guarantees that unbalanced signals from consumer, video, semi-pro and pro equipment remain pristine when interfaced with true balanced equipment operating at levels of +4dBv, +6dBv, at the
nominal broadcast level of +8dBv or any other high level - this with absolutely unparalleled performance. With its superior headroom and the capability of delivering a maximum output of +28dBv
(50Vpp), the 2-channel FM 214 and FM 216 exceed the most exacting standards of state-of-the-art recording and reproduction systems. Due to their capability of driving very difficult impedances
and long cables without the headroom and drive limitation of the usual interface units and line buffers, the FM 214 and FM 216 instantly solve line drive and interface problems in critical
By substituting these units for existing interface units, or by adding the FM 214 at the output of equipment with the usual mediocre output drive-circuits, an astounding performance improvement can be realized.
High quality domestic systems can be lifted to a superior balanced configuration.
The FM 216 complements the FM 214 in applications where a true precision step-down/un-balancing interface is required (for special applications its fixed attenuation of 14dB can internally be adjusted to any other level between 7dB and 60dB).
The FM 214 and FM 216 are the ultimate interface units, capable of resolving any level and/or impedance problem that arise between any kind of audio equipment.
These two units provide a breakthrough in accuracy of reproduction, being the only interface units available which guarantee no signal degradation and absolute transparency. These results have been verified under the most demanding of conditions in numerous state-of-the-art recording, mastering and broadcast facilities around the world.
which frequently is not given adequate attention is how the unit will perform with real world loads and real world cables connected to the output (sometimes hundreds of meters!). Within a given
electronic circuit performance is quite predictable, as the input impedance of the next stage is clearly defined and the driving stage can then be optimized for this fixed and non-varying load
impedance. An output line level stage, however, will in real world applications be asked to drive many different and varying loads (combinations of resistance /capacitance / inductance) - much
like a power amplifier. To guarantee pristine signal transfer operation, it must therefore have a much more extended phase margin, absolute stability and high voltage and current drive capability
without any limiting action of protection circuitry. Of course it must also be short-circuit proof.
FM ACOUSTICS' proprietary Class A output stages feature a dedicated circuit. They are capable of driving almost any length of cable and impedance with absolute stability and highest interference rejection. The majority of other products using line-level output stages are typical test bench designs that work well on the test bench (with correspondingly short cables and fixed resistive loads) but fail to perform adequately in real world applications. The best circuitry is of no use if the following stage and interface (cables and connectors) are not driven optimally. These are much underrated facts which critically influence the performance in actual system installations.
FM ACOUSTICS proprietary circuitry results in extremely stable, accurate and super-fast interfaces which can handle and supply levels of up to +28dBv at highest linearity, and do this also into highly capacitive and/or inductive loads. The resulting inherently distortion-free circuitry avoids any possibility of signal degradation and guarantees preservation of the finest musical details. The result is absolutely unparalleled accuracy and pristine signal transfer.
The improvement in performance over existing line drivers is astounding. Clear improvements are also experienced when adding the FM 214 to output stages of the existing equipment (it improves signal transmission between source and load) by ameliorating the output stage.
Using FM ACOUSTICS technology any possibility of signal degradation is avoided, and preservation of the finest musical detail is guaranteed. The result is absolutely unparalleled accuracy in interfacing and superior system performance. The improvement in performance compared with existing line drivers is astounding; once this difference is experienced, it becomes clear why the FM 214 and the FM 216 are such a success.
