Detailed Parameter Settings Equalizer Mode The Equalizer mode lets you make settings for the internal 1-Band Parametric Equalizer, and set the center frequency (or in the case of the TREBLE control knob, its cutoff frequency) for each of the panel's Tone Controls (BASS - TREBLE) in the internal five-band equalizer. To enter the Equalizer mode, press the [FUNCTION] switch. Knob functions are displayed in the bottom row of the panel display above the knobs. ● How Knobs Function in the Equalizer Mode The knob's value is shown on the display when the knob is turned. The function of each knob is displayed here. Compressor Mode The Compressor Mode provides settings for the Compressor, Noise Gate, and Blend Level for the effect loop. To enter the Compressor Mode, press and hold the [FUNCTION] switch until the knob functions are displayed in the upper row of the panel display above the knobs (the row above that used by the Equalizer Mode). ● How Knobs Function in the Compressor Mode The knob's value is shown on the display when the knob is turned. The function of each knob is displayed here. q w e r t y u i o !0 !1 q INPUT LEVEL: Sets the Input Level w SOUND TYPE: No function. e COMP (PEQ F): Sets the center frequency of the 1-band parametric equal- izer (20Hz to 20.0kHz, 255 steps) r GAIN (PEQ Q): Sets the bandwidth of the 1-band parametric equalizer. (0.1 to 20.0, 255 steps) t MASTER (PEQ G): Sets the gain level of the 1-band parametric equal- izer. (-15dB to +15dB, 0.2dB step) y BASS (FREQ): Sets the center frequency of the BASS control knob. (20Hz to 320Hz, 255 steps) u LOW MID (FREQ): Sets the center frequency of the LOW MID control knob. (80Hz to 1.28kHz, 255 steps) i MIDDLE (FREQ): Sets the center frequency of the MIDDLE control knob. (250Hz to 4.00kHz, 255 steps) o HIGH MID (FREQ): Sets center frequency of the HIGH MID control knob. (500Hz to 8.00kHz, 255 steps) !0 TREBLE (FREQ): Sets the center/cutoff frequency of the TREBLE con- trol knob. (1.25kHz to 20.0kHz, 255 steps) !1 OUTPUT: Sets the output level Gain t PEQ G + r PEQ Q 0.1 20 0 - e PEQ F Frequency q w e r t y u i o !0 !1 q INPUT LEVEL: Sets the Input Level w SOUND TYPE: No function. e COMP (RATIO): Compression ratio (1.0 - ∞, 16 steps) *operates the same as COMP in the Amp Mode. r GAIN (THRSLD): Compressor threshold level (-54dB to 0dB, 1dB step) Sets the signal level from which the compressor will activate. Compression is applied to signals that exceed this level. t MASTER (ATTACK): Compressor attack time (0msec to 120msec, 1msec step). Sets the amount of time required for application of the compressor from the time the signal exceeds the threshold. When a slow attack time is set, the beginning of the attack will not be compressed. y BASS (RELEASE): Compressor release time (5msec to 42.3 sec, 160 steps). Sets the amount of time required for the compressor to switch off after the signal goes below the threshold level. This smoothes gain changes to keep the sound natural. u LOW MID (C. GAIN): Compressor gain (0dB to 18dB, 0.1dB step) This parameter works in conjunction with the compressor ratio setting which is set with the e COMP (RATIO) control knob. In other words, gain is automatically adjusted along with amount of compression applied to the signal. If the Ratio = "1.0", Gain = "0". If the Ratio = "∞", Gain = the setting determined with the control knob. i MIDDLE (KNEE): Compressor knee (Hd (Hard), 1, 2, 3, 4, 5) Sets the depth of signal compression after the input signal exceeds the threshold level. When set to Hd (hard), compression starts soon with the ratio you have set. However, when set to 1-5, compression startup is gradual, creating a more natural sound (soft knee compression). o HIGH MID (N. GATE): Noise gate threshold level (OFF, -53dB to 0dB, 1dB step) When the input signal's level falls below this set level, the noise gate activates cutting off the signal. !0 TREBLE (BLEND): Blend level between the effect loop's RETURN signal and the dry signal (the sound created in the BBT500) (0% (Return 0%, Dry 100%) to 100% (Return 100%, Dry 0%)). !1 OUTPUT: Sets the output level 14
