ControlSpace™ ESP-88 Engineered Sound Processor Safety Instructions & Install Guide
Important Safety Instructions Caution marks on the product normally, or has been dropped. Do not attempt to service this product yourself. Opening or removing covers may expose you to dangerous voltages or other hazards. Please call Bose to be referred to an authorized service center near you. These CAUTION marks are located on the back of the product.
Important Safety Instructions General precautions This audio signal processor requires two 1.75" (4.4 cm) rack space units with 12.8" (32.5 cm) inside depth. When mounting, use four screws with washers to prevent marring the front panel. Neoprene rubber washers are a good choice because they grip the screw heads and prevent the screws from backing out due to vibration or during transportation. CAUTION: Place the unit where it will be protected from heat and allow adequate ventilation.
Introduction Quick start Introduction ® • Install the ControlSpace Designer software included in the box (always check www.pro.bose.com for software updates.) The Bose ControlSpace ESP-88 engineered sound processor is a flexible, expandable and highquality audio signal processor for engineered sound applications such as churches, theaters, auditoriums, and sports venues. The base model (ESP-88) includes eight inputs (microphone or line-level selectable) and eight line level outputs.
Front Panel Indicators and Features Front Panel 1. Status indicator 6. Serial indicator Green = Netlist loaded, operating Red Yellow = DSP resource shortage (delay or cycles) Yellow = RS485: CC-16 controller command received Red = Error in netlist Off = No netlist loaded Green = RS485: CC-16 controller command transmitted = RS232: Rx/Tx 7. Ethernet indicator 2. Power indicator Green = Power on Green = Link Red Yellow = Tx activity = Fatal error Red = Rx activity 3.
Rear Panel Controls and Connections Rear Panel 1. Mic/line inputs 6. GPIO slot 2 Four balanced mic/line inputs (audio input connectors are green) in slots 1 and 3. These are inputs S1-1 through S1-4, and S3-1 through S3-4 in the ControlSpace™ Designer software. For optional 2nd GPIO card 7. Power switch ON/OFF AC power 2. Line outputs 8. AC cord inlet Four balanced line outputs (audio output connectors are orange) in slots 2 and 4.
Rear Panel Controls and Connections Mic/Line inputs Inputs include a 5k ohm pull-up resistor allowing SPST switches to be wired from input to ground. Potentiometers can be wired in series from the control input to ground. The ESP-88 (base model) includes two "4 x 4" Mic/Line cards. Each of these cards occupy two slots. The input connectors and the input LEDs appear in the first slot, the output LEDs and connectors (orange) appear in the second slot.
Modularity and Expansion Flexible architecture The ESP-88 employs a flexible, modular architecture. The flexible architecture provides two levels of DSP performance: up to 32 general purpose control inputs and outputs, and up to 64 digital audio channels; or up to 32 analog audio channels. Audio Cards: 4x4 mic/line card PC037533 Occupies two audio slots. Four microphone or line level inputs (software selectable), and four line level outputs. The ESP-88 includes two 4x4 Mic/line cards.
Troubleshooting No Power • Turn power on, plug in power cord. Power is on but no sound • Verify that there is an input signal from the source. The audio input indicator should be green (or yellow). • Verify that there is an output signal. The audio output signal indicator should be green (or yellow). • If there is an input signal (indicator green) and no output signal (indicators off), the ESP-88 may be muted, output levels may be down, or the unit may be completely unprogrammed.
