Kits of input and output select control module by pass multi-purpose use of installed capacity author of the report: tris Translation: Google

Recently-User equipment to remove A2 (Dx) home, I asked Will to help him with a JP200, there have also just before the JP200 dx package, but the missing vacuum tube, he has to buy me Even if the assembly can help it-equipment, thought he put every other day sent from the vacuum tube, but there is a demand for dx JP200 BY PASS need to provide the audio amplifier theatres around the main channel through sharing of A2 and JP200 BYPASS Speakers, then think of this BEN large choice of two-channel input and output packages have independent control of two built-in output due What to do, is the largest telephone Taojiao BEN, the BEN done a great guiding the following modifications:

Kits of input and output select control module Schematic.


　

Changes:

1. As to the choice of output is less than pre out of the (NO INCLUDE) so the component parts not to, C2 C6, C3 C7 deal with negative short-circuit

2. The original signal output by L5-L6 to co5 control of the two independent output L7 (out1) L8 (out2) to the RCA video output signal, is to reverse processing, signal sent by the L5 from the control of two independent co5 Output L7 (out1) L8 (out2) done by pass switch, and then from L6 output signal to the chassis RCA video output, so L5 L6 maintain disconnect, J1 J2 J3 not received, at the same time to avoid voice Shimoji will be installed on pcb L7 L8 Two relay off on both sides of the holes (photo upper left) will do reaming relay at the same time deal with the two-pin cutting.

3. Map by pass from pcb back directly to the L5 signal line pulled L7 (out1) for the importation of reverse

4. JP200 combination with another from L5 positive signal line terminal blocks access to the chassis volume VR JP200 pcb on the RL to enter from the output (photo middle blue terminal) cable to the black gold output to the plate L8 (out2)

5. Also as a result of retrofitting delay output signal from the alignment L6 into the delay to output RL IN RL out again received a chassis-RCA output

6. Output of the electricity supply to the choice is to use the large double-Ben silicon steel enclosures EI transformer, while output from the pin pulled out C9 plus or minus dc 5V supply delaying the use of output, but also save templates on the extension of the three components of the regulator

7. As a result of ARC Class chassis backplane wind holes and the Black Gold input and output choices for the ride, if changes are not enter the four groups of two independent output one-on-one Qiaqia Hao, L6 change output after a group of RCA Output Parallel the February 2

8. Panels to front-band switch-home wiring CO4 four groups enter the middle Alice blue plate switch to the power switch right switch plate Alice CO5 wiring to do BY PASS switch. Chassis do not have all the other openings are no extra holes (with the exception of The back four XLR)

9. Connect 300 B-examination by the panel the right switch plate Alice Zuoshang襏by passCD straight-or under-enter the former襏jp200 preview comparison,……. Switch easily,. Chaohao Yong of the black gold output to choose, machinery RUN After a two-hour JP200 voice is more open, although water-feeding did not make any changes without phbbbbt no noise, background quiet, and then Run a few days to organize the body line, can a perfunctory

10. This black gold output with input BEN only bought a large PCB board, the original package terminal can be used are black gold fever Oh terminal

11. This is the largest of the BEN, the thank you but to remind any kind hyacinth Xiongtai according to amend the problem, then please look for BEN, over the great responsibility by Ben, Ha ha
