@0 Line Out Source Switch (LINE SOURCE: THRU/PRE EQ/POST EQ) This switch is used to select the signal that is delivered from the LINE OUT jack. THRU Delivers the signal received via the INPUT jack without alteration. Select this setting when connecting to a DI (Direct Injection) box. PRE EQ ....... Delivers the signal before it has been processed by the tone controls (the Sound Type is active). This setting can be used when separate EQ settings are required for speaker and line outputs. POST EQ ..... Delivers the signal after it has been processed by the tone controls. This setting can be used when you want the line signal processed with the same EQ setting as the speaker. * 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. LINE Activates the Speaker Simulator on LINE OUT, and PHONES jack signals only. ON 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. ON Activates the Limiter on both LINE OUT and SPEAKER jack signals. @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. (→ pg. 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. (→ pg. 17) @4 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. (→ pg. 16) Also, patches that have been saved to an external MIDI device can be loaded into the BBT500's internal memory. (→ pg. 17: MIDI Bulk IN) Panel Controls and Connections @5 Speaker Jacks (SPEAKER 1, 2 (EXT)) Two Speaker Jacks are provided for connecting speaker systems. The amp's internal speaker (4 Ω) is connected to the SPEAKER 1 jack. The SPEAKER 2 (EXT) jack can be used to add an external speaker(s). Also, if necessary, you can disconnect the internal speaker to connect 2 external speakers directly to the amp. The two speaker jacks are connected in parallel. When external speakers are used, make sure the speakers meet the following requirements. ● 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 2Ω. • A 2Ω speaker system must have a power handling capability of 500W or greater. • A 4Ω speaker system must have a power handling capability of 250W or greater. • An 8Ω 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 2Ω. • A 4Ω speaker system must have a power handling capability of 250W or greater. • An 8Ω 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 4Ω impedance and power handling capacity of 250W or greater. * See page 10 for more information on total speaker impedance. * For U.S. and Canadian models only 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. (→ pg. 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. When connecting the power cable, make sure the amplifier's POWER switch is turned OFF. 9
