Have It Both Ways!

It's a bit of an understatement to say that Universal Audio's 710 Twin-Finity mic pres are a big hit among many of today's top studio engineers. It takes a 310V single-ended Class A triode tube preamplifier and a completely separate Class A FET preamp circuit and lets you blend the two signals together straight from the source. From 100% tube to 100% FET, you can dial in the solid-state bite you love, the ultra-fast response you want, and the even-order harmonic tube warmth you need, all with a single Tone Blending knob.





What could possibly be better? Answer: the Universal Audio 4-710d. The 4-710d combines four 710 Twin-Finity circuits together into a single unit that costs less than three original 710s. But that's not all. While they were at it, Universal Audio also added a simple 1176-based compression section to each channel, limiters on all eight digital outputs, and AES/EBU and S/MUX digital output. Now, it's even easier and more cost effective than ever to add a set of these fantastic hybrid preamps to your studio.

Universal Audio 4-710d 4-channel Microphone Preamplifier Features at a Glance:

• Phase-aligned "tone blending" of tube and solid state
  
• Newly designed 1176-style compression/soft-limiting circuit on each mic channel
  
• Monolithic balanced output stage
  
• Dual gain stages
  
• Balanced send/return inserts
  
• Discrete JFET DI with 2.2M ohm ultra-hi-Z impedance
  
• 70dB+ of gain, +48V phantom power, pad (15dB), phase invert, and low-cut filter (75Hz)
  
• Front-panel hi-Z input (switched from mic/line)
  
• Rear-panel XLR mic input, XLR line input, and XLR line output
  
• Digital output via dual ADAT optical or AES/EBU (DB-25)
  
• 8 channels of high-quality 24-bit/192kHz A/D conversion
