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 2.3 or above to access the amplifier fea- tures menu.

NOTE: A setting marked “Reserved” is for future development.

Turn On Delay - 1.5, 2, 2.5, 3, 3.5, 4 seconds (approximate time delays). Delays the amplifi- er 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 amplifi- er.

Service Code Display - OFF, Flash Code on LED, Reserved, Clear Last Fault.

When set to “Off” the service code display will not be displayed on top of the amplifier (see Top Light Options feature below) and the amplifier operates nor- mally.

When set to “Flash Code on LED”, the LED on top of the amplifier will be enabled to flash the diagnostic code (see table below).

The “Clear Last Fault” setting is used by your installer to clear the last fault event detected by the amplifier.

NOTE: When the Clear Last Fault setting is used, execute a “read” cycle from the Bitwriter® prior to attempting further writes. This resynchronizes the Bitwriter®.

Input Gain Range (Volts) - Default, 0.15–0.50 V, 0.50–1.00 V, 1.00–3.00 V, 3.00–5.00 V. This feature allows the input gain range to be limited. This feature is useful to prevent the amplifier from being overdriven. The “Default” setting turns the Input Gain Range feature off, the input gain adjustment is settable over the full range of the control.

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.
