9.3 Changing the Jumper Settings – Multiset
The Multiset has internal jumpers, which allow to change input sensi-
tivity and output level per channel. More information on these settings
can be found in chapter 8.5 and 8.6.
❐
Please note that those jumpers are not meant to be changed every day.
They should be changed when the unit is operated for the first time, so that
it matches the Studio's operating level. Only change them if it is really nec-
cessary. The factory d4 dBu will in most cases offer perfect results.
To change the jumper settings the Multiset must be opened. Consult
an experienced technician if you are unsure of how to do this. Please
follow the instructions below.
1. Remove all jacks and cables from the Multiset.
2. Loosen and remove both screws of the ADAT Sync D-sub socket.
3. Use a screwdriver (Phillips 1) to remove the 6 screws on the cover of the
Multiset, so that the cover can be taken off.
4. Place the device with the front panel in front of you. Lift the cover at the
front by about one centimeter (0.5 inches). Then pull the cover slowly
about 2 centimeters (1 inch) towards you. When doing so the TRS jacks
and the D-Sub socket will slide out of the rear panel. The cover is now not
attached to the rest of the housing and can be turned to the right.
Use this unique moment and have a look at the internal design of the Multiset.
On the right side of the lower printed circuit board (PCB) you can see the two
switching power supplies. They generate both 5 Volts (for the digital circuitry)
and ±13 Volts (for the analog circuitry) from nearly every possible input volt-
age. In the center you'll see the heart of the Multiset, the Xilinx FPGA. The ana-
log circuitry and DA-converter for the headphone output is located on the right
of the FPGA. Left of the FPGA two Low Jitter PLLs can be seen. On the outer left
side you'll find 16 capacitors of the analog outputs and a 50-pin flat cable con-
nector. The flat cable connects lower and upper board, the latter being the an-
alog board, which is mounted on the inside of the cover.
The analog board is covered by a thin metalized shield, preventing noise from
digital circuitry and flat cable being coupled into analog inputs and outputs.
Lift the shielding and take a look at the analog board.
