Setting Amplifier ID
Use the Function button to choose Amp ID. Each Amp ID is composed of two,
two-digit hexadecimal values (see Appendix C for more information on Hex
Numbering).The upper two digits (the High Value) and the lower two digits (the
Low Value) can be independently adjusted. For this function, the Select button
toggles between these two values.
Select a value for adjustment, and press Edit. The selected portion of the ID will
flash, and the increment and decrement keys can now be used to adjust the value.
An amplifier’s I.P.Address can be used to designate an amp in a network, however
Amp ID is more useful for designation, particularly when DHCP is being used.
Note: For instructions on I.P.Addresses, designing and setting up a
complete network, please see Appendix C:

Amplifier IDs can remain fixed even if I.P.Address change, making the amplifier’s
settings and operating conditions easier to track. Additionally, creative use of the
High and Low Values in the Amp ID can provide even more information about an
amplifier. Since the two values can be adjusted independently, the High Value could
be used to designate a group of amplifiers, while the Low Value would identify
specific amplifiers in that group.
Adjusting Gain
Use the Function button to choose Gain. In this mode, the Select button chooses
between Channel 1 thru 8. With the proper channel selected, press the Edit
button. The increment and decrement buttons will now adjust the channel’s gain.
If the channel has been muted by NexSys, the first press of either the increment
or decrement will bring the channel out of mute and return its previous value.
Subsequent presses will adjust the gain value. Once the gain has been adjusted,
pressing the “Edit” button again will lock in the value and the display will stop
flashing. Gain values are listed in dB, from 0 (unity) to –80. The setting of the
amplifier’s attenuators will also affect the overall gain. The attenuators are positioned
after the NexSys gain control in the amp’s gain structure resulting in an additive
attenuation value. For example, if an attenuator is set to –6dB, and the NexSys gain
for that channel is set to –10dB, the amplifier’s overall gain will be 16dB below the
amplifier’s maximum output.
Condition Monitoring
These functions do not make use of the Edit and increment/decrement buttons.
They simply provide information concerning the amplifier’s operating condition.
Temperature
Use the Function button to choose Temperature.The internal ambient temperature
of the amplifier will be displayed with a designation of “F” for degrees Fahrenheit
or “C” for degrees Celsius.To change the units that the temperature is displayed in,
press the Select button.
