Introduction
Thank you for choosing the SP-5B Studiophile Series pair of bi-amplified
powered near field reference monitor speakers. M-Audio is well known for their
digital audio interface technology, digital converters, audio pre amps and mixers.
Now, after long research and development, the Studiophile SP-5B is born to
change the concept of near field reference monitoring.
The SP-5B was designed and tested by many audio engineers to meet your needs
in a studio-monitoring environment. It is focused on functionality - to deliver
pure original sound without any additional enhancement. The SP-5B monitor
speakers need no other power amplification - they accept a line level signal from
a variety of sources.
The Studiophile SP-5B is designed to overcome all the limitations of
conventional near field reference monitors within the digital audio environment.
This system delivers a wide range of frequency response by employing two
extraordinary drivers and unique crossover technology licensed by M-Audio. It
boasts a stable and balanced low-mid frequency response along with a defined
MF and HF response as well. Both drivers are magnetically shielded for DTMP
users (Desk Top Music Production).
From professional users in commercial studios to home studio owners, the
Studiophile SP-5B is a true solution for near field studio monitoring in its own
class.

Studiophile SP-5B Features
1. Woofer
The woofer unit is 5 1/4 inches in diameter with a magnetically shielded
mineral-filled polypropylene cone, with a high temperature voice coil and
damped rubber surround. It is designed to deliver balanced mid and low
frequency response. Polypropylene is used to react against the input signal
accurately and to deliver even minimal input precisely while minimizing
distortion.

2. Tweeter
By employing a specially developed 1" silk dome with magnetic shielding, the
tweeter can deliver distortion-free original sound and offer extremely natural
sound. It minimizes reaction time by using fabric silk for excellent delivery, and
also minimizes resonance by adapting a unique Internal Damping Technology.
3. Sub-Frequency Port
The hole in the rear panel is called a Sub-Frequency Port which discharges
extreme low frequencies under 30 Hz. The SP-5B is designed to take advantage
of this port to generate extreme low frequencies.
4. Enclosure
The enclosure has an important role just as the other components. The SP-5B’s
enclosure is designed to endure impact from inside under extreme conditions. It
employs high-density special MDF and unique interior reinforcement to provide
more stable performance.
5. Network & Power Amplifiers
The Network & Power Amplifiers for the SP-5B are specially designed for its
woofer and tweeter. The Network properly distributes low, mid, and high
frequency to units in order to reduce loss of sound and distortion, thus achieving
a natural balance of sound.
In order to generate ultra crisp, powerful sound quality, there are two separate
power amplifiers inside the SP-5B to drive the Woofer and Tweeter drivers
separately as a high-end Bi-Amp structure. The power delivered to the woofer
driver at a rated distortion is 42W and 36W is delivered to the Tweeter.

Rear Panel:
1. XLR INPUT: This jack accepts XLR input connections, with either balanced or
unbalanced wiring. The signal of the XLR INPUT is summed together with
the TRS INPUT through a balanced input amplifier. So, either may be used as
an input or mixed together. Input specifications apply to both inputs. The
INPUT CONNECTIONS wiring chart of an XLR connector is as follows:
INPUT SIGNAL XLR CONNECTIONS
+ PIN 2
- PIN 3
Shield PIN 1
2. TRS INPUT: This jack accepts a TRS connector, either balanced or unbalanced
wiring. For balanced wiring, a 3-conductor TRS plug is necessary. The input
connections of the TRS connector are wired as follows:
INPUT SIGNAL TRS CONNECTIONS
+ TIP
- RING
Shield Sleeve
Unbalanced wiring works with either a 2 or 3-conductor TRS connector. A
2-conductor TRS plug automatically grounds the minus signal input, whereas
a 3-conductor TRS plug wired unbalanced provides the option of leaving the
minus open or grounded. We recommended that you ground the unused
input.
The TRS INPUT is summed together with an XLR INPUT through a balanced
input amplifier. So, either may be used as an input or mixed together. Input
specifications apply to both inputs.
