PB9 Sound Kit Installed

BigSoundTM PB9 Features:
16-bit Sound Reproduction
A 16-bit combintation microprocesssor and digital signal processor is used to produce museum-quality sound that cannot be matched by an 8-bit solution
3 Watts Power
Strong 3 Watt amplifier produces more than sufficient volume for out-of-doors use.
3-Volt Low-speed Operation
Most sound units do a poor job at low power settings - meaning at low run speeds. Not so with the PB9, it is fully operational at power settings as low as 3 Volts. There is usually some voltage loss from the track through the wheels and contacts to the board, so the track voltage may have to be 5 or 6 volts for continuous operation in order to keep the battery fully charged.
4 triggers for external control
4 different inputs provide flexibility for attaching external controls.
Twice the memory of the 2K2
The increased memory size of the PB9 means we will be adding more sounds, effects and features. Just as you asked for. Look for new and improved sounds as well.
Advanced Circuit Protection
Not likely that you'll blow up a board from making a minor installation error.
BigBoostTM is on the board
No need to purchase a separate, slow-speed booster, it is on the board at no extra price.
Board Size
The board is 2.54 " x 0.874" x 0.50" -- smaller than the BigSoundTM 2K2 board.
Smaller Battery
The PB9 uses a 3.6V 480mAh 2/3AAA NiMH battery pack - 53% the size of the 3.6V 300mAh 2/3AA Ni-Cad 2K2 battery.
Built-in Battery Charger
No need to purchase an external battery charger. The battery is charged automatically by the PB9.
Coal loading
The sound of coal being loaded into the tender from a chute on a coal loading tower.
Coal shoveling
The sound of coal being shoveled into the fire box by the fireman.
DCC Sound Decoder Built-In
It isn't necessary to purchase a separate DCC function decoder to control sounds like the whistle and bell on a PB9 - a DCC sound decoder is built-in. NMRA Compliant.
Extensive Sound Library
Over 70 sounds and growing.
Labored Chuff
Ultra realistic labored chuff when a locomotive starts to climb a hill. Usually triggered from a track magnet.
Lineout for external amplification
Real-world applications can be achieved including high-volume amplification by using the low-noise lineout capability.
Opto Isolation Not Necessary
Opto-isolation is not necessary when using the PB9 with remote control.
Polyphonic Integration
Different sound-features are generated so that one does not distort the other For example, bell stands out clearly from the chuff.
Manual and Automatic Opeation
Manual and automatic operation can be achieved from the same board.
Simple remote programming
No buttons to push or wires to configure. The PB9 is 100% configurable from any personal computer by using our simple computer interface.
Tunnel Fade
Configure for an ultra realistic fading of the chuff as the locomotive enters a tunne. Can be triggered from an appropriately placed track magner.
Voltage controlled whistle & bell
Bigsound PB9 can be configured to allow the voltage to control the whistle and bell.
Water Filling
The sound of water rushing into the tender.
