RESISTOR/CAPACITOR SUBSTITUTION TABLES fOR PROGRAMMING CUSTOM CROSSOVER fREQUENCIES IN LINKWITZ-RILEY (10B-LR) MODELS
The resistors used to program specific crossover frequencies in the Linkwitz-riley filters are often installed directly on the 10B-LR main
boards, but they can also be installed on small programming boards as shown in the illustration “10B-LR PROGRAMMABLE LINK
-
WITZ-RILEY STEREO CROSSOVER”. Since the resistor values are dependent on the capacitor values used on the 10B-LR main
board it is essential that the exact capacitor values are determined before attempting to find the correct resistor values for any particular
crossover frequency. You may notice that the low pass capacitors (C1a, C1b, C2a & C2b ~ six axial capacitors in a row in the front left
quadrant of the board) may be either 20nF, 22nF or 24nF. Also, please note that C1 is actually formed by paralleling two capacitors of
the same value. Parallel capacitors are also used, on occasion, to produce other values of capacitance where needed. The value of
two capacitors in parallel is equal to the sum of the two capacitances.
Please note that Bryston recommends that any component substitutions be performed only by qualified service personel and that
Bryston cannot be held responsible for any damage caused by unqualified personel. Please contact your Bryston dealer or Bryston
Limited directly if you have any questions about performing any modifications to Bryston equipment.
Capacitors: Low pass: C1=40n, C2=20n, High Pass: C(ab)=4n7
