4 BV150H Three Channel Guitar Amplifier The Front Panel – Channel 3: 16. CH. 3 SELECT SWITCH:This switch, when activated, selects Channel 3. The red LED above the switch illuminates when Channel 3 is selected. When the footswitch (#28, rear panel) is connected, either the front panel select switches orthe footswitch may be used to select the active channel. 17. GAIN:Use this control to adjust the input gain for Channel 3. With the control rotated counter clockwise, the resulting tones have a puchy tube sound (perfect for agressive rhythm guitar). As you rotate the control clockwise the tones take on serious overdrive dis- tortion. 18. TREBLE:Use this control to adjust the high frequency output of Channel 3. The Channel 3 Treble control provides 15dB of boost or cut at the frequency selected by the High Freq Select switch (#19). 19. HIGH FREQ SELECT:Use this rotary switch to select the fre- quency for the High control (#18): 2kHz, 4kHz, 6kH, 8kHz or 10kHz. 20. MID:Use this control to adjust the mid frequency output of Channel 3. The Channel 3 Mid control provides 20dB of boost or cut at 1.2kHz. 21. LEVEL:Use this control to adjust the output level for Channel 3. Use this control in conjunction with the Channel 3 Gain control (#17) to achieve the desired sound for Channel 3. 22. BASS:Use this control to adjust the low frequency output of Channel 3. The Channel 3 Bass control provides 18dB of boost or cut at at 100Hz. Effects Loop, Eek! and Ugh!: 23. LOOP SWITCH:This switch, when activated, engages the rear panel Effects Loop (#33–37, rear panel). Ths blue LED above the switch illuminates when the rear panel effects loop is engaged. When the footswitch (#28, rear panel) is connected, either the front panel Loop switch orthe footswitch may be used to engage the effects loop. Note:This may also be used as an additional Boost switch – see #37, page 5 for detailed information. 24: EEK!:Use this high frequency power amp damping control to add definition and more of an edge to your sound. The Eek! control is useful for compensating for acousticlly absorbent rooms or cabi- nets with overbearing low frequency resonance. 25: UGH!:Use this low frequency power amp damping control to add control and shape the low end of your sound. The Ugh! control tightens the low frequencies when rotated counter clockwise, giving better control over the speaker cones. When this control is rotated clockwise, the speaker cones are allowed to move more freely which gives the sound more thump. 26: STANDBY SWITCH:Use this switch to activate the amplifier (top of the switch depressed) or place the amplifier in the stand by mode (bottom of the switch depressed). The amplifier should be in the stand by mode during set breaks. This switch illuminates when the amplifier is active. Note:The Power switch (#27) must be turned on for at least ONE MINUTE before turning on the Standby switch. 27. POWER SWITCH:Use this switch to turn the amplifier on (top of the switch depressed) and off. This switch illuminates when the amplifier is turned on. 2222 2020 1818 1616 2121 1919 1717 2727 2626 2525 2424 2323

5 BV150H Three Channel Guitar Amplifier The Rear Panel: 28. FOOTSWITCH JACK:Use this jack to connect the BVFS4 four- button footswitch to the amplifier for remote control of channel selec- tion and effects loop on/off. Use the supplied MIDI cable for this con- nection. (A five-wire MIDI cable mustbe used for proper operation of the footswitch.) 29. SPEAKER OUTPUT JACKS:Use these jacks to connect the amplifier to your speaker cabient(s) by means of heavy duty (16GA minimum) speaker cables. Note:NEVER use the amplifier if it is not connected to a speaker cabinet! 30. IMPEDANCE SWITCH:Use this switch to match the amplifier impedance to match your speaker cabinet(s). Use the following chart and be certain this switch is at the proper setting before turning on the amplifier: IMPEDANCE NUMBER OF TOTALOF CABINETS CABINETS IMPEDANCE 16 ohms 2 8 ohms 16 ohms 4 4 ohms 8 ohms 2 4 ohms 31. SLAVE OUT JACK:Use this jack to conenct the amplifier to a second guitar amplifier, a powered monitor, or recording console. The signal at this jack is an attenuated replica of the signal at the Speaker Output jacks (#29). Note: The Slave Out Level control (#32) must be fully counter clock- wise before connection is made from the Slave Out jack to another piece of equipment! SLOWLY rotate the Slave Out Level control clockwise when setting the slave equipment levels. 32. SLAVE OUT LEVEL:Use this control to adjust the output level of the signal at the Slave Out jack (#31). 33. EFFECTS LOOP SEND LEVEL:Use this control to adjust the level of the signal at the Effects Loop Send jack (#34). 34. EFFECTS LOOP SEND:Use this jack to send a line level signal to the input of an external effects processor.35. EFFECTS LOOP SERIES/PARALLEL SWITCH:Use this switch to configure the Effects Loop for series or parallel operation. Experimenting with various effects will determine which setting pro- vides the best results. 36. EFFECT LOOP RETURN JACK:Use this jack to return the sig- nal from the output of an external effects processor into the effects loop. 37. EFFECTS LOOP RETURN JACK:Use this control to adjust the input level of the signal at the Effects Loop return jack (#36). NOTE: The Effects Loop can also be used as a gain boost: con- nect a signal cable between the Send and Return jacks and use the Effects Loop Send and Return Level controls (#33, 37) to adjust the amount of signal boost - up to 6dB in series mode and up to 9dB in parallel mode. 38. HUM BALANCE:Use this control to minimize the residual hum in the amplifier. Use a small flatbalde screwdriver to gently rotate the control until the hum is at a minimum. Allow the unit to fully warm up and set all Level and Gain controls fully counterclockwise before adjusting this control. 39. FUSE:The fuse protects the amplifier from voltage overload con- ditions. If the fuse fails, replace it onlywith the same size and type of fuse. If the fuse fails repeatedly contact your Crate Service Center. 40. AC INLET JACK: Insert the female end of the power cord firmly into this jack. The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power and frequency require- ments stated on the rear panel. Do not attempt to defeat the safety ground connection! 2828 2929 3030 3131 3232 3333 3434 3535 3636 3737 3838 3939 4040 The BVFS4 footswitch – select channels and turn the effects loop on and off with just a tap of your foot!
