Differential Outputs
Switch
The Differential Outputs switch has two actions. In normal mode, it
separates between the two channels so each channel can be used
separately. In Differential Mode, this switch disables channel 2
inputs and converts the internal circuits to output differential
signals. Channel 1 is used for outputting the normal output and
channel 2 is used for outputting the inverted signal. When this
switch is depressed, the front panel led illuminates, designating that
the differential mode has been selected.
Grounding
Considerations
Understanding how to connect your ground path could be critical to
preserving the integrity of your output signal. If you are using a
single-ended output then it will probably be safe for you to connect
the circuit ground to case ground. Always bear in mind the following
warning:
WARNING
Input and output grounds are tied together to case
ground and therefore, it is absolutely forbidden to
connect the output ground to a different level than
the input ground. Failure to adhere to this
limitation may damage the 9260 and the
surrounding equipment connected to its I/O
connectors.
Operating
Instructions
Being a passive device, there are no controls, nor computer
programming required to operate the Model 9260. The following
procedure is recommended for proper operation of the power
amplifier:
1. Make sure your box is configured for input and output
impedance and gain
2. Follow the installation instructions given in Chapter 2 of this
manual
3. Connect the output terminal to your load
4. Connect the input terminal to your source
5. Turn on power to your 9260
WARNING
There is no switch control to turn 9260
amplification on and off and therefore, the
amplifier is active immediately after you power it
up. Always make sure your load is protected from
inadvertent power up conditions before you turn
on your 9260.
