User manual M-AUDIO STUDIOPHILE BX8A

[. . . ] 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 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. [. . . ] 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 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. 9. Front Panel Features The front panel houses the Power LED, which indicates whether the speakers (amplifier) power is on or off. 5 English Installation For optimal performance of the BX8a, 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 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. Also, ALWAYS turn off the power of the BX8a and turn the volume of the BX8a down to a minimum before making the necessary connections. XLR Balanced Connection Assure that the power switch of the BX8a is turned off and that the volume control of the BX8a is turned down to a minimum. Connect the male end of an XLR balanced cable to the balanced input of the BX8a (refer to the following diagram for balanced connection). TRS Balanced/Unbalanced Connection Assure that the power switch of the BX8a is turned to off and that the volume control of the BX8a is turned down to a minimum. [. . . ] If you wish to change the voltage, please bring your unit to an authorised service technician for internal conversion. ATTENTION: Quelques piéces sont munies de transformateurs á double ou á multi-voltage (indiqué au panneau arriére). Si vous voulez changer le voltage, veuillez apporter votre appareil au fournisseur de pour le transformer. [. . . ]
