Features 10/10

This advanced audio system system offers:

  • Mastering grade 24-bit/192kHz converters: 120dB SNR A/D, 120dB SNR D/A, 0.0003% THD+N
  • 16 ins, 16 outs
  • Two mono 1/4" analog mic/hi-z inputs with high quality preamps with gain controls (line -15 to +50, mic 0 to 65), clip indicators and switchable soft limiters
  • Phantom power
  • Optical S/PDIF I/O
  • Coaxial S/PDIF I/O
  • ADAT optical I/O
  • MIDI I/O
  • Stereo phono in
  • 5.1 configurable
  • Headphone amplifier with volume control
  • Built-in DSP with zero-latency monitoring with effects

1616M offers pretty much everything that's possible in such a compact device. Its casing is built mostly from a hard metal covered with a cheap looking painting. Front and back plastic panels in my unit were glued to that metal but the glue apparently wasn't strong enough to hold them and after a closer look I could see some gaps. In overall the casing does what it's supposed to but it doesn't leave the best impression possible.

Sound quality 9.9/10

1616M PCIE sounds incredible. Its sound is a bit more detailed compared to 0404 PCIE. It releases the music from speakers so it becomes more present and dimensional rather than trapped in noisy boxes. Its middle range is different than that in 0404. It's the best sounding audio device that I've come across so far. I'm sure there are even better interfaces out there and I'll hopefully return to this review with an update sometime.

The preamps are pretty decent in 1616M as they sound dynamic, natural and full of detail. Soft limiting does what you'd expect from it within some reasonable ranges because it's quite easy to hit the preamps too hard even for the soft limiting mechanism. Fortunately soft limiting can be turned off. Gain controls are common for both line/hi-z and microphone inputs so in some cases it gets a little little bit tricky to set the gain that you want.

The headphone output is loud and it sounds very good and clear.

Round trip latency

The lowest round trip latency is 6.077ms (approx. 3.6ms input, 2.4ms output) at ASIO buffer size of 88 samples and sample rate of 44.1kHz. It's a pretty good result. Increasing sample rate all the way up reduces the latency further to approx. 5ms. It takes audio about 2ms to go through 1616M PCIE with hardware direct monitoring feature. Disabling the microdock changes the input and output latencies to approx. 3.1ms and 2.9ms. I guess is that EDI transmission takes additional 0.5ms and with the microdock enabled the output latency is lowered to compensate for this. 1616M is therefore a little bit more CPU demanding than 0404 PCIE - it's difficult to achieve lowest stable latencies on an Intel i3-2100 or AMD Phenom II 945. Some system tweaking helped so it's possible to play through plugins in a simple session at a latency of 8ms. 6ms was in my case almost playable with some occasional drop-outs which didn't affect recorded material.


E-MU 1616M PCIE ASIO settings window


The built-in DSP is capable of sophisticated mixing, routing, direct monitoring and adding effects. It's possible, for instance, to rout any input source to an ASIO channel or ASIO output to WDM input. Offered effects include EQs, reverb, delay, chorus, distortion, guitar speaker simulator. Guitarists won't be impressed by their level of realism but they should like the possibility to record dry while rehearsing through these effects with a latency of only 2ms. Every effect is processed by the DSP, it's also possible to use E-MU DSP accelerated effects in any DAW but it doesn't seem to work on Vista/7.

Ease of use 8.5/10

PatchMix DSP can be probably confusing to some users due to the fact that it offers a lot. It's not that difficult anyway, it comes with many templates and you can save your sessions and even channel FX chains. It's a lot like any DAW software. It's not rocket science, but reading the manual might be a good idea.

Price 10/10

It goes for 290 euro new, it's a good price for an audio device that offers such a high quality sound and functionality.
