GENERAL OPERATION
THE BBE 862 IS A LINE LEVEL SIGNAL PROCESSOR AND IS TO BE CONNECTED PRIOR TO THE POWER AMP
IN ANY AUDIO SYSTEM. SIGNIFICANT DAMAGE MAY BE INFLICTED TO THE BBE 862 OR ANY SUBSEQUENT
COMPONENT IN THE SYSTEM IN THE EVENT THE OUTPUT OF A POWER AMP IS CONNECTED DIRECTLY TO
THE BBE 862.
In order to reduce the risk of damage to any equipment, properly connect all cables and power cables before turning on
any components in the system. Most important of all, ALWAYS TURN ON THE POWER AMPLIFIER LAST TO AVOID
DAMAGING THE SPEAKERS OR THE AMP.
The BBE 862 may be utilized in a number of different environments. Having balanced connections, the BBE 862 is
able to drive long signal lines with virtually no added noise or distortion. Nor will it have any adverse affect on the
sound quality of the music program.
Both channels of the BBE 862 are completely independent from each other. One channel of the BBE 862 may be
used at a time or each channel may process different signal sources simultaneously.
The effects loop is the ideal placement in the signal chain of a guitar application. In a pre-amp, keyboard or P.A.
application, the BBE 862 works best as the last component in the signal chain, just before the crossover or power amp.
Important: In pro audio applications, never connect the BBE 862 into the effects loop. The inherent phase
shift of the BBE Process will cause phase cancellation resulting in a partial loss of signal.
BBE AND EQUALIZATION
The most common question asked of the BBE Sound, Inc. service department is: "Where does the BBE Processor
connect in the signal chain, before or after the equalizer?" Many people find that the same amount of equalization is
no longer needed, if at all, when a BBE processor is used. Additionally, the amount of equalization used will help
determine the BBE 862’s proper location in the signal chain: if the EQ is being set to give the room a flat response as
determined by a spectrum analyzer, the BBE 862 will work properly before or after the EQ. (Placing the BBE 862 after
the EQ is recommended.) If the EQ is being used for drastic tone alteration, the recommended placement would be
before the EQ. Neither of these configurations will harm the BBE 862.
When the BBE 862 is being used in a single instrument application, guitar, keyboards, etc., it may be advantages to
experiment with the proper placement of the BBE in the signal chain. The BBE 862 will improve the sonic quality of the
instrument and any effects that may be present as well. Important: Generally, reverb and delay do not affect the
BBE negatively. However, it is possible that with a large amount of effects added to an instrument that the BBE
may process irregularly. If this occurs, reconnect the BBE 862 as the first item in the processor chain.
Use the following illustrations as a starting point for proper placement of the BBE 862.
