The 1968 MkII is designed for standard 19" rack mounting

and occupies 1U of rack space. Avoid mounting the unit

directly above power amplifiers or power supplies that

radiate significant amounts of heat and always connect

the mains earth to the unit. Fibre or plastic washers may

The inputs and outputs are electronically balanced on conventionally wired XLRs (pin 1 screen, pin 2 hot, pin 3 cold and

XLR shell is connected to chassis). The operating level is nominally +4dBu. Balanced use is recommended.

• Interference:

If the unit is to be used where it maybe exposed to

high levels of disturbance such as found close to a TV

or radio transmitter, we advise that the unit is oper-

ated in a balanced configuration. The screens of the

signal cables should be connected to the chassis con-

nection on the XLR connector as opposed to connect-

ing to pin1. The 1968 MkII conforms to the EMC stand-

ards.

The side chain feature on the 1968 MkII is part of the compressor feedback stage and would normally be connected to

a normalised or semi-normalised pair of patchbay contacts. This would allow the user to insert additional EQ for some

de-essing, or frequency conscious compression. The side-chain access point is unbalanced, connection is via stereo

1/4" jacks, the wiring convention being: ring is signal send, tip is signal return and sleeve ground.

be used to prevent the front panel becoming marked by

the mounting bolts. Because the tube circuitry generates

more heat than an equivalent solid-state design, it is

advisable to leave space above the unit to allow the heat to

dissipate.

• Ground Loops:

If ground loop problems are encountered, never dis-

connect the mains earth, but instead, try disconnect-

ing the signal screen on one end of each of the cables

connecting the outputs of the 1968 MkII to the

patchbay. If such measures are necessary, balanced

operation is recommended.
