X-OVER
This switch lets you control the X-over frequency between subwoofer
and Mid-High-range satellite cabinets. The factory setting (100Hz)
is ideally suited for 12” satellite speaker systems. The 160Hz setting
matches top cabinets and protects the 10” or 8” transducers’ diaphragms
from mechanical overload. When employing top cabinets with 15”
speakers, the 80Hz position mostly provides improved sound.
SUB LEVEL
This control sets the volume of the PowerSub 315 in a setting range
between -∞dB to +10dB, while 0dB marks the center position.
Always adjust the PowerSub 315’s output level as precise as possible
and use the mixer’s bass controls for minor sound corrections only.
CONTROLS AND INDICATORS
LEFT SATELLITE SPEAKER OUTPUT, RIGHT
SATELLITE SPEAKER OUTPUT
Outputs for the connection of satellite cabinets (e.g.
DYNACORD D 12). Each output provides a power
capacity of up to 500W into 4 ohms, offering the
possibility of connecting up to two 8 ohms satellite
speaker systems (e.g. DYNACORD D 12) per
output.
EXTERNAL SUB OUTPUT
This output socket is for the connection of up to
two additional passive subwoofers (e.g. one or two
DYNACORD SUB 115). Maximum output power of
the output is 500W into 4 ohms, when the MODE
SWITCH is set to ‘INTERNAL+EXTERN‘.
MODE SWITCH
When set to ‘INTERNAL SUB ONLY‘, only the
internal subwoofer is used and driven with 1000W /
8 ohms while the ‘EXTERNAL SUB OUTPUT‘ socket
is switched off.
When set to ‘INTERNAL+EXTERNAL‘, the
integrated power amps output power is distributed
between the internal and externally connected,
passive subwoofers. Compared to the ‘INTERNAL
SUB ONLY‘ setting and despite the fact of power-
output distribution, this setting provides a little bit
higher overall SPL because of the increase in the
total diaphragm surface and the lower mechanical
excursion of each diaphragm.
