0B CROSSOVER OWNER’S MANUAL for Models 10B-STD, 10B-SUB & 10B-LR
INTRODUCTION: The 10B crossover is available in three stock versions; 10B-SUB incorporating frequencies more suitable to sub-woofer applications (40Hz to 500hz), 10B-STD which is more applicable to speakers requiring frequency control in the mid-band and tweeter areas (70Hz to 4500Hz) and the 10B-LR, which uses plug in resistor programming cards to set the crossover frequency.
POWER AMPLIFIERS: When power amplifiers of different power capabilities are used, the woofers will likely be driven by the most powerful amplifier and the tweeters by the least powerful amplifier since the woofers can generally be expected to be less efficient.
24g stranded, tinned copper conductors and locking XLR connectors with metal shells and gold plated contacts. Unbalanced cables use single conductor shielded co-axial cable with gold plated male phono (RCA) plugs in metal shells.

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 LINKWITZ-RILEY STEREO CROSSOVER”.
