Set Up Section
To correctly set the ain control of the amplifier to match that of the source (headunit) use the followin setup routine:
Turn the ain control to minimum on the amplifier.
Ensure the bass boost is set to 0 dB.
On the headunit set all crossovers ( if applicable) to flat and both bass and treble to zero.
Turn up the source (headunit) to approx 3/4 volume.
Very slowly turn up the ain on the amplifier until distortion can be heard in any of the speakers or until the volume reaches
an uncomfortable listenin level when this is reached turn down the ain control sli htly.
The gain control is now set.
The settin of the crossover will depend on what kind of speaker you are installin .
For a subwoofer it is recommended that the crossover is set to Low Pass and the frequency is set to match that of the
speakers specifications, or your preferred frequency - this is usally about 60 - 120
For a pair of full ran e speakers it is recommended that the crossover is set to Flat. The two frequency controls will then
have no effect on the amplifiers output and the speaker will receive a full ran e si nal. However, usin the hi h pass
crossovers will allow more control of your speakers. By removin the bass (low frequencies) the speakers can perform at
hi her volumes with less distortion.
Note:
By usin the crossovers correctly you will not only len then the life of your speakers but you will also et better performance
from them. To optimise your setup seek the advise of a professional installation en ineer or visit your local VIBE audio dealer.
Amp strapping
The VIBE Deep SpaceBox Bass 1 amplifier is capable of being strapped together to deliver the combined output of both amplifiers into
a single channel.
NOTE: only identical amplifiers may be strapped together.
Strapping procedure
· Connect the CA input from the source unit to the left and right CA input of the master amplifier.
· Connect a mono CA lead between the SLAVE OUT output of the master amplifier and the SLAVE IN input
· Set the source switch of the master amplifier to normal
· Set the source switch of the slave amplifier to slave in
· Set the phase switch of the master amplifier to 0 degrees
· Set the phase switch of the slave amplifier to 180 degrees
· Connect speaker cable between the negative speaker output of the master amp and the negative speaker output of the slave
amplifier. The cable must be of the same gauge you will be using to connect the amplifiers to the subwoofer
· The master positive speaker output is to be connected to the subwoofer positive terminal
· The slave positive speaker output is to be connected to the subwoofer negative terminal
