13. EXT AMP: This feature was originally
designed as a means to daisy-chain
two or more B-15 amps together for
additional power. This new-and-improved
Heritage B-15 could also be used as a
line out to feed an unbalanced Hi-Z input
such as a direct box or a mixer.
Alternately, it may be utilized as an
input. Any signal applied here will not be
affected by the volume controls [2, 6].
14. SPEAKER OUTPUTS: These 1/4" TS
output jacks supply speaker-level power
to the speaker cabinet. The rated power
output is 30 watts rms into a 4 or 8
load.
The Heritage B-15 cabinet is rated at
8 . When using a single Heritage B-15
cabinet with the Heritage B-15 head,
connect the cabinet to the matching 8
speaker output jack using a high quality
speaker cable.
When using the Heritage B-15 cabinet
with an additional 8 ext. speaker,
connect the two (8 ) cabinets to
the two provided 4 jacks using two
high quality speaker cables. (Two 8
cabinets in parallel equal a 4 load).
When using the Heritage B-15 cabinet
with one 4 cabinet, such as a Heritage
SVT-410HLF or SVT-810E, connect the
single 4 cabinet to either of the 4
speaker output jacks using a high quality
speaker cable.
Use speaker cables with 1/4" TS ends
only to make the connections. Do not
use instrument cables as they may
overheat.
