One interface that gives you all you need to record the whole band

It’s common knowledge that TASCAM pretty much started the whole home  recording revolution. But when they’re not leading the way, TASCAM seems  to take stock of what’s missing from the present crop of recording  tools. Then, with their collective finger firmly on the pulse of current  trends, they create products that fill in the blanks. That’s the  thinking behind the US-1641. There are plenty of interfaces out there, but the US-1641 is built to solve a prevalent problem—interfaces with too little I/O for too much money. The US-1641 provides you with excellent sonic quality, software extras, and the most I/O you can get at its price point.


About a box


Let’s start with the physical features of the US-1641.  It’s a single rackspace unit with a sultry, dark blue face and 10  silver knobs that provide gain control for each of its 10 channels. On  the front panel are eight XLR inputs with two phantom power switches  (one for each gang of four) and two TRS inputs that can function as  either balanced line inputs or unbalanced guitar inputs via two  front-panel Hi-Z switches. The preamps on channels 1-8 provide a ribbon  mic-friendly 60dB of gain. Also resident on the front panel is a mix  control. Turned hard left, it lets you monitor the analog inputs; turned  hard right, you hear what’s coming out of the computer. The beauty of  this control is that you can monitor your input signal along with your  recorded tracks for zero-latency monitoring (great for overdubbing).  There’s also a 1/4" headphone jack and monitor level control.


On the rear panel, you’ll find four line inputs and outputs that can  also be used as sends and returns for outboard gear, stereo monitor out,  and stereo digital I/O that can be set for S/PDIF or professional  AES/EBU operation. You’ll also find a USB port (USB cable included) and  MIDI I/O hanging out there as well. Be aware that you must have at least  a 1GHz processor and USB 2.0 in order for the US-1641 to function properly. In total, the US-1641 gives you 16 simultaneous inputs and eight outputs (if you count the stereo S/PDIF out).


Sixteen inputs and what do you get?


The value of the US-1641 doesn’t stop with plenty of I/O and convenient front-panel control and  cable access. To get you up and recording out of the box, the  24-bit/96kHz US-1641 includes a version of Steinberg’s Cubase LE4 and the GVI GIGA  Continuous Velocity Piano, which is another TASCAM first. Rather than  choking your RAM with massive amounts of multisamples, which tend to  allow only a few layers of velocity changes, it utilizes only a single  velocity sample that’s precisely and continuously expanded via spectral  morphing filters. Since I have a PC that’s dedicated to virtual  instruments, I loaded it up and listened. The 1GB Giga Piano from  TASCAM’s Gigastudio was my main grand piano sound, but not anymore. Not  bad for a freebie.

In your interface!


I’m a firm believer in using live rhythm tracks as a song bed. (It’s  the calculus of overdubs: As songs build one track at a time, feel goes  to zero.) Luckily, I had a band showing up at my studio to record their  debut album, which made for an excellent test of the 1641’s  capabilities.


The band is made up of drums, bass, guitar, and keyboards. I started with drums. The US-1641’s eight front-panel XLR inputs enabled me to use the ubiquitous rock drum miking scheme: Shure SM57Audix D-6 on the kick, three Sennheiser MD421s on the toms, two Neumann KM 184s for overheads, and an AKG C 414 on the hi-hat (using its figure-8 pattern to isolate the hat from the  snare).By this point, most interfaces at two to three times the price  are pretty much maxed out I/O-wise, but with the US-1641, I was just getting started. Next, I ran bass through an A Designs REDDI on the snare,  direct box and into channel 9 on the front panel. (With the REDDI, you  don’t need to mic a bass amp.) For guitar, I decided to get clever. For a  huge sound, we went direct into channel 10 and miked the amp in stereo  to maintain the sense of reality space. I know what you’re thinking: How  did I stereo-mic the guitar amp with all of the XLR inputs taken up by  drum mics? Simple. I took a line out from two different preamps (for  added texture) into the line inputs on the rear panel, since they are  switchable between –10dBV and +4dBu. Keyboards went stereo into the rear  1/4" inputs 13 and 14.


For a cuemix, I took two of the four outputs and sent them to a  four-channel headphone monitor amp, which can be purchased  inexpensively. Next step was to count off the band and hit “record.”  TASCAM includes Cubase LE4 recording software, which I used for this  test. Installation was quite painless and the US-1641 found its feet without issue.


On playback


The band rehearsed, the computer ticked away, and I sat at the desk  with my feet up. On playback, I have to admit that the preamps and  converters in the US-1641 sounded quite a bit better than I thought they would. We actually wound  up using some of the takes for the album. At the end of the day, there  was no appreciable difference in sound quality between the US-1641 and an interface I have that sells for three times the price. So, if  you want to record live performances and have the ability to do  post-production with VST plug-ins, I have two words for you: TASCAM US-1641.
