BlackGround 10x Speaker Base - Single Channel
Single channel means that you will have all 10 onboard BlackGround modules available for a single loudspeaker signal. A single loudspeaker signal is made up of both positive and negative polarities (Red and Black terminals accordingly on your amp or speaker posts).
So, if you will be using this single channel version on your stereo set of speakers, you will need two of these units. One for right channel, one for left channel. We will sell these at a 5% discount on both if you get them together.
Now let's zoom in for a closer look at these.
Viewing the 10x Speaker Base from the back, we see, from left to right:
An IEC C14 power inlet for an optional power cord. This has the sole purpose of grounding the unit. In this unit, the Live and Neutral pins float internally and do not provide power to this passive device. The device consumes no power, and power voltages do not enter the unit's schematics.
Two grounding terminals. These are for bridging the ground potential from a BlackGround Power Base device. Our Grounding Cables are recommended for this application. Either of the grounding terminals can be used. If grounded in this way, no power cord is needed.
A positive polarity terminal. This should receive the positive (red) signal from the amplifier.
A negative polarity terminal. This should receive the negative (black) signal from the amplifier.
Above you see the internal wiring schematic for the BlackGround 10x Speaker Base. As you can see, the Live and Neutral pins of the power inlet are not used in this device.
How to connect in three easy steps
(1) Connect the amp's positive polarity output to the "+" marked terminal of the 10x Speaker Base.
(2) Connect the amp's negative polarity output to the "-" marked terminal of the 10x Speaker Base.
(3) Connect a ground potential from your building ground to either one of the grounding terminals of the 10x Speaker Base, or use any power cord which has ground provision.
Repeat for your other audio channel and with a second 10x Speaker Base units when used in stereo applications.
BlackGround 8x Speaker Base - Dual Channel
So now let's take a look at the 8x Speaker Base - Dual Channel version. In this case if you have a two channel system you only need this one single unit.
Viewing the 8x Speaker Base from the back, we see, from left to right:
An IEC C14 power inlet for an optional power cord. This has the sole purpose of grounding the unit. In this unit, the Live and Neutral pins float internally and do not provide power to this passive device. The device consumes no power, and power voltages do not enter the unit's schematics.
Two grounding terminals. These are for bridging the ground potential from a BlackGround Power Base device. Our Grounding Cables are recommended for this application. Either of the grounding terminals can be used. If grounded in this way, no power cord is necessary.
A first positive polarity terminal. This should receive the positive (red) signal from one channel of the amplifier.
A first negative polarity terminal. This should receive the negative (black) signal from the same channel of the amplifier.
A second positive polarity terminal. This should receive the positive (red) signal from the other channel of the amplifier.
A second negative polarity terminal. This should receive the negative (black) signal from the same other channel of the amplifier.
Tip: It is recommended to use two Grounding cables with banana terminations instead of two full-fledged power cords to ground the 10x Speaker Base units, in order to save money, because most users will already own a BlackGround Power Base unit and will be able to ground directly from Power Base unit grounding terminals to their 10x Speaker Base units' grounding terminals. Therefore, no power cords on the 10x Speaker Bases are even needed. Also, it is a waste of funds to use two power cords if only the ground legs of each power cord will be used. The IEC C14 power inlet is provided only for such cases where no Power Base is used in a given system, and it is deemed that power cords represent the easiest way for the user to ground the 10x Speaker Base units.
Above you see the internal wiring schematic for the BlackGround 8x Speaker Base - Dual Channel version. As you can see, the Live and Neutral pins of the power inlet are not used in this device.
How to connect in five easy steps
(1) Connect the amp's positive polarity output to the "+" marked terminal of the 8x Speaker Base.
(2) Connect the amp's negative polarity output to the "-" marked terminal of the 8x Speaker Base.
(3) Connect the amp's other channel positive polarity output to the "+" marked terminal of the 8x Speaker Base.
(4) Connect the amp's same other channel negative polarity output to the "-" marked terminal of the 8x Speaker Base.
(5) Connect a ground potential from your building ground to either one of the grounding terminals of the 8x Speaker Base, or use any power cord which has ground provision.
Tip: It is recommended to use a Grounding cable with banana termination instead of a full-fledged power cord to ground the 8x Speaker Base, in order to save money, because most users will already own a BlackGround Power Base unit and will be able to ground directly from a Power Base unit grounding terminal to a Speaker Base unit grounding terminal. Therefore, no power cord on the 8x Speaker Base is even needed. Also, it is a waste of funds to use a power cord if only the ground leg of it will be used.
