The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated" dangerous voltage" within the product's enclosure; that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Warning: This speaker shall not be placed in the close area during the operation so that the mains switch can be easily accessed by the user. Studiophile BX5a Introduction Thank you for choosing the Studiophile Series BX5a bi-amplified studio near-field monitor speakers. M-Audio is well known for digital audio interface technology, digital converters, audio preamps and mixers. Now, after extensive research and development, M-Audio is proud to present the Studiophile BX5a. The BX5a was designed and tested by veteran audio engineers to meet your needs in a studio monitoring environment. It is focused on the functional goal of delivering pure, original sound without any additional coloration. The BX5a monitor is self-powered, directly accepting a line-level signal from a variety of sources. The Studiophile BX5a is designed to overcome all the limitations of conventional studio reference monitors within the digital audio environment. This system delivers a wide-range 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 mid and high-frequency response as well. Both drivers are magnetically shielded for desktop music production. For pro engineers at commercial studios to home studio owners, the Studiophile BX5a sets a new affordable standard in studio monitoring. What's in the Box? Your Studiophile BX5a box contains: · · · Two BX5a speakers Two detachable AC power cords This manual Studiophile BX5a Features 1. Woofer The woofer unit is 5 inches in diameter with a magnetically shielded Kevlar cone, high-temperature voice coil and damped rubber surround. It is designed to deliver balanced mid and low-frequency response. M-Audio's new BX5a employs Kevlar for low-frequency driver construction. The same material used in bullet-proof vests, Kevlar's high resilience makes it ideal for use in speaker cones-- although it is typically reserved for monitors with higher price tags than the BX5a. Needless to say, Kevlar represents a significant improvement over the polypropylene and paper used in most monitors at this price. 2. Tweeter By employing a specially developed 1-inch silk dome with magnetic shielding, the tweeter can deliver distortion-free original sound and offer an extremely natural response. Its design minimizes reaction time by using a specially shaped silk dome for excellent delivery, and also minimizes resonance by adapting a unique internal damping technology. 3. Sub-Frequency Port The air vent hole in the rear panel is called a Sub-Frequency Vent Port and is designed to allow the discharge of extremely low frequencies occurring below 60Hz. 5 4. Enclosure Like the other components, the BX5a's enclosure has an important role in shaping the overall sonic response. In order to provide more stable performance, the BX5a's enclosure employs a special high acoustic efficiency MDF and unique interior reinforcement designed to absorb vibration and impact generated under extreme conditions. The custom design on the front panel will aid in diffraction and will benefit stereo imaging. 5. Network and Power Amplifiers The active crossover network and power amplifiers for the BX5a are specially designed for its woofer and tweeter. The network properly distributes low, mid, and high frequencies to the driver components in order to reduce distortion and loss of sound, thus achieving a naturally balanced sound. In order to generate powerful, ultra-crisp sound, there are two separate power amplifiers inside the BX5a for driving the woofer and tweeter separately in a high-end bi-amp structure. The power delivered to the woofer driver at a low-rated distortion is 40W, and 30W is also delivered to the tweeter. Front and Rear Panel Features Rear Panel Features 1. XLR INPUT: This jack accepts XLR input connections with either balanced or unbalanced wiring. The input wiring of an XLR connector should be as follows: < XLR PIN 1 . . . . . signal ground (shield) < XLR PIN 2 . . . . . signal positive (+) < XLR PIN 3 . . . . . signal negative (­) 2. TRS INPUT: This jack accepts 1/4" connections with either balanced or unbalanced wiring. For balanced wiring, a three-conductor TRS plug is necessary. The input wiring of a TRS connector should be as follows: < TRS TIP . . . . . . . signal positive (+) < TRS RING . . . . . signal negative (­) < TRS SLEEVE . . . . signal ground (shield) 6 Studiophile BX5a Unbalanced 1/4" wiring can be done with either a two- or three-conductor (TS or TRS) plug. A two-conductor (TS) plug automatically grounds the signal negative input, whereas a three-conductor (TRS) plug, wired unbalanced, provides the option of leaving the negative input open or grounded. We recommend that you ground the unused negative input (this can be done by wiring the ring and sleeve of the TRS plug together). The TRS input is summed through a balanced input amplifier with the XLR input, allowing both inputs to be used simultaneously. Input specifications apply to both. 3. 4. 5. 6. 7. 8. PRODUCT SPECIFICATION: This label contains the model and specification information. SUB-FREQUENCY VENT PORT: This port aids in reproduction of very low frequencies by discharging frequencies below 60Hz. VOLUME CONTROL: Use the volume control to set the output sound pressure from the BX5a to proper levels as required. POWER RECEPTACLE: Accepts a detachable 3-circuit line cord in order to power the monitor. FUSE HOLDER: Holds the external main fuse. VOLTAGE-SELECT SWITCH: Provides two selections, 115V AC and 230V AC, and should be set to match the "house supply" (receptacle) voltage of the country or location in which the speaker is used. The 115V setting is correct for the USA, while the 230V setting is correct for most of the UK and Europe. POWER SWITCH: This switch turns the monitor on and off. 9. Front Panel Features The front panel houses the Power LED, which indicates whether the speakers (amplifier) power is on or off. 7 Installation For optimal performance of the BX5a, please read the following thoroughly and carefully prior to installation. Precautions Handling: Please do not touch the speaker cones. The BX5a set is packaged in the box tightly, so your attention is required when taking the monitors out of the box. To avoid possible damage to the speaker units, hold both sides of the monitor in order to pull it out of the box. The speaker cones should not be touched in order to avoid damage even after they are out of the box. Correct Power Operation: Since the BX5a contains its own amplifier, it must be connected to a power outlet using the detachable AC cable provided. Before connecting power, please make sure that the Voltage-Select Switch located on the speaker's rear panel is set to the appropriate position, as described in the rear-panel features list appearing earlier in this manual. WARNING! - Use of improper Voltage-Select Switch combinations may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty. Connections: You can connect either an XLR balanced cable or TRS bala ...
