m101

What are the main differences between the m101 and the m201 (or m801)?

The m201 and m801 are our top of the line analog mic preamplifiers. And while the m101 uses the same amplifier architecture* to achieve the same essential sonic character as the m201/801, it is manufactured to be affordable for musicians and/or project studios.

The m201/801 uses our highest quality 24 position gold-contact rotary gain switches (very expensive, but simply the best gain control there is), which provide precision gain adjustment in 2dB steps. The m101 uses an precision 12 position gold contact gain switch (less expensive) and comes standard with a 10dB trim control.

The m201 and m801 are both endowed with robust, high current output sections, capable of driving very long lines (1500') and loads down to 50 Ohms, while the model 101 has a bit less output current and is more suited towards standard studio applications. This difference results in a greater amount of output headroom for the m201/801 (+28dBu balanced) than the model 101 (+25dBu balanced).

*All of our preamplifiers are designed around fast, musical transimpedance amplifier architecture. Click here (pdf) to learn more about the benefits of this unique type of microphone preamplifier design.


Why are two m101s less expensive than one m201?

The m101 was conceived as an affordable yet fully capable high-end microphone preamplifier. The differences stated above are important in understanding how we are able to produce such an excellent mic preamplifier for less money. The m101's chassis and frontpanel are less expensive to manufacture than that of a m201. Also, there is a simple economy of scale at work- we build more m101s, which ultimately lowers the cost of their production.

Can the m101 be rack mounted?

Yes, the model 101 can be mounted in a standard 1U rack tray, and two model 101s can be mounted side by side to create a stereo unit. Click here (pdf) to see the m101 manual, which contains a detaled description of this option.


lunatec V3

What are the main differences between the lunatec V3 and the m201 and m801?

Like the model 101, the lunatec V3 uses the same amplifier architecture as the m201/m801, so it too exhibits essentially the same sonic character as all of the preamplifiers in our product line. However, the lunatec V3 is designed as a portable microphone preamplifier, which makes it unique in the following ways:


m801

What are the main differences between the m801 and the m201?

The m801’s power supply is housed in a separate 1U, ½ rack chassis, while the m201’s power supply fits inside its chassis.

The m201 comes equipped wth a M-S matrix built in, which includes a fronpanel mounted width control and separate matrix outputs. And last but not least, the m201 is now available with a reference quality 24-bit/192kHz ADC.

What are the main differences between the m801 and the m802?

The m801, as mentioned before, is the state of the art 8 channel microphone preamplifier. Using the highest quality components money can buy, the m801 is truly a no compromise affair- the ultimate 8 channel microphone preamplifier available anywhere, for any price. Unless, of course, you need it to be remote controllable, then the m802 becomes the ultimate 8 channel microphone preamplifier available anywhere, for any price.

Unlike the m801, the m802 is digitally remote controllable. All preamplifier functions (gain, 48V phantom, phase reverse) are accessible from the front panel or from a seperate remote control unit which can be stationed up to 1000’ feet away from the preamplifier. Plus, the remote control unit can control up to 8 m802s, for a system of up to 64 channels and all system settings can be stored and recalled in the available user presets.

The m802 is available with a reference quality 24/192 ADC module. And finally, the m802 is controllable from protools HD and compatible controllers, MIDI or a stand alone cross platform computer utility.

Will I encounter noise issues if my power supply unit (PSU) is too close to my main chassis (m801, m802, m904, m906)?

Yes, the power supply units can inject unwanted noise into the signal path of the aformentioned products. For this reason we provide DC power supply cables which enable installations with enough distance between the the PSU and the main chassis to eliminate the posibility of unwanted power line noise.

A high performance electronic device must be packaged to provide mechanical stability and protection from radiated interference. Grace Design preamplifiers and monitoring products chassis' are built with a combination of (non ferro-magnetic) stainless steel and alluminum for best audio performance and maximum protection from RF interference. While a standard cold-rolled steel chassis provides better shielding at power line frequencies (50-60Hz), we feel it is more important to protect the low level circuitry from high frequency interference. 60Hz hum is a nuisance, but it is easily detected and eliminated, while RF interference can manifest itself as subtle loss of detail or an increase in distortion and noise which might not be noticed until after critical tracks are recorded.

What are the main differences between the m801 and the m201?

The m801’s power supply is housed in a separate 1U, ½ rack chassis, while the m201’s power supply fits inside its chassis.

The m201 comes equipped wth a M-S matrix built in, which includes a fronpanel mounted width control and separate matrix outputs. And last but not least, the m201 is now available with a reference quality 24-bit/192kHz ADC.

m902

Why does the volume control on the m902 not do much until its turned up to read 60 or more?

This is because the range of control is exceptionally wide (95dB) to accommodate a wide variety of driver efficiencies (or inefficiencies). For example, if you are using an ultra efficient in-ear monitor, the usable volume range might read down in the 30's, whereas less efficient high fidelity headphones may require a level setting of 60 or above.

Remember that you can set the power up level so you don't have to turn your m902 all the back up every time you turn it on. Furthermore, there is a HI and LOW range setting which you may wish to use. Both of these options are available in the submenu. (read about that in the m902 manual)
