Sonance BBE - Manual (Page 2)

CONTROLS AND INDICATORS
(see illustration to the right)
1. Status LEDs: Illuminate to show if the BBE process is ON, and how
much processing (+6dB or +9dB) is being applied.
2. BBE ON/OFF switch: In the OFF EXT . position, BBE processing is
bypassed; in the ON position BBE processing is applied.
• When this switch is in the OFF EXT . position BBE processing can be
automatically activated when an external control voltage is applied to
the BBE ON/OFF EXT. CTRL. connector.
3. BBE ON/OFF EXT. CTRL. connector: When a control voltage appears at this
connection and the BBE ON/OFF switch is in the OFF EXT . position,
BBE processing is automatically activated.
• The connection accepts AC or DC control voltages between 5V and 24V.
4. BOOST LEVEL +6dB EXT ./+9dB switch: Sets the amount of BBE processing
being applied to either +6dB or +9dB.
• When this switch is in the +6dB EXT . position the amount of BBE processing being applied can be automatically changed to +9dB when an external control
voltage is applied to the BOOST LEVEL EXT. CTRL. connector.
5. BOOST LEVEL EXT. CTRL. connector: When a control voltage appears at this connection, and the BOOST LEVEL switch is in the +6dB EXT . position, the amount
of BBE processing being applied is automatically changed to +9dB.
• The connection accepts AC or DC control voltages between 5V and 24V.
CONNECTIONS
(see illustrations on page 3)
Systems With No External Control Capability
1. Connect the BBE module’s Input jacks to the stereo line-level source.
• If you’re operating the Sonamp in the bridged mode, use the R input only.
2. Connect the Sonamp’s speaker outputs to the speakers.
3. If you wish to feed the source’s signal to additional amplifiers, connect them to the BBE module’s Output jacks.
Note: The signal sent through the module’s Output jacks is not BBE processed.
Systems With External Control Capability
The BBE sound enhancement process can be activated and the amount of BBE processing changed by an external control voltage. This allows an audio system
with two different sources to employ BBE processing for only one source, or to employ different amounts of BBE processing for the different sources.
The example on page 3 shows a system with two sources: a CD player playing uncompressed audio that doesn’t require BBE processing, and an iPod® playing
compressed audio files that could benefit from BBE enhancement. Both sources are connected to a Sonance AL1 Line-Level Switcher that automatically
switches to the iPod connections whenever it senses an audio signal from the iPod. Whenever AL1 selects the iPod input it also sends a +12V control voltage to
the BBE module’s BBE ON/OFF EXT. CTRL. connector, which activates the BBE processing.
When the AL1 no longer detects an audio signal from the iPod it automatically switches to the CD player input and removes the +12V control voltage.
When the control voltage is removed the BBE module switches the BBE processing off.
The BBE module has a second control voltage input (the BOOST LEVEL EXT. CTRL. connector) that operates in the same way, but changes the amount of BBE
processing from +6dB to +9dB. This connector can be employed when different amounts of BBE processing are desired for two different sources.
Note: The BBE module’s External Control inputs can also be triggered by voltage from a Crestron or similar control system.
1. Connect the BBE module’s Input jacks to the AL1 switcher’s Outputs.
• If you’re operating the Sonamp in the bridged mode, use the R input only.
2. Connect the outputs of the two sources to the AL1’s A and B inputs.
• Connect the source that you want BBE processed to the B inputs.
3. Connect the AL1’s Control Output to the BBE module’s BBE ON/OFF EXT. CTRL. input.
• Make sure that the module’s BBE ON/OFF switch is in the OFF EXT . position.
4. Connect the Sonamp’s speaker outputs to the speakers.
5. If you wish to feed the AL1’s signal to additional amplifiers, connect them to the BBE module’s Output jacks. (The signal through the jacks is not BBE
processed).
• If the additional amplifiers are equipped with BBE module, run parallel control voltage connections to the other BBE modules.
