Description: 

Improving on a Great Sound
At PreSonus, we’ve been designing preamps for a long time, and we always focus on audio quality first. So when we decided to upgrade our popular TubePre V2, we focused on improving an already high-quality sound—without jacking up the price. Like the original TubePre, the new version is a fully professional tube preamp, with a dual-servo (no capacitors) gain stage that lets you boost the program signal to smoking hot levels without significantly increasing the background noise. Discrete components and high-voltage operation offer dynamic range and detail not found in other single-channel tube preamps in its class.

Xmax Preamplifier
But the TubePre V2 provides an even wider palette of sound options, and a much more focused tube saturation, than the original TubePre. It has been upgraded to employ PreSonus’ popular XMAX™ Class A solid-state preamp, which is followed in the signal path by a 12AX7 vacuum-tube stage. Twist the TubePre V2 Drive saturation control to add the “color” that only a hand-selected 12AX7 vacuum tube can deliver — from gentle warmth to total fuzz.

XMAX™ Class A Preamplifiers to Go
At PreSonus, we know that the mic preamplifier is a key component in the sonic quality of a recording. Many other companies that offer mobile recording interfaces add the cheapest possible microphone preamplifier as an afterthought. In contrast, the FireStudio Mobile includes custom-designed, high-voltage, discrete, XMAX Class A microphone preamplifiers that are suitable for use with all types of microphones.
The job of a microphone preamplifier in an audio interface is to boost a microphone-level signal to line level before conversion to the digital domain. A good preamp boosts the level to almost 400 times that of the original signal, making the preamp one of the most important stages in an interface. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results. But with XMAX preamps, the sonic quality is limited only by what microphone you plug into it.

XMAX preamplifiers are built with three key elements:

• High Voltage. The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
• Discrete components—not op-amps. We only use genuine transistors, resistors, and capacitors. Op-amps add noise, coloration, and harshness to a signal. Our discrete design delivers ultra-low noise and transparency.
• Class A. Class A circuits have no crossover distortion and deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.
  The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency, with smooth highs, solid deep lows, and everything in between.

12AX7 Vacuum Tubes
The 12AX7 is a miniature dual-triode vacuum tube with high voltage gain that was developed around 1946 by RCA engineers. It was first released for public sale in 1947 — and hasn’t changed design since.Part electronic fabrication, part glass-blowing, and part voodoo, tube manufacturing is nearly a lost art — only four major factories in the world still produce the 12AX7! All 12AX7 vacuum tubes are not created equal, so the tubes we use in the TubePre V2 are hand-selected and carefully tested. The tube in the TubePre V2 was hand-selected and carefully tested for electrical conformity and freedom from microphonics. (Microphonics occur when the charged elements in a vacuum tube vibrate, changing the distance between the elements. This causes charges to flows in and out of the tube, as they do in a condenser microphone, creating electrical noise and, potentially, feedback.)

Versatile and Feature-Rich
Housed in a rugged case, the TubePre V2 rear panel sports separate unbalanced, ¼” instrument and balanced, XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. We’ve included all of the extras you need for professional operation including a high-pass filter, phantom power for condenser mics, polarity reverse switch, and a backlit VU meter.

The TubePre V2 is more than a mic preamp, though.
Thanks to its separate instrument and mic inputs, it also serves as a dynamite direct box (DI) for guitars and basses. And it’s small enough to carry almost anywhere, although you also can screw-mount it to a standard rack tray.

So if you are a fan of our original TubePre, you’re going to love the improved TubePre V2. And if you are checking out the TubePre for the first time, your ears are in for a real treat. Then check out the amazing low price—but sit down first because you’re in for a shock. Because with PreSonus, big sound does not have to cost big bucks.

How To Set Up Your APM Series Speakers:

Unboxing Video of APM5B:

Description:

The Rockville APM5 Active Studio Monitor Comes in Pairs and each monitor will be bi-amped. What this means is that there is a separate amp for the highs and a Separate amp for the lows! Each speaker has 125 watts peak output power and 62.5 watts RMS giving you a total of 250 watts peak and 125 watts RMS per pair. We spent a lot of time developing the most premium studio monitors we ever built! I am very pleased and excited to talk to you guys about what we did to make these speakers sound as good as they do. If you are an audiophile you will find what we did to be quite amazing. Keep in mind, the only reason our price point is not 300 % higher is because you are buying manufacturer direct. We are one of the leading speaker manufacturers in the USA, and we have a state of the art manufacturing process. There is a lot to talk about so I will break it down into sections.

Description of the enclosure:

We chose a wooden enclosure as opposed to a plastic enclosure. Your studio is made of wood for a reason. The sound characteristics of high quality wood are better than plastic. We only use the highest quality MDF wood. We do not bother with cheap particle board material when we want to make the best speakers. The thickness is 0.5” around and the front board is a full 1” thick to give you the best sound quality possible. The enclosure is built with the perfect amount of air space to maximize sound quality for a studio.

Every studio or computer room should look beautiful. We believe speakers should enhance the look of a room. We make these speakers in 3 beautiful finishes. Painted black, painted white, and wood finish. We use “baking paint” made for wood surfaces. It is long lasting and the best paint for speakers! We went with a beautiful finish that is mostly matte with a slight shine to it. Our designers spent countless hours on the color to make sure it is not only beautiful but elegant as well to improve the appearance of your studio or room. We kept all the controls on the back of the speaker, which will keep the speaker looking very modern and elegant. The rear port is built to perfect spec to enhance the sound. The tweeter has a curved front bezel to make the highs crystal clear and distortion free.

Amplifier and Speaker Components Details:
To get the most efficiency we use a class “D” amplifier. We use the best quality components from the most reputable circuit manufacturers in the world in order to produce crystal clear sound. Most brands do not like to reveal what’s in the guts of the speaker. We feel differently. We want you to know what is inside so you realize how good of a value we are offering and also so that you can understand how good these really are. We use ADAU 1701 for audio processing and TPA3116 for amplification. These are both known to be best in class circuit designs. These components are amazing and allow us to adjust the sound via soft programing on a computer during the design stage to get the perfect sound. ADI and TI are the names of the makers of these IC’s. Most people do not know brand names that make circuits; but these are the most famous and reliable in the industry. Only very high end manufacturers like us use these components.

For highs, we have Ferro fluid enhanced ¾” neodymium silk dome tweeters with metal grill protection. If you are an audiophile I am sure you have tested and love the sound of silk dome tweeters. The neo magnet is strong and can handle a lot of heat. This enabled us to beef up the amplifier power without worrying about melting and blowing the tweeter. The highs on these sound really good! I cannot wait for you all to hear it in person, because I cannot describe how good these sound! You really need to listen to them in person.

We use a 5.25” woofer. This will out-perform a regular 5” woofer any day! The bass sounds amazing on these! Very clear and punchy! The woofer has an injection molded polypropylene cone. This is an engineered type of plastic that is used on many speakers today. It is strong and puts out a great sound. The rubber woofer surrounds increase sound quality and eliminate unwanted distortions. They sound better than foam surrounds in my opinion, which is why we went with rubber. The computer optimized electronic crossover network supplies amazing sounding highs, lows, and mids. Basically it filters out unwanted frequencies from each component so that each speaker plays the right frequencies so that the speaker can go loud without distorting. We use very high-grade crossover filters in our speakers. The specially wounded voice coils produce accurate response along the entire frequency spectrum. We developed the speakers with the most optimized magnet structure, cone, and cabinet space with the goal of reproducing the sound to play back exactly the way it was recorded!

Added benefits:
The rear-firing port is shaped and designed by sound engineers to reduce port turbulence and deliver distortion free top sound quality!

Our factory uses the latest Precision Glue Machine (Over 500 meter Tunnel Oven). But you may ask why am I talking about glue? Well, actually, the glue on speakers is of the upmost importance. If the glue does not hold up, the speaker will be done and blow. We use the latest machinery to manufacture these speakers. The SPL of the speaker goes up when you use better glue and a better machine that can secure the glue in place. If the glue can handle more heat than your speaker can handle more power!

Thick “Wadding” protects the inside of the speaker cabinet. This can be seen if the speaker cabinet is removed. Basically, wadding is a white chemical silk type of material that we put inside the speaker cabinet for multiple reasons. It helps to make the sound more clear, and at the same time protects all the parts inside the speaker. This material is also a fire retardant. This is unique to our speakers. Most other brands do not take this step due to the cost of the material, but it is a game changer if you are trying to create the best speaker!

Inputs and Outputs and Rear Panel Controls:
As I mentioned earlier, we kept all the controls on the rear of the unit to make the speaker look clean and modern. The volume control, bass, and treble controls are all found on the rear of the unit.
These Monitors have all your standard studio inputs and outputs such as a ¼” and XLR combo input jack, RCA input, 3.5MM headphone output. We also added a USB port. The reason we did this is because instead of having to use the 3.5MM or 1/4" TRS jack, you can now directly select the speakers as an output on your computer without using an interface! And you will get true stereo sound!

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a full one year warranty, though it is unlikely that you will need to use it.
