BOX TO INSURE THESE ITEMS ARE INCLUDED: 1. If any of these items are found to be damaged or missing, immediately contact the BBE dealer you purchased it from. [. . . ] For simplification, we will follow though programming all the parameters for a single output. Range is ­40 dB to + 6 dB 7. 6. 1. 3 Polarity: Set the polarity for Output 1. Switching this will change the phase of the signal 180 degrees. 7. 6. 1. 4 Delay: Set the Delay time for Output 1. Delay is used to align drivers in a stack that may be in different vertical planes. Delay range is 0ms to 7ms selectable in . 5 ms increments. 7. 6. 1. 5 HPF: This is part of the crossover function. Sets the "knee" (corner frequency) and filter slope type for the HiPass Filter (HPF). Frequencies below the selected frequency will be filtered by the selected filter type and slope. Press the PARAM dial to toggle between these two parameters on the display. 7. 6. 1. 6 LPF: Set the "knee" (corner frequency) and filter slope type for the LoPass Filter (LPF). Frequencies above the selected frequency will be filtered by the selected filter type and slope. Press the PARAM dial to toggle between these two parameters on the display. 11 ® OPERATION HiPass: frequency range 10Hz~16. 0KHz LoPass: frequency range 35Hz~22. 0KHz Use HPF and LPF together to define the frequency band for this channel of the crossover. 7. 6. 1. 7 PEQ: Set the parameters for the five available bands of parametric EQ. Press the PARAM dial to toggle between the three parameters on the display. Pressing the ENTER button in this mode will select the symbol in the upper right corner. Depending on other settings, the choices will include some or all of the following: means PEQ means Lo shelf means Hi shelf means PEQ bypass Q is 0. 5 to 10 and Hi Shelf or Lo Shelf. NOTE: when using Hi shelf or Lo shelf, set Gain=0. 0dB, change Q-value to Hishelf/Loshelf. } { = (PEQ), } (Lo shelf), { (Hi shelf), = (PEQ bypass) The choices for the PEQ center frequencies are 31 ISO frequencies between 20 Hz and 20 kHz. Gain is +/- 12 dB 7. 6. 1. 8 Limiter: The limiter is used to limit the signal going to the output stage and ultimately the amps, to a predetermined maximum level, with the intention of preventing clipping and its resultant distortion. There are four parameters available to set for the Limiter The signal BEFORE gain control and AFTER limiter processing 1. Input Level sets the point at which the limiting circuitry will activate. A lower input level will activate the limiter sooner, affording more protection, but possibly creating more sonic artifacts if the limiter is activating and deactivating too frequently. Ideally, the limiter should be set so that it activates occasionally on peaks in the program. This control is also tied to the front panel level display meter for its selected output. As you lower the Limiter input level, the sensitivity of the meter will increase. This means a lower input level will result in the same signal showing more level on the Output channel display. Ideally, the output level should just approach and occasionally cross into limiting. This is the amount of time that elapses before the limiter reduces the 12 OPERATION gain to the program level after the threshold point has been exceeded by the incoming signal. Generally, set shorter attack times on outputs that are feeding mids and highs and longer attack times for lows and subs. [. . . ] This circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation even at high operating levels. The automatic servofunction recognizes the presence of unbalanced connectors and adjusts the nominal level internally to avoid level differences between the input and output signals (correction 6 dB).
