You may be familiar with Canada’s Sim Audio, they’ve been producing top quality audiophile equipment since the 80’s. And if my phono preamp is any indication, this new offering in the form of a microphone preamplifier should be interesting. The headroom is very high, 32dBu! No overload indicator or level meters are provided. Take a closer look at the Moon Professional 3500MP:
Moon Professional 3500MP
- A “purist design” for optimal sonic performance and lowest possible noise floor.
- AC-coupled transformerless design for increased bandwidth and more accurate sonic reproduction.
- Wide gain range of 8.0 to 66dB with -3.5dB of variable output trim.
- Metal film resistors and polypropylene film capacitors.
- 2 fully independent audio channels, each on separate printed circuit boards.
- No electrolytic capacitors in the signal path (non-phantom mode).
- Built-in Power supply using 2 ultra-low noise toroidal transformers (1 for the audio signal circuits; 1 for 48V phantom and control circuitry).
- Housed in an isolated enclosure constructed from satin coated 14-gauge steel, designed to eliminate all traces of AC artifacts.
- Swiss-made 24-position gain potentiometers featuring gold-plated contacts and thinsurface-mounted film resistors with 1% tolerances.
- High-reliability sealed relays and toggle switches.
- High current output stage to accommodate very long cable runs and capable of driving 600ohm loads.
- Rigid external chassis with solid aluminum front and side panels and heavy gauge steel on the top, bottom and rear panels for shielding from RF, EMI and external vibrations.
- Circuit board with pure copper tracings and gold plating that yields low impedance characteristics.
- Designed to be powered up at all times for optimal performance.
- Low operating temperature to ensure long life.
