Gemini DJ PA-7000
This is a usable analog preamplifier HiFi (after a few improvements).

UTILIZATION

Simple manual, obvious connections

SOUND QUALITY

No staining but various noises (bad bad power transformer and filtered)

It can be improved very easily, in which case it becomes great:
- Change the voltage by an impregnated model (planar transformer primary side 2 x 115 V 2 x 18 V 18 VA Spitznagel SPF SPF 1,831,818 1,831,818).
mount the transformer on small foam pads
- Change the filter capacitors by 600 μf/50v.
- Replace the original op amps by NE5532P (4)
- Thoroughly check all welds of the device (it's made in China).

total cost of changes: 25 euros with shipping!
The sound becomes perfect: more noise, more breath and RIAA entry worthy of the name

OVERALL OPINION

very good buy if small modifications, simple but thorough is performed
The next step in customization will be the replacement of all chemicals and other knobs and switches capacitors,

I use to pre-amp for 2 years he can use my sound system as string Hi-Fi easily.
It possde input anx 4, cd, tuner, phono, input / output for a recorder or other platinum K7, there is also a microphone input mixable. SETTING THE The volume is large but not too prcis beyond mid power.

UTILIZATION

Full record
used as a hi-fi amp btte
between mic for karaoke

SOUND QUALITY

The 3-band equalizer is handled with dousseur because it is a little too straight forward as I got lonrdenss function. The function is handy kut low for vinyl. The amp RIAA is correct and does not stain like the pre-amp gnral.

OVERALL OPINION

_ Tranfo vibrates and makes some noise
_ Equalizer lourdenss tops and nag
_manque one or two supplmentaires input (TV, VCR ...)
Positives:
_ Unique product in this price range
_ 2 RCA 1 XLR
_ Trs quality sound right no breath and no audible distortion
