a standard 3.5mm stereo jack. Two AA batteries guarantee an average use of 30 hours.
Another great feature of the B23 L is that it can be used as a small and portable mixer. Two separate volume controls allow the user to set the level of each microphone independently. Customers who want to compensate level differences between two audio sources (e.g. voice and instrument) will greatly benefit from this feature. On the rear panel of the B23 L there is the battery compartment and a metal clip for fixing the B23 L to a belt, guitar strap or the like.
The B23 L is an attractive solution for customers who are looking for a small and portable power supply capable of mixing up to two audio signals in one device.
