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. [. . . ] · 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. When using both SPEAKER Jacks (1 & 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 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. To obtain optimum performance from the amplifier, we recommend connecting the internal speaker to the SPEAKER 2 jack, and using the SPEAKER 1 jack to connect an external speaker (set) with a 4 impedance and power handling capacity of 250W or greater. * See page 10 for more information on total speaker impedance. and Canadian models only * The FX LOOP is active on both PRE EQ and POST EQ signals. @1 Speaker Simulator Switch (SP SIM: OFF/LINE/ON) This switch is used to switch the Speaker Simulator circuit ON/OFF. When the Speaker Simulator is activated, this special circuit adds the live characteristics of a speaker to the line out signal and headphones output. This feature is also effective when you want to produce a distorted sound with the tweeter level raised. The sound created with the Speaker Simulator is optimized to compliment the selected Sound Type. OFF . . . . . . . . . . . . . . Deactivates the Speaker Simulator on LINE OUT, SPEAKER, and PHONES jack signals. Activates the Speaker Simulator on LINE OUT, and PHONES jack signals only. Activates the Speaker Simulator on LINE OUT, SPEAKER, and PHONES jack signals. * The Speaker Simulator can only be applied to the LINE OUT jack output when the @0 Line Out Source Switch is set to "POST EQ". @2 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. To protect against electromagnetic waves, attach the supplied Clamp Filters to the cables connecting the amplifier's SPEAKER 1, 2 (EXT) jacks to the speakers. 10) @6 Tweeter Level Control (TWEETER LEVEL) This controls the built-in tweeter speaker's output level (mainly high frequencies above 4 kHz). @7 Power Connector (AC IN) Connect the supplied power cable to this terminal to supply the unit with power from an AC power outlet. @3 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 BBT500 to an external device. 17: 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. [. . . ] While holding the [MANUAL] switch and Memory Switch [5], switch the POWER switch ON. 17 Air Flow The device utilizes a forced air cooling system, which cools the interior of the unit by drawing air through the front intake by the fan, which push the air out the back. Front view Rear view Cooling fan Intake Exhaust 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 BBT500 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. [. . . ]
