[. . . ] BASS AMPLIFIER BBT500H Owner's Manual Mode d'emploi Bedienungsanleitung Manual del Usuario Manuale di Istruzioni Handleiding FCC INFORMATION (U. S. A. ) 1. IMPORTANT NOTICE: DO NOT MODIFY THIS UNIT! This product, when installed as indicated in the instructions contained in this manual, meets FCC requirements. Modifications not expressly approved by Yamaha may void your authority, granted by the FCC, to use the product. IMPORTANT: When connecting this product to accessories and/or another product use only high quality shielded cables. [. . . ] and Canadian models only To protect against electromagnetic waves, attach the supplied Clamp Filters to the cables connecting the amplifier's SPEAKER 1, 2 jacks to the speakers. 17) @5 Power Connector (AC IN) Connect the supplied power cable to this terminal to supply the unit with power from an AC power outlet. * The Speaker Simulator can only be applied to the LINE OUT jack output when the !9 Line Out Source Switch is set to "POST EQ". @1 Output Limiter Switch (OUTPUT LIMITER: ON/OFF) This switch is used to switch the Output Limiter circuit ON/OFF. When set to the ON position, the limiter suppresses the signal if it exceeds the threshold before sending it to the SPEAKER jack and LINE OUT jack. OFF . . . . . . . . . . . . . . Deactivates the Limiter on both LINE OUT and SPEAKER jack signals. Activates the Limiter on both LINE OUT and SPEAKER jack signals. When connecting the power cable, make sure the amplifier's POWER switch is turned OFF. * Total Impedance Whenever two or more speaker cabinets are connected to the unit, consideration must be given to the total impedance of the speaker system. Normally, a speaker cabinet has an impedance of 4, 8 or 16. But when two or more speaker cabinets are used together, the total impedance will change according to the manner in which the cabinets are connected. q Connecting in a Series Total impedance = 1st Speaker + 2nd Speaker + 3rd Speaker . . . Connecting three 4 speaker cabinets in a series as shown below, results in a total impedance of 12. @2 MIDI OUT Jack Connect this jack to the MIDI IN jack on an external MIDI device that can save MIDI data (such as a MIDI data filer, etc. ), and save patch data from the BBT500H to an external device. 16: MIDI Bulk Out) Also, when MIDI Merge is set ON, MIDI data received from an external MIDI device via the MIDI IN jack is transmitted from the MIDI OUT jack without alteration. 16) @3 MIDI IN Jack Connect this jack to the MIDI OUT jack on MIDI Foot Controller, etc. , to select patches, control volume, etc. , with the MIDI Foot Controller. 15) Also, patches that have been saved to an external MIDI device can be loaded into the BBT500H's internal memory. 16: MIDI Bulk IN) @4 Speaker Jacks (SPEAKER 1, 2) Two Speaker Jacks are provided for connecting speaker systems. The two jacks are connected in parallel inside the unit. Make sure that the speaker cabinet you use meets the requirements given below. q When using a single SPEAKER Jack (1 or 2) Please use a system that complies with one of the following requirements. · The total impedance* of the circuit should never be less than 2. · A 2 speaker system must have a power handling capability of 500W or greater. · A 4 speaker system must have a power handling capability of 250W or greater. · An 8 speaker system must have a power handling capability of 125W or greater. q Connected in Parallel Total impedance = Connecting three 4 speaker cabinets in a parallel configuration as shown below, results in a total impedance of about 1. 3. 4 4 4 9 Operating Instructions Getting sound output 1 First, make sure that the POWER switch is switched OFF, then connect your bass to the INPUT Jack on the front panel. Rotate the OUTPUT knob fully to the left and then switch the POWER switch ON. Sound Setting When the power is switched ON, all control knobs function as labeled on the panel and described below. All lamps on the display above the control knobs and switches are unlit. [. . . ] and Canadian models only) To protect against electromagnetic waves, attach the supplied Clamp Filters to the cable connecting the bass guitar to the amplifier's INPUT jack, and the cables connecting the amplifier's SPEAKER 1, 2 jacks to the speakers. * When attaching the clamp filter, wrap the cable once around the clamp filter as close to the BBT500H unit as possible. Cable Clamp Filter Clamp Filter 17 Error Messages If an error occurs during operation, one of the following error message numbers will appear on the display. E1: MIDI Receive Buffer Full CAUSE: SOLUTION: Too much MIDI data is being received by the BBT500H at one time. Try reducing the amount of data being sent or, break the data into smaller blocks. E2: Communication Error. CAUSE: SOLUTION: An abnormality is detected during MIDI communications. and try again. E3: Bulk Receive Check Sum Error. CAUSE: SOLUTION: The check sum does not match the received MIDI bulk data. [. . . ]
