ZXSUM8 SUMMING INTERFACE
Owner’s Manual
Authorized KICKER Dealer:
Purchase Date:
The ZXSUM8 is a unique interface with the ability to sum (or mix) multiple high-level/speaker-level signals together to a single, low-level RCA output. The ZXSUM8 greatly simplifi es upgrading or adding an amplifi er (or amplifi ers) to your factory source unit. Channels 1–4 can be independently switched internally to function as stereo line output converters (LOCs) instead of the summing function.
Features
•4 stereo speaker-level inputs
•4 line-level stereo RCA outputs
•1 stereo RCA aux-input
•Balance levels from multiple speaker-level sources
•Sums up to four speaker-level stereo pairs down to a single stereo RCA low-level output
•Each stereo channel is capable of both summing and line-output conversion; switched internally
•Integrates portable media direct to your amp using aux-in and level control

CONFIGURATION
Internal Mode Switches: Change the mode of channels 2–4 between summing plus line-output conversion (LOC) and line-output-conversion-only by fl ipping the internal switches, accessible by removing the cover of the ZXSUM8.
Use LOC-ONLY mode to convert a channel’s input from high-level (speaker-level) to a low-level signal suitable for connection to an amplifi er.
Use SUM+LOC mode to mix the channel in question with Channel 1. The mixed signal appears on the Channel 1 output at low-level suitable for connection to an amplifi er. The channel’s original signal is also converted to lowlevel then passed through to its corresponding output.

OPERATION
Maximum LED: This LED will illuminate when the signal level is slightly below clipping. When the ZXSUM8 input levels are properly set, this LED will fl icker when your stereo is operating at full volume.
Channel Sum LED: This LED will illuminate when the corresponding channel is being summed to Channel 1. See the CONFIGURATION section for further details.
Level Adjustment: Turn the gain on your amplifi ers to the lowest setting and disconnect them from the ZXSUM8. Turn your source unit to approximately 3/4 volume. Adjust the level controls on the ZXSUM8 until the MAXIMUM LED is fl ickering. Turn your source unit to minimum volume. Reconnect your amplifi ers and test your system. You may wish to readjust the levels on the ZXSUM8 to taste.
Remote Turn-on: Connect the remote turn-on lead from your source unit to the REMOTE IN terminal on the power connector. If a remote turn-on lead is not available, a 6V DC offset from Channel 1 will be detected when your source unit has been turned on. The REMOTE OUT terminal will then have +12V out for turning on other devices. Use 18 gauge or larger wire.

Channel 3 Signal Sense: If no signal is present at the Channel 4 input, the signal connected to the Channel 3 input will be routed to both the Channel 3 and Channel 4 outputs.
ZXSUM8 Remote: The remote provides level control of the output of Channel 4. As shown in the installation diagrams, we
recommend always using Channel 4 as your subwoofer channel so that you can control the bass level with this remote. When the AUX-IN switch is depressed the Aux-In LED will illuminate, and the ZXSUM8 source will be switched from the high-level inputs to the low-level AUX input.

INTERFAZ SUMADORA ZXSUM8
Manual del propietario
Distribuidor autorizado de KICKER:
Fecha de compra:
El ZXSUM8 es una interfaz única con la capacidad de suma (o mezcla) de múltiples señales de alto nivel, junto a un solo de bajo nivel de salida RCA. El ZXSUM8 simplifi ca en gran medida la actualización o adición de un amplifi cador (o amplifi cadores) a su unidad de fábrica de origen. Los canales 1–4 se pueden cambiar internamente de forma independiente para funcionar como convertidores de salida estéreo de línea (LOC) en lugar de la función de síntesis.
Características
•4 entradas estéreo de nivel de bocina
•4 salidas RCA estéreo de nivel de línea
•1 entrada RCA estéreo auxiliar
•Balancea los niveles de múltiples fuentes de nivel de bocina
•Añade hasta cuatro pares estéreo de nivel de bocina a una sola salida RCA estéreo de nivel bajo
•Cada canal estéreo es capaz de añadir y de realizar la conversión de salida de línea, con conmutación interna
•Integra medios portátiles directamente al amplifi cador utilizando el control de entrada auxiliar y de nivel
