Amplifier IDs can remain fixed even if the I.P.Address changes,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 val-
ues can be adjusted independently,the High Value could be used to des-
ignate 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 A and B.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” but-
ton 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
ouput.
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.
AC Line Voltage
Use the Function button to choose AC Voltage. The AC line voltage will
be displayed.
