Connecting a Preamplifier
Example of connections to Marantz AV 10 Preamplifier:
Connecting the UNBALANCED RCA PRE OUT connector:
If using UNBALANCED RCA connectors, set the RCA/XLR INPUT selector to “RCA” and the NORMAL/BI-AMP/BTL selector to “NORMAL”. A diagram illustrates the connection from the Marantz AV10's RCA PRE OUT terminals to the AMP10's input channels.
Connecting the BALANCED XLR PRE OUT connector:
If using BALANCED XLR connectors, set the RCA/XLR INPUT selector to “XLR” and the NORMAL/BI-AMP/BTL selector to “NORMAL”. A diagram illustrates the connection from the Marantz AV10's XLR PRE OUT terminals to the AMP10's input channels.
NOTE: Be sure to configure the RCA/XLR INPUT selector and NORMAL/BI-AMP/BTL selector settings before turning the power on. If you try to change these settings after turning the power on, the settings will not change.
Bi-amp connection
Bi-amp connection is a method to connect separate amplifiers to the tweeter and woofer terminals of a speaker that supports bi-amplification. This connection enables back EMF (power returned without being output) from the woofer to flow into the tweeter without affecting the sound quality, producing a higher sound quality.
Example: Using channels 1 and 2 as a bi-amp:
Set the NORMAL/BI-AMP/BTL selector setting to BI-AMP. Connect one cable from channel 1 to the tweeter of the speaker and the other cable from channel 2 to the woofer of the speaker. Input is to the odd-numbered channel (channel 1).
NOTE: When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the speaker's woofer and tweeter terminals. Be sure to configure the NORMAL/BI-AMP/BTL selector setting before turning the power on. If you try to change these settings after turning the power on, the settings will not be applied.
BTL connection
A BTL connection uses two channels to power one speaker. Two power amplifiers are used to output antiphase signals from one input signal, achieving powerful audio reproduction.
Example: Using channels 1 and 2 for a BTL connection:
Set the NORMAL/BI-AMP/BTL selector setting to BTL. Connect one cable from the positive (+) side of channel 1 to the negative (-) side of the speaker and the other cable from the positive side of channel 2 to the positive side of the speaker. Input is to the odd-numbered channel (channel 1).
NOTE: Be sure to configure the NORMAL/BI-AMP/BTL selector setting before turning the power on. If you try to change these settings after turning the power on, the settings will not be applied.
