The Radial Engineering Jensen Twin-Servo 500 Series Mic Preamp is a faithful recreation of Deane Jensen's original Twin-Servo 990 mic pre, regarded by many audio professionals as one of the finest preamps ever made.

This mic preamp has pedigree. The circuit designed by the Jensen engineering team includes two cascaded 990 op-amps to share the load and provide 60 dB of clean gain. The two servos eliminate the need for signal-degrading capacitors in the audio path and allow for less than -120 dBu of noise.

Engineered for superior sound quality, the two oversized input and output Jensen transformers are a crucial part of the design. They contribute to lowering the noise floor and freeing the signal from hum and RF interference, while producing an extended frequency response and plenty of headroom.

Augmented by a 180º polarity-reverse switch, a -15 dB pad, and a high-pass filter that eliminates excessive low-end, the Twin-Servo opens musical tone-shaping possibilities. Other features include a dual-gang potentiometer for optimal gain, a 10-segment LED meter that gives instant visual feedback for the input signal and a 48V phantom power-activation switch to power condenser microphones. The front-panel Neutrik combo connector offers the choice of XLR microphone input and standard hi-Z 1/4" instrument input.

Re-imagined for today, this adaptation of the Jensen Twin-Servo fits the popular 500 series format.

Jensen Mic Input Transformer

The JT-16-PCJR is exceptionally quiet and linear from 5 Hz to 50 kHz with less than 0.06% distortion at 20 Hz

Jensen Dual Op-Amps

100% discrete audio signal path without any tone-shifting capacitors

Jensen Output Transformer

The JT-11-EM is linear from 2 Hz to 200 kHz with less than 0.001% distortion at 20 Hz

180° Polarity-Reverse Switch

Reverses pins 2 and 3 at the output to help phase-align microphones when two channels are in stereo use

10-Segment Meter

10-Segment Peak Indicator with Hold. Custom-designed circuit for greater VU accuracy

Dual-Gang Pot

Simultaneously controls the dual-990 op-amp topology for optimal gain at all levels

High-Pass Filter

Gentle high-pass filter may be inserted into the signal path to reduce excessive low-frequency content and control resonance

Pad

Reduces the input sensitivity by -15 dB when amplifying exceedingly high output sources

48V

Activates the 48V phantom power supply for use with condenser microphones and active direct boxes

Combo Input

Combination balanced XLR mic input and 1/4" instrument input is mounted on front panel for ease of use

Ground Lift Switch

Set-and-forget rear-panel ground switch lifts the pin-1 ground at the XLR input

Omniport

Available when used with the Radial Workhorse, the Omniport accesses a hi-Z instrument input

Full Enclosure

100% encased steel casing reduces magnetic interference from nearby modules that may cause noise pollution

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas. But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way. Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger
