  • Page 4: Installation

    - The appliance should not be operated near any water or in a location where moisture might be present. - Always connect the mains earth to the unit. If the 1970 is to be continuously moved from one location to another, we suggest using additional support in the rack at the rear of the unit. POWER CONNECTION The unit will have been supplied with a power cable suitable for domestic power outlets in your country.

    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 1970 fully conforms to the EMC standards, if the unit is used where it maybe exposed to high levels of disturbance such as found close to a TV or radio transmitter we suggest that the screen of the signal cable is connected to the chassis connection on the XLR type connector.

  • Page 8 With the link switch off the Mix, Gain and Bypass controls of the two channels are independent of each other, this allows for the 1970 to be used to track two independent signals, but also allows for unbalanced stereo signals to be adjusted should image shifting occur during compression.
  • Page 9: Hints And Tips

    Another widely used technique especially when recording bass guitar, is to record one channel via a mic’d cabinet, and the other directly into the instrument input on the 1970, or via effects using the line input, and blend the two signals at a later stage.
