The 300W Crown Audio CDi 4|300 4-Channel DriveCore Series Power Amplifier with BLU Link utilizes technology derived from the flagship Crown DriveCore Install series amplifiers, providing an impressive mix of high-performance, rich feature set, and competitive cost. The CDi DriveCore 4|300 offers streamlined functionality for most small- to medium-sized installation such as restaurants, retail stores, and more.

The DriveCore integrated circuit eliminates hundreds of components within the amplifier, reducing the variability of component values and increasing reliability, resulting in remarkable audio fidelity from an efficient design. The 4-channel amplifier is simple to use and includes a network control & monitoring, an advanced DSP circuit, and an easy-to-use, front-panel interface. The amplifier is equipped with two BLU Link RJ45 connectors, which can receive and send 256 fault-tolerant audio channels.

The amplifier is capable of driving up to 100Vrms speaker loads without requiring a transformer and comes pre-loaded with JBL speaker tunings to help make installations quicker and easier. The CDi 4|300 features an Ethernet port for using HARMAN's HiQnet Audio Architect software for configuration and operation over a standard TCP/IQ network. The rear panel includes terminal block inputs and barrier strip outputs.

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

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.

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.
