The Kopul SDI-PPC is a stereo, passive DI Box designed to bridge the gap between consumer-level audio sources and pro audio destinations. With this unit, you can route the audio of instruments, smartphones, tablets, receivers, and more into mixing consoles or PA systems.

On the input side of the SDI-PPC, you�ll find two 1/4" TS jacks. These are suitable for instruments such as electric guitars, basses, and keyboards. If you're using only one of the 1/4" inputs, the other can function as a parallel output, allowing you to send the copy of the signal to an amplifier. This usage lets you split a guitar signal during recording, so you have the amped track in addition to a clean, DI�ed take to use during the mixing stage. A 3.5mm input is on hand for playing backing tracks from smartphones, tablets, and other compatible media players. Rounding out the input section are two RCA jacks for turntables, A/V connections, computer soundcards, and more. Two XLR connectors are provided for outputs.

The SDI-PCC makes use of a passive design that employs custom-wound transformers for matching low-impedance sources to high-impedance destinations; thus, you can plug your guitar or stereo backing-track into the input, route the output directly to a mixing console or PA system, and mitigate the noise issues often associated with plugging straight in. These transformers are isolated to eliminate buzz and hum from ground loops. Furthermore, they help the unit to secure a warm sound that smoothen the frequently-harsh characteristics of audio streaming from digital sources. With 128 dB of dynamic range, you don�t have to worry about high signal levels clipping or distorting, and for extra measure, a -15 dB pad can attenuate levels that are too high for the device. The SDI-PPC features a sturdy aluminum housing suitable for withstanding the rigors of touring life.

Custom-Wound Transformers
The high-performance transformers are custom-wound to meet the needs of converting high-impedance unbalanced signals to low-impedance balanced audio. Thus, signal from many different devices can be connected to the microphone-level inputs of a mixing board, or sent directly to a PA system.
Warm and Natural Response Curve
The transformers are made to withstand extremely high signal levels while maintaining linearity from 20 Hz to 18.5 kHz. The resulting smooth Bessel response curve offers a warm and natural, making these transformers suitable for handling the sometimes-harsh sound of digital sources.
3.5mm Input
Sending audio directly from a tablet or smartphone to a mixing console can sport less-than-optimal results. This 3.5mm input will send audio from a tablet, smartphone, or MP3 player to a mixing board without any of the harsh side effects of plugging straight in, thanks to the custom-wound transformers.
Stereo RCA Connectors
The stereo RCA connectors are suitable for connecting the audio signals from a computer soundcard as well as A/V components such as a turntable and DVD player to a sound system.
Dual 1/4" Connectors
You can use the SDI-PPC as a traditional direct box for electric guitar or bass. Parallel wiring allows you to output the signal from the unused connector to another source, such as a guitar amp. Dual 1/4" connectors also make it possible to connect two instruments to the mixing board at the same time. You can even maintain the stereo quality of the sounds from keyboards by connecting stereo 1/4" TRS outputs to the SDI-PPC with an insert Y-cable.
-15 dB Attenuation
The -15 dB pad attenuates the signal level from loud sources like an electric guitar or keyboard.
Sturdy Housing
The SDI-PPC's housing is made out of heavy-duty aluminum. It will withstand the shocks and bumps of the road, standing up to use in live applications.

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat. As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play. I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming. The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.

Cozy Omegaverse
Format: Kindle
This is the true definition of Cozy Omegaverse. LA wedding coordinator meets her pack at the location for a couple’s destination wedding. Low angst because they are scent matched high heat with heats and knots. Everything you love about this genre with very little anxiety. Simply a fun experience to read and a book I will comeback to when I’m in a slump. I simply love reading this book

Cute Omegaverse story
Format: Kindle
3.75 stars and 2 for spice. Adorable Omegaverse story about a wedding planner who has to go to a small town to plan a wedding for a movie star. While there, she meets her pack. This covers her struggles of not living there but trying to keep her relationship going with her 3 Alphas. It's a quick read and cute, so I recommend it for people who like light-hearted RH stories.
