G_2Systems M.P.A.1 VPR Microphone Preamplifier API500

This is the G_2Systems Ultra-Fast, High-Resolution API500 Chassis Compatible Microphone Preamplifier M.P.A.1 VPR.

I am selling this item due to equipment consolidation.

This unit is a model with the same circuit design as the SymProceed SP-MP500, known for its uncolored, ultra-fast, and ultra-clean, original sound-focused microphone preamplifier. Its sound quality is evaluated in the field as being virtually identical, making it suitable for those who demand thoroughly pure amplification.

■ Specifics unique to this unit (*Please read carefully*)
As a characteristic behavior of the M.P.A.1 VPR, there is a specification where **when the PAD and Low Cut are used simultaneously, the low frequencies are extremely cut, as if a high-pass filter has been applied.**
When I purchased it, the store salesperson informed me that these cannot be used simultaneously. I have confirmed this behavior during a pre-sale operational check using an analyzer, which showed a similar result (Low Cut alone gently attenuates from around 50Hz, but extreme low-frequency attenuation occurs when used with PAD).
This is not a malfunction but a unique circuit specification of this model. It is unlikely you would use them simultaneously, but please be aware.

■ Operational Check and Condition
Basic operations (phantom power, gain control, standalone Low Cut and PAD) have been confirmed to function correctly in my environment.

[External Condition]
There are small scratches on the back of the circuit board. However, as it was used without being removed from the chassis, it is generally in clean condition. Please check the photos carefully.

[Accessories]
None. Main unit only.

*An API500 series compatible power rack is required for use.

The current new price for this model is around 100,000 yen. If you have been looking for this item, please consider this opportunity.

Feel free to request additional photos or ask any questions.
