Crate Amplifiers BV-50H Musical Instrument Amplifier User Manual


 
Introduction:
The BV-50H is a feature-packed professional stage performers' amplifier. Rugged construction, reliable
American craftsmanship and two powerful channels of pure tube power are some of the trademarks of this
new and impressive piece of musician's equipment. This amplifier features two distinctly different 12AX7
tube-driven channels: one with classic tube rhythm sounds and one offering you some of the finest lead
and overdrive sounds of any stock amplifier.
Each channel features an all-tube preamp section with three bands of equalization for total tone con-
trol. The master Presence control lets you custom tailor the sound of your guitar to suit your particular
needs.
The Line Out signal is tapped directly from the speaker outputs, then attenuated and frequency-compen-
sated to replicate the sound of a miked speaker cabinet. Two pairs of speaker output jacks provide easy
impedance matching with a wide variety of cabinet configurations.
Features:
Here's a quick overview of the BV-50H's features and controls. Additional information can be
found on the pages indicated.
• Patented Channel Switching Circuitry: Achieves maximum use of each preamp tube - so unique
it's patented!
• Adjustable Presence Control: Fully adjustable upper harmonics level for changing the "presence"
of both channels (page 4).
• Auto-Biasing Circuitry: Want to change your sound? Change your tubes! Internal circuitry allows
the use of either 6L6 or EL34 power tubes with no bias adjusting (page 7).
• D.C. filament supply for first stage: eliminates the need for a “hum balance” control.
• Effects Loop: For noiseless patching of external effects, or use as a preamp out/power amp in con-
nection (page 5).
• Line Out Jack: Taken directly from the speaker output signal! This frequency compensated output
lets you patch into house sound boards, recording consoles, etc. with ultimate sonic fidelity (page
5).
• Footswitch Jack: This stereo jack - (tip for channel selection and ring for reverb on/off control) -
allows use of a two-button footswitch (page 5).
• Speaker Jacks: Impedance-matched speaker connectors allows at least four different cabinet con-
figurations (page 5).
• High Cosmetic Appeal and Stage Presence: The unique cosmetics of the BV-50H serve as a trib-
ute to your good taste in musical equipment.
