Royer Labs dBooster2 In-Line Signal Booster and DI

In-line signal booster and DI featuring two channels of dBooster ribbon and dynamic microphone signal boosting and impedance buffering technology - each channel also doubles as a high-impedance DI

Product Description

The Royer Labs dBooster2 In-Line Signal Booster and DI features two channels of dBooster ribbon and dynamic microphone signal boosting and impedance buffering technology. Each channel also doubles as a high-impedance DI.

When used as a signal booster, both channels of the dBooster2 increase the level of passive low-output ribbon and dynamic microphones with a minimum of distortion or coloration. Designed for professional applications, each dBooster2 channel offers two levels of clean gain boost: 12 dB or 20 dB, selectable by a front panel switch.

The dBooster2’s Class A input presents a high source impedance to microphones, minimizing loading (damping) and improving headroom. By utilizing the 12/20 dB gain switch, optimum balance between gain and headroom can be achieved for a variety of uses.

The dBooster2’s low-impedance output is an increased microphone-level signal that can drive a digital interface directly or a standard microphone preamplifier. It also minimizes signal loss on long cable runs.

When used as a DI for unbalanced guitar level sources, the dBooster2 provides either 0 dB or 8 dB of gain, selectable from the front panel switch. The single ended high-impedance (230K-Ohm) DI input maintains headroom and gain regardless of load, with minimal distortion or coloration.

RECOMMENDED APPLICATIONS:

  • Miking any low-volume sound source (acoustic instruments, vocals, etc.)
  • Recording direct to a DAW interface
  • Use on long cable runs to retain sound quality
  • DI for direct electric guitar, electric bass, and other instruments

FEATURES:

  • 12 dB and 20 dB gain stages in Mic mode
  • 0 dB or 8 dB gain in Hi-Z guitar input mode
  • High input impedance
  • Balanced Low output impedance
  • Rugged case construction
  • Ultra-low noise performance
  • Ultra-low distortion
  • Wide frequency bandwidth
  • Gain: switchable 12 dB or 20 dB in Mic mode,; switchable 0 dB or 8 dB in DI mode
  • THD+N: @20 dB Gain = .0015%, -25 dBu input signal, 1.3Vp-p output signal; @12 dB Gain = .001%, -6 dBu input signal, 3.66Vp-p output signal
  • IM Distortion: @20 dB setting, <0.002% @ 800 mV output; @12 dB setting, <0.005% @ 2.6volts output
  • Self-noise: referred to -48 dB re. 1V/Pa, 20 dB setting <11 dBa, 12 dB setting <15 dBa
  • Headroom: referred to -48 dB re. 1V/Pa and 4mV/Pa, 20 dB setting: 127 dB; 12 dB setting: 120 dB

BENEFITS:

  • Safe for use on all ribbon mics
  • Increases headroom at the preamp
  • Provides true electrical isolation
  • Protects ribbon mics from phantom-power
  • Minimizes mic loading
  • Capable of driving difficult loads, such as mic splitters and vintage style preamps, without increased distortion or loss of gain

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
