Eventide Mixing Link Mic Preamp

I've been using this for live playing (together with a ATM350) and home-recording with different mics, for over a year now. Only good things to say (it could have one or two improvements, but minor ones). The preamp is fairly transparent. Some users report a hiss, but I couldn't reproduce it. It's probably related to high gain switch, so be careful with it. the send/return loop is well balanced, no problems with impedance, noise, hums, super clean, really. The real strengh in this little box are the mixing options: with a 3pos toggle switch you can choose different mixing options between dry and wet (S/R loop) and have dedicated level knobs to it. The amp output is separated, so you can adjust the output of a guitar without affecting the mic level. However, no mic output level, only input - this can be limiting with some microphones. Also, the aux in doesn't have a level - so you'll have to control it in the unit you're plugging in - and it doesn't go through the S/R loop - this is perfect for playalong backing tracks.
Will keep using and if it breaks (I don't think it will) I'll just buy another.

This unit is currently being used as a mic pre with fx loop and DI out by our vocalist. It excels at all this features, having the I/O and controls for a myriad of possibilities, which makes it a good investment.
The knobs have very small "steps" which is great for precise control and the switch is very quiet.
It may be an expensive unit, but you're getting the functionality, build quality and pristine sound quality equivalent of studio grade equipment in a considerably small, portable and versatile unit!

"Designed, assembled and tested in the USA", Eventide Mixing Link Mic Preamp (ML) is a unique device. Although other units on the market cover the single functionalities offered by the ML, the ML manages to concentrate all of them in a simple to use, very compact box.

I'm sure I forgot something but the ML can work as:

- DI
- microphone amplifier (with 48V phantom power)
- signal splitter
- mixer
- stereo headphone amplifier
- iPad/iPhone interface
- Effect loop controlled (for instrument and microphone)

From the construction viewpoint, the ML uses an unusual approach. The enclosure itself appears to be a classical die-cast aluminium box similar to the type used in the majority of pedals. However, instead of printing the top of the enclosure with the unit's graphics, Eventide printed the indications on a separate piece of plastic around 3mm thick that was subsequently attached to the enclosure. The result is a very professional looking unit with the numerous labels clearly visible.

The send and return connections of the effect loop are placed under the main input and output (i.e. closer to the south side of the pedal). It is an unusual choice especially for live usage where the loop control should be close the performer. It's not a deal breaker but I would have liked to see them closer to the north side of the unit.

The sound is excellent - in line with the well-deserved reputation that Eventide has worldwide. I couldn't hear any noise or distortion. The frequency response is as flat as it is rarely the case with stomp boxes. With the "inst. input" and "to amp output" I could only notice a gentle roll off that leads to -0.5dB at 7Hz. For the non-technically minded, it is an exceptionally good frequency response. Bass guitar players will appreciate the transparency at the low frequencies.

The headphone amplifier works very well. The sound is consistently defined regardless the volume level and input signal. The frequency response is flat as the amp output. Any roll-off is well outside the audible range and the range of usual amplification systems.

The DI functionality works very well. As for the other input/output the sound is clean, linear without any coloration or distortion.

The microphone preamplifier is very transparent. I tested it with a Rode studio condenser microphone and the result was excellent. The ML microphone preamplifier is not the type of preamplifiers that add the unfathomable colour that (allegedly) only some super-expensive high-end preamplifiers are capable of. The ML does not add or take away anything - and I think it is a good thing.

The unit operates can operate with batteries but in this case you cannot use the +48V phantom power. The phantom power coming from an external device to the DI/Line out does not power the unit.

For the the +48V phantom power, the ML needs to be powered by an external 9V-DC, 2.1mm centre negative power source. In other words, any good quality guitar pedal would do the trick.

The unit I received had a 9V-DC power supply unit. Although it is nice that Eventide thought about it, in these days the vast majority of musicians already have a standard 9V-DC power supply unit. Adding a power supply unit means increasing the cost, more pollution and ultimately something that a very few people need. I would have liked a few €/$/£ less on the price and no power supply unit.

Overall, the ML is a great unit that I'm sure many musicians will find useful and that it will quickly find its place in their set up.

I recommend also the ML to all the musicians that don't need a mic preamplifier, a DI or any other of the ML functions often but they need a tool that can cover all them when it's required.
