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.

The new AT8657/LED table-mount microphone adapter adds functionality to quick-mount gooseneck models from the Audio-Technicaʼs Engineered Sound, Unipoint and ProPoint installation mic ranges and ES945 and ES947 boundary microphone models.
The new AT8657/LED features a touch-sensitive capacitive switch surrounded by an illuminated LED status ring that can be set between red (mute) and green (on). Its integrated 3-pin XLR allows the table-mounting of gooseneck microphones with XLR connectors while the AT8657/LED has a 5-pin XLR out for audio and control data.

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
