More data about FM Accoustics:

The FM Acoustics FM-216 is a precision Line Level Interface unit manufactured by the Swiss high-end audio company, FM Acoustics. It is specifically designed to solve common signal-matching problems between different audio components in both professional and domestic environments.
Key Functionality
The primary purpose of the FM-216 is to act as a precision step-down/un-balancing interface. It is engineered to take a balanced signal and convert it into a high-quality single-ended (unbalanced) signal.
* Application: It is frequently used when a balanced preamplifier output needs to be connected to equipment with unbalanced inputs (such as subwoofers with -10dB inputs).
* Performance: FM Acoustics emphasizes that the unit is "totally transparent," meaning it aims to pass the signal through without adding coloration, compression, or distortion.
* Adjustability: While it typically features a fixed attenuation of 14dB, it can be internally adjusted to any level between 7dB and 60dB for specialized applications.
Technical Characteristics
* High Headroom: It is designed to handle very high signal levels, with a maximum output capability of +28dBv (50Vpp).
* Driving Capability: The unit is built to drive difficult impedances and long cable runs without the signal degradation often found in standard line buffers or interface units.
* Noise Management: It is designed to operate with extremely low levels of hum and noise.
* Complementary Unit: It is often discussed alongside the FM-214, which provides the inverse function (a precision balanced line driver).

The converter has only had one owner and was used in a few sound projects in Stockholm in the 1990s.

NOTE: An external AC converter of +30 Volts is not included. It has been lost.

In addition to a new and better connection connector for the power supply, there is a newly mounted LED on the front with a connection cord.

However, it is not connected.

The converter is complete and works perfectly but a new AC converter of 30 Volts needs to be purchased.

A loose cable is included. A bag with a loose connector is also included.

Connection instructions are included.
The converter is rare on the internet today and the quality is excellent.

However, there are some light small marks on the top.

The serial number is inside the unit.
