REAR PANEL DESCRIPTION
1. INPUT CONNECTORS.
An active balanced input ultilizing a combo connector
compatible with either a 3-pin (XLR-type) or a ¼" TRS plug. Polarity follows the
AES/ANSI/IEC standard of pin 2 (tip) positive, pin 3 (ring) negative and pin 1
(sleeve) signal ground.
2. INPUT TRIM SWITCH.
In its
+4dBu
position, the input gain is unity. In the
–
10dBV
position, the input gain is increased by 12dB (although mathematically
suspicious, it really is 12dB, not 14dB). This compensates for so-called “semi-pro”
(which I guess means you sorta get paid) recording equipment. THE FRONT
PANEL CALIBRATION MARKS ASSUME THIS SWITCH IS IN THE
+4dBu
POSITION. The only exception to this is the Output Meter Mode marks which
remain accurate in either position.
3. OUTPUT CONNECTORS.
These connectors follow the polarity convention
outlined above. Wired in parallel, both connectors may be used simultaneously, if
needed.
4. GROUND LIFT SWITCH.
In its
LIFT
position, signal ground and chassis ground
are not connected.
5. REMOTE POWER SUPPLY INPUT.
This unit is supplied from the factory with a
Model RS 1 Remote Power Supply suitable for connection to this input jack. This
unit’s power requirements call for an 18 volt AC center-tapped transformer only.
THIS IS NOT A DC INPUT. IT IS NOT A TELEPHONE JACK. NEVER USE A
POWER SUPPLY OTHER THAN THE ONE SUPPLIED OR AN EXACT REPLACE-
MENT OBTAINED FROM RANE CORPORATION.
Using any other type of supply
may damage the unit and void the warranty.
6. CHASSIS GROUND POINT.
A 6-32 screw is used for chassis grounding purposes.
See
CHASSIS GROUNDING
note on last page for details.
