User manual M-AUDIO STUDIOPHILE BX8A DELUXE

[. . . ] Woofer The woofer unit is 8 inches in diameter with a magnetically shielded Kevlar cone, high-temperature voice coil and damped rubber surround. M-Audio's new BX8a Deluxe 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 BX8a Deluxe. Needless to say, Kevlar represents a significant improvement over the polypropylene and paper used in most monitors at this price. 2. [. . . ] The input wiring of a TRS connector should be as follows: <TRS TIP . signal ground (shield) 2 Studiophile BX8a Deluxe 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. 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 30Hz. VOLUME CONTROL: Use the volume control to set the output sound pressure from the BX8a Deluxe to proper levels as required. POWER RECEPTACLE: Accepts a detachable 3-circuit line cord in order to power the monitor. 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 and Japan, while the 230V setting is correct for most of the UK and Europe. POWER SWITCH: This switch turns the monitor on and off. Front Panel Features The front panel houses the Power LED, which indicates whether the speakers (amplifier) power is on or off. Power LED HF Driver (Tweeter) LF Driver (Woofer) 6. 5" (25. 4 cm) 12" (30. 48 cm) 3 English 15" (38. 1 cm) Installation For optimal performance of the BX8a Deluxe, please read the following thoroughly and carefully prior to installation. Precautions Handling: Please do not touch the speaker cones. The BX8a 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 BX8a Deluxe 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. - 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 balanced/unbalanced cable from the input of each BX8a to your corresponding preamp, computer or game console outputs. We recommend that you use high-quality balanced or unbalanced cables for input connections.
