APPENDIX—PROGRAMMABLE FEATURES
The following listing are ESP
®
-2 features that can be programmed or
accessed by your installer to customize or troubleshoot your system.
Factory default settings are shown in bold.
NOTE: The Bitwriter® must have software version 2.7 or above to
access the amplifier features menu.
NOTE: A setting marked “Reserved” is for future development. Some
settings are read-only, i.e. they cannot be changed, only viewed. If
changed, the bitwriter will fail verification of the parameters upon
write and indicate an error.
Turn On Delay - 1.5, 2.0, 2.5, 3.0, 3.5, 4.0 seconds. Delays the amplifier
turn-on when the head or source unit is turned on. This eliminates any
annoying pops or noise during power up from the head or source unit
from feeding through to the amplifier.
ESP®-2 Status Indicator LED Mode
Off Amplifier Off
5 short flashes, pause, then repeats Unit powering up
Solid Illumination Normal Operation
1 long flash, pause, then repeats Overvoltage
1 short flash, pause, then repeats Undervoltage
2 short flashes, pause, then repeats Overcurrent
3 short flashes, pause, then repeats Thermal protection
4 short flashes, pause, then repeats DC offset
Input Gain Range (Volts) - The position of the gain switch determines
the gain range available. If the gain switch is in the high mode, the
ranges are Default (0.2 - 4V), 0.2-1V, 1-1.5V,1.5 - 3.5V, 3.5-4V. If the
gain switch is in the low mode, the ranges are Default (0.4 - 8V), 0.4 -
2V, 2 -3V, 3V - 7V, 7-8V.
NOTE: If the Input Gain Adjustment is set to Lock (see below), the
Input Gain Range adjustment will not be altered until the Input Gain
Adjustment is set to Unlock.
Input Gain Adjustment -Unlock, Lock. When set to “Lock”, the input
gain adjustment is disabled. This can be set to lock after the amplifier
has been installed and set up to prevent accidental or unwarranted
adjustment.
NOTE: Use caution when adjusting or unlocking gain as restricting
the range or unlocking the range can result in sudden increases in
gain. We recommend turning down the source to avoid damage to
speakers and/or your hearing prior to exiting this mode.
Event 1 through 7 - Stores up to seven recent events that have
occurred to aid in diagnostic troubleshooting. The events that are
retained are: Undervoltage, Overvoltage, Reserved, No Fault, Thermal,
Overcurrent. These events are read-only, the amplifier will not allow
them to change, even if they are changed on the bitwriter, they can-
not be written to the amplifier by the installer. Event 1 is the most
recent event, then Event 2, and so on. If event memory is full (Event 7
has a stored diagnostic message), then if another event occurs the 7th
event will be pushed out of memory.
NOTE: While the Bitwriter
®
can be used to read the amplifier during
