Precise monitoring in a compact design
The Presonus Eris Studio 4 is an active studio monitor from the Eris series, which is equipped with a tweeter and woofer for a frequency range of 55Hz to 20kHz. Delivering an output of 25W per speaker and an impressive sound pressure level (SPL) of 99dB at a distance of one metre, the monitor's special design features an expanded 120° horizontal dispersion to create a broader sweet spot, while the narrow vertical dispersion angle reduces reflections in situ to give precise monitoring. An excellent transient response is also delivered courtesy of the tweeter's silk-dome design, while the woven-composite woofer provides a clear bass reproduction. In addition, flexible connection options at the rear of the monitor allow seamless integration into any setup.

Expressive sound for every room
In combination with the bass reflex opening, the 4.5" woofer covers the low frequencies of the Presonus Eris Studio 4, reproducing frequencies of 55Hz and above, while the 1" tweeter is characterised by its low weight and delivers a clear transient response. The rear of the monitor is equipped with flexible connection options, above which the sound adjustment options and gain control can be found. Highs and mids from 10KHz and 1kHz, respectively, can be continuously reduced and amplified by up to 6dB to enable suitable integration into an acoustic room, while the low-pass filter setting can be adjusted to 80Hz or 100Hz. The Acoustic Space control filters frequencies below 800Hz by either -2dB or -4dB to counteract any over-emphasis of these frequencies that occurs when the Presonus Eris Studio 4 is placed close to a wall.

Flexibility ensured
The Presonus Eris Studio 4 not only provides the perfect compact solution for studios where space is at a premium, but is also ideal for studios where details in the sound are at the heart of successful productions – a requirement easily fulfilled by the special EBM (Elliptical Boundary Modelled) waveguides, which deliver a superior treble response. The balanced 6.3mm TRS jack, unbalanced RCA jack, and the XLR input at the rear of the monitor also enable flexible integration into any setup. A range of adjustment options, which can also be found at the rear of the monitor, allow the sound to be adapted to the specific acoustic space, resulting in an optimum sound even in the smallest of production areas. In addition to extensive flexibility, integrated protection circuits comprising RF shielding, output current limitation, and over-temperature and subsonic protection functions, ensure that the Presonus Eris Studio also delivers in terms of reliability.

About Presonus
Presonus is a US company founded in 1995 by Jim Odom and Brian Smith in Baton Rouge, Lousiana. The firm designs hardware and software at both professional and more affordable levels for musicians and producers. Presonus first made a splash in the mid-1990s with the DCP8, an eight-channel analogue compressor/limiter/gate with fader and mute automation that could be digitally controlled by MIDI. In the early 2000s followed a series of microphone amplifiers and the first audio interfaces for the then-emerging home studio scene. Today, the company's product range includes audio interfaces, microphone preamps, digital mixing consoles, and studio monitors as well as the established DAW software Studio One.
Optimum setup for the perfect sound
The Presonus Eris Studio 4, which weighs in at 4kg, can be installed on a stand or studio table. Produced from vinyl-laminated MDF and featuring rounded edges for an elegant design, the Eris Studio 4 makes an impact in any music studio. For the optimum stereo triangle, two of these monitor models can simply be arranged at a distance of one meter apart and equidistant from the listener, ensuring a 30° angle between both monitors and the listener. Ideally, the monitor should be positioned 20 to 30cm from the wall, but if this is not achievable with the Presonus Eris Studio 4, the Acoustic Space switch can be used to compensate for increased bass caused by reflections. The use of short cable routes is recommended with the Presonus Eris Studio 4 in order to avoid noise interference in the monitor signal.
