Fig. 2.1.: Control elements and connections
You can connect a footswitch (e.g. MIDI FOOT
CONTROLLER FCB1010) to this 1/4" TS connector to
remotely enable/disable the tweeter. When the tweeter is
enabled, you get a harder, more direct sound (Hard Attack).
When the tweeter is disabled, the entire sound spectrum is
reproduced only on the bass speakers (Soft Attack).
The loudspeakers of the ULTRABASS series feature a
1/4" TS connector in the INPUT/LINK section as well as two
professional speaker connectors (compatible with
NEUTRIK® SPEAKON®). All connectors are wired in parallel,
which means that all three connections are identical in their
function. Therefore, you can connect a second speaker to
the link connector output without going directly to the
amplifier. This way, you can utilize short cables and will
require no additional connectors on your amp.
+Connecting several ULTRABASS cabinets via the link
connector reduces the input impedance: if you connect
two identical speakers, the impedance is reduced to
one half of the original value, with three speakers to a
third, and so on. Therefore, always keep in mind the
impedance value of your amplifier to avoid causing
damage by overloading. Ideally, the impedance of your
speakers corresponds to the impedance of your
amplifier. If the speaker has a higher impedance than
the amplifier, this will have no negative consequences
on the amp, but it wont be able to pass its full power to
the speaker. See chapter 4. INSTALLATION for more
information.
+Attention! Never connect two amps to one BA810.
Otherwise, you may destroy both your amps and your
speakers.
This table shows the correct polarity of the connectors:
Plus pole (POS) = Tip (TIP) on the stereo jack or 1+ on the
professional speaker connector.
Minus pole (NEG) = Sleeve (SLV) on the stereo jack or
1- on the professional speaker connector.
+Please observe the illustrations 4.1 and 4.2.
