BV120H
All Tube Guitar Amplifier
The Front Panel:
1. POWER: This switch applies AC volt-
age to the amplifier, and should always be
turned on first. The switch illuminates
when the AC power is on.
2. STANDBY: This switch activates the
amplifier, and should always be turned on
last. The switch illuminates when the high
voltage power is passing through to the
tubes.
NOTE: When you first power up this
amplifier, leave the Standby switch
OFF for at least 20 seconds. This
gives the power tubes a chance to
prepare themselves for action.
3. PRESENCE: Increase the level of
upper harmonics with this control. The
presence control allows a boost of up to
5dB at 10kHz.
4. EFFECTS LOOP PAD: This switch
activates a 12dB pad on the effects send
signal and corresponding gain recovery
on the return. In the out position the signal
is full strength which is best suited for line
level rack mountable effects. With the
switch depressed the signal is lower which
is best suited for foot pedal type effects.
5. EFFECTS LOOP SWITCH: This switch
controls the effects return signal of the
effects loop. The loop is only active when
the switch is pressed in. When a
footswitch is used, this switch is disabled.
The adjacent yellow LED illuminates when
the loop is in use.
6,7. REVERB 2, REVERB 1: Adjust the
amount of reverberation on each channel
with these controls: at the "0" position the
signal is "dry" (no reverb). As you rotate
the control clockwise, the amount of
reverb increases.
Channel 2:
8. LEVEL: Set the output signal level of
channel 2 with this control. At the "0" posi-
tion (full left) very little or no signal will be
heard; as you rotate the control clockwise
(towards center) the output level of chan-
nel 2 increases. Use this control along
with your guitar's volume and the channel
2 gain control (#12) to produce a wide
variety of sounds.
9. BASS: Adjust the bottom end response
with this control. The low control covers a
range of 15dB at 100Hz. This sets the
amount of bass heard (and felt) from the
amp.
10. MID: Adjust the midrange response
with this control. The mid control covers a
range of 13dB at 500Hz. This controls the
“voice” of your guitar.
11. TREBLE: Adjust the high end
response with this control. The high con-
trol covers a range of 10dB at 10kHz. This
controls the “bite” of your guitar.
12. GAIN: Adjust the overdrive (distortion)
level with this control. With the control
towards “0” (to the left) the signal is rela-
tively clean. As you rotate the control
clockwise the distortion increases, along
with the overall output level. Rotate the
control towards “10” and you’ll increase
the distortion even more.
13. CHANNEL SELECT: Switch between
channels with this push-button switch. The
adjacent amber LED illuminates when
channel 1 is selected (switch in the out
position), the red LED illuminates when
channel 2 is selected (switch depressed).
When a footswitch is used for channel
switching, this switch is disabled.
Channel 1:
14. BASS: Adjust the bottom end re-
sponse with this control. The low control
covers a range of 16dB at 100Hz. This
sets the amount of bass heard (and felt)
from the amp.
15. MID: Adjust the midrange response
with this control. The mid control covers a
range of 20dB at 300Hz. This controls the
“voice” of your guitar.
16. TREBLE: Adjust the high end
response with this control. The high con-
trol covers a range of 10dB at 10kHz. This
controls the “bite” of your guitar.
17. LEVEL: Set the output volume level of
channel 1 with this control.
18. INPUT: Connect your guitar or wire-
less receiver into this standard 1/4" jack by
means of a shielded instrument cable.
