Bugera BVP5500

<em><strong>On 13/09/2009:</strong>
</em>
Hybrid prampli head lamp 2 x 12AX7 + 2 x 550W MOSFET amplifier 12AX7B + 4 Ohms.
9-band graphic equalizer with its output level between prampli and the amp.

<strong>Orders faade:
</strong> <em>
Section prampli lamp:</em>

Button light switch in between attnuateur-15dB bass active. Light button "Bright" +6 dB @ 3kHz.
Light button "Ultra High" +6 dB @ 5kHz. Light button "Ultra Low" Cumulative Effects 2.5 dB @ 50Hz and-12dB @ 560 Hz @ 5 kHz and 1.5.

Potentiomtre GAIN indicating crtage section prampli Ignition Button LED attnuateur if not in use (if attnuateur Lumire permanent service, shame there is not a dual LED -color for crtage).
The monitors crtage dtecteur of 4 points of the Schematic (derrire tubes) and reflects the correction of rglages prampli: BASS / MID / TREBLE + + ULTRA ULTRA HIGH LOW BRIGHT +.

Potentiomtre BASS +-12dB @ 50 Hz
Potentiomtre MID-15dB to + values ​​slecteur just ct: 220Hz, 450Hz, 800Hz, 1.6 kHz and 3kHz.
TREBLE-14 Potentiomtre 19dB @ 5kHz. MAIN Potentiomtre level for injection into the MOSFET power amp.

GAIN VALVE Potentiomtre that changes the voltage on the plates of the tubes of prampli (background = normal diet, clear, linear, minimum = saturharmoniques and compress by non linares tubes under food).

Warning: the change in voltage when it varies trsdoucement "down" zero-button, gently as your speed of rotation of potentiomtre because the filter capacitor voltage of Feeding tubes are long to offload it&#39;s normal. The effect corresponds to the change in the slope of the gain of the tubes: lgrement compress avecdistorsion harmonic "soft".

MUTE button.
<em>Section qualiseur APRS tubes, Integrated Circuits:
</em>
On / off switch qualiseur.

10 potentiomtres of linear qualiseur (9 + 1 frquences gain level).
Frquences: 33Hz / +-15dB, 80/150/300/600/900/2000 / +-8dB, 5kHz / +-9dB, 8kHz / +-10dB.
Level Gain: +-10dB.

<em>At the rear:</em>
Loop + insertion effects loop sparation Prampli / amp.
Line Out symtrique / asymtrique potentiomtre small adjustable, with PRE / POST button before or transplanted to the APRS prampli effects loop and a + button to set the mass of the chassis or not XLR.
Output to tuning indicator.
PDAL two buttons: "MUTE" to squelch, and M / A qualiseur (not blocking orders faade).
All connectors 6.35 mm mono jack, except PDAL Stereo jack 6.35 mm and XLR line out 3. Output HP: 2 mono jacks and a 6.35 in SPEAKON parallle.
<em>Comment:</em>
The layout of the controls and the faade Schematic of principle like the AMPEG SVT 3 PRO, less a fifth lamp type 12AU7 that attacks in the power amp AMPEG.

UTILIZATION

Easy to use, almost instinctive, the sound is easily modeled.
It is possible, thanks the pedals, using the qualiseur (gnral and level adjustable) for a solo.
Manuel succinct but sufficient (compare that of AMPEG).

SOUNDS

I possde low "exotic" pramplifie the sound clear enough that allows me a variety of "colors" via this excellent report qualitprix extra head!

OVERALL OPINION

I have only a few days, we will use.
The price is excellent for beginners and amateur snior occasional trs I am.
I dj jet an eye on the quality of its manufacture in-house: trs correct, nothing trane.
I have pictures for the curious ...
All this explains my total satisfaction and grades indicated.
<em><strong>Subsequently, 26 October 2009:

I now have a cabinet Hartke 4200 Pro and connect sounds impeccable!

I just changed the sources ampliBugera because I use high level BF and when it activates the attnuateur between the prampli, the LED on the button that indicates the rc Tage is lit continuously to indicate the activity in attnuateur. I was sad not to have an indication light to the gain of rgler prampli!

So I modified the circuit board and added an LED for a deuxime boutoncouleur green (instead of red) setting the attnuateur serviced and continue to have the indication of the pulse of crtage couleurrouge.

<em><strong>It works, and I am proud to have the only Bugera 5500 BVP in the world with a button and two-tone forthe fonctionattnuateur crtage (still in use)

Button turns amber, and crtage attnuateur switched current (red + green = Amber):

By the way, I disassemble the compltement DGIG faade and the main PCB. Trs components are correct, although the circuit liberalization and the excellent patent protection. L, too, have some pictures as evidence for the curious

In fact, LEDs 3mm yellow / orange are the supports of the lamps (in the small hole in the middle of the support) and are to give the pretty color "flame" at the bottom of the tubes, visible through the cracks amnages in the top panel. Trs nice effect, attracted me because I was the oeuil Lumire the curious ...
