Universal Audio’s 710 Twin-Finity was one of the top preamp devices: versatile, innovative, and even affordable. However, it did not come in stereo. A few years later, Universal Audio addresses this concern with the 4-710d Preamp, which includes everything the 710 did plus stereo and more. It’s a four-channel preamp that includes compressors for each channel, a digital 8-channel A/D converter, switchable inserts, a clock subsystem, and soft limiting, just to name a few of its new features.
Each preamp channel has DI input and six switches. It has controls for insert, compressor, input and output gain, and a feature that blends solid-state and tube sounds. You’ll find inputs for XLR mic, line, and a balanced insert send/return, plus four extra TRS inputs. There are also AES/EBU outputs, a word clock I/O, and two ADAT outs.
The preamp outs very nice with just about any instrument. When used with a piano, for example, it can really create a nice, sweet top end that cuts through other sounds. Likewise for a guitar: it can help it cut through a lot of other sounds, giving it a bit of an edge. This preamp may not be the best for drums, however.
When it comes down to the bottom line, the Universal Audio 4-710d Preamp is versatile and certainly useful for a number of different applications. With the ability to go back and forth between tube and solid-state, you can play around with different sounds and options. You’ve got the best of both worlds to experiment with here. While the converters work well with many instruments, they aren’t the best for some percussion. Still, when you look at the price tag of $2,499, you’re really getting a lot for your money.
