 Manufacturer's Description

Presonus Eris 4.5 High-Definition 4.5" Active Studio Monitor ES-45

When Size Matters

If space is at a premium, or if you want the ultimate in portability, consider the ultra-compact Eris E4.5. It may be the size of a computer speaker, but this mighty mite delivers professional audio quality, thanks to a 4.5-inch, Kevlar low-frequency driver; a low-mass, 1 inch, silk-dome tweeter with protective grille; and Class AB amplification. Each speaker is powered by a 25W Class AB amplifier—plenty of juice for a small speaker. The E4.5 ranges from 70 Hz up to 20 kHz, and at 6.42 x 9.45 x 7.09 inches (163 x 241 x 180 mm), you can shoehorn this little beauty into almost any studio space.

The next step up in size and power is the Eris E5, which takes up just 7 x 10.24 x 7.68 inches (178 x 260 x 195 mm). The E5 sports a 5.25-inch, Kevlar low-frequency driver, mated with a 45W, Class AB amplifier; and a 1-inch (25 mm), silk-dome tweeter powered by a 35W, Class AB amplifier. It can crank out a clean 102 dB SPL, peak. Frequency response is rated at 53 Hz to 22 kHz. For a studio monitor in its size and price class, that’s impressive.

For an extended low-frequency response and a bit more muscle, step up to the Eris E8. With its 8-inch, Kevlar low-frequency transducer, driven by a 75 watt, Class AB power amplifier, it can range down to 35 Hz. Like the E5, the E8 can reach all the way to 22 kHz, thanks to a 1.25-inch (32 mm), silk-dome, high-frequency tweeter. However, the E8’s tweeter is driven by a heftier 65W, Class AB amplifier. With its extra juice, the E8 can deliver up to 105 dB SPL, peak.

All Eris speakers have front-ported enclosures made of vinyl-laminated, medium-density fiberboard (MDF).

Gazintas

Eris E5 and E8 provide balanced XLR, balanced ¼” TRS, and unbalanced RCA line-level inputs. When both balanced connections are in use, the TRS input will supersede the XLR input. The RCA input is summed into the signal path.

With this selection, you’ll have no problem hooking your Eris E5s or E8s up with virtually any line-level source. (If your signal source has unbalanced, ¼” TS outputs, simply use a ¼”-to-RCA adapter or adapter cable.) Notes Media-Mixture.de (Germany), "For connections and adaptability to the space, PreSonus makes no compromises."

The E4.5 has balanced ¼” TRS and unbalanced RCA inputs, as well as unbalanced 1/8” inputs for your smartphone or MP3 player, giving you all the flexibility you need when replacing computer speakers or those old studio monitors that have misled your ears for the last time.

Take a moment, if you will, to consider the E4.5’s balanced TRS inputs; balanced inputs help you minimize noise—a pro feature you won’t find on competing speakers in this class. That’s not the only professional-class feature you get with Eris speakers that competitors can’t match, though. Next, we’ll discuss some higher-end features that truly set Eris apart from other budget-priced studio monitors.

You’re in control!

Today’s music producers deal with a wide variety of musical genres and often work in more than one location. It’s easy to take your Eris speakers with you when you want to work in a different space. It’s almost as easy to customize their sound for your room and type of music.

The most basic control is the Input Gain, which determines the signal level before it reaches the power amp. This is part of gain-staging your overall system—that is, setting the levels for every part of the recording chain in order to get the optimal level of clean audio all the way through. Once you’ve gain-staged your system, you can leave this control alone.

The Eris E5/E8 provides three EQ controls in its Acoustic Tuning section: High, Mid, and Low Cutoff. These controls enable you to fine-tune the monitors and even to broadly approximate the sounds of different types of speakers so you can hear what your mix might sound like, for instance, on a car stereo or portable radio. The Low control also is useful when using the E5 or E8 with a subwoofer.

In addition to the Acoustic Tuning controls, Eris speakers offer a three-position Acoustic Space switch. This switch controls a second-order, low shelving filter that cuts the level of all frequencies below 800 Hz by a specified amount (-2 or -4 dB) to compensate for the boundary bass boost that occurs when the monitor is placed near a wall or corner. If you don’t want to roll off those lows, set it to 0 dB.

This combination of controls lets you create a linear response for accurate monitoring and enables you to simulate different listening environments, so you don’t have to listen to mixes on your car, consumer computer speakers, and home stereo to check how the music sounds with different systems. Instead, you can adjust the Eris monitors’ response and test your mixes without leaving your studio. No other monitors in this price class offer this degree of control.

IsoAcoustics ISO-130 Acoustic Isolation Studio Monitor Stands Pair, Small

IsoAcoustics Inc. is pleased to introduce the next evolution of our specialized line of speaker stands for the audio professional, music hobbyist, audiophile, and music lover. The new ISO Series of speaker stands provide superior acoustic isolation and enhance the sound clarity of any speakers including studio monitors, home theatre systems and sound reinforcement.

With a lower profile and new contemporary design, the ISO Series of stands positions your studio closer to the supporting surface or meter bridge, and the new redesigned isolators moves the acoustic performance another step forward.

IsoAcoustics ISO Series speaker stands are built with a unique, patented isolation technology that provides a high degree of isolations and manages the speaker’s energy to deliver authentic, uncoloured sound. This next generation of speaker stands effectively eliminates energy transfer into the supporting surfaces. Bass becomes tighter, overall imaging is enhanced and your speakers are enabled to perform to their full potential. Following the same design philosophy as the ISO-L8R Series, these isolation stands provide 14 variations of height and tilt adjustment to optimize the placement and performance of studio monitors by getting the tweeters in the correct alignment with the listening position.

Whether you’re a pro mixing in the studio – a musician creating in a home project environment – or an audiophile who appreciates every nuance of music and sound – you’ll hear and appreciate the difference with the ISO Series speaker stands. It’s simply the best investment you can make for superior audio.
