Sonodore battery powered Power Supply PSB-402LI for: RCM-402, CCM-65, BLM-21, LDM-54 and CMA-16.

As part of the initial Sonodore philosophy, all microphone models, except the RCM-402/48V,
are 'active' powered via a separate power supply (PS-402), instead of using
standard phantom power. Phantom-fed microphones are inherently less suitable
for high-quality audio usage since they work as compressors: when, for instance, high
dynamics are required, strong demands are made on the current supply of the phantom.
As a result, the current supply drops drastically and the stereo image and frequency
response collapse with it. To avoid this, the RCM-402 is available in a version with a
separate power supply which allows a high-grade and exceptionally low-distortion
amplifier to be placed directly in the microphone body.
With active powering, the supply current of the microphones flows through a separated wire.
 

Batteries and sound quality of components

It is a well known and documented fact, that battery powered audio equipment 
(separated from the main voltage) sounds substantially better.
There are several plausible reasons for this. Apart from getting rid of the pollution on the
main power, also the absence of interfering ground currents adds to the improvement also. 
The sonic improvements due to battery powering are: 

• more softness in the high frequencies
• more robustness in the low frequencies
• a much more relaxed projection of the sound images
• less noise artifacts
• faster reaction time
• an overall much more realistic and pleasant sound
  

To achieve a higher sound quality than the PS-402, the microphone powering is available
with a battery power: PSB-402. 
 

The PSB-402LI is available in 2 versions:
1) Input 6 pin XLR  (+16V -16V and capsule voltage)
Intended for customers who has microphones with 6 pin XLR.

2) Input 4 pin XLR (+60V).
Intended for customers who has microphones with a mains power supply and a 4 pin XLR.
