Introduction This kit makes it easy to interconnect a Neve 51 Series preamp and equaliser module for rack mounting. It also allows you to connect the inputs, outputs and power supply needed to use the unit, reducing the amount of wiring required to a minimum. The power bus system allows you to connect up to 8 modules, i.e.
Kit overview An input interface card for connecting: § A preamp / dynamics module. § Mic and line inputs. § DI input (optional). § LED meter (optional). § Signal meter threshold bus. § Power bus, compressor/gate link. An EQ interface card for connecting: §...
Conventions Component layout Vertical layout of diodes Straps are made using component legs. The Molex KK connector tab is located on the edge of the board. Location Pin 1 of the Molex KK connectors is on the left. Pin 1 of the IDC connectors is marked with a triangle. Wiring IDC connectors Only IDC connectors are supplied with the kit.

Making the connection cables The PSU ribbon connects the 51/V PSU power supply to the Input interface card. This ribbon also carries the dynamics chain loop when several preamps are connected. Once the components have been positioned in the rack, you need to measure the length required to connect the cards and the power supply, then cut a ribbon to the required length.
Linking dynamics 2 jumpers are used to define the position of the module in the chain 2 straps will be placed in JP1 and JP2 facing the position number in the chain To chain 4 Dynamics : Il faut couper les brins 15 et 16 du ruban BUS PSU aux endroits indiqués Labo ★...
Assembling elements For greater clarity, the Input and EQ interfaces are laid out flat on the diagrams. It is of course possible to arrange these cards vertically, in which case the length of the ribbons will have to be adapted accordingly.

Modification of board 10880 of eq Neve 51 The Patch interface 10882 card on the equalizer module must be removed. A jumper must be fitted between pins 2 & 3 and 1 & 9 of FSP7. Labo ★ K Effects – www.labo-k-effects.com – karim@labo-k-effecs.com...
Verification It is good practice to test the interface cards before connecting the modules. Start by testing the power connections before powering up. Use a beeper to check that the supply voltage rails arrive at the correct points. Start with the Input card alone. The 0V should arrive at pin 10 of the CONN3 Molex connector.
Settings and adjustments To make the following settings, the following conditions must be met. Audio input will be via the LINE input. Set the gain trimmer to 0. Check that the filters, equaliser and Dynamics are not engaged. Apply a sinusoidal signal of frequency 1khz and amplitude 0dBm to the line input of the input module.
