Bi-Amplification Connections

Bi-Amplification allows the best performance from the TAD Reference One loudspeaker by using dedicated amplifiers for low- and high-frequency sections. There are two possible configurations, commonly referred to as horizontal and vertical bi-amping.

WARNING:

Remove the shorting links before connecting speaker cables in bi-wiring connections. Failure to do so may result in damage to your amplifiers.

Vertical Bi-Amping

With this configuration, identical stereo amplifiers are used for each loudspeaker. One channel of each amplifier drives the low frequency section and the other channel drives the high frequency section, as shown in Figure 10. Connect one set of wires and amplifier channel to the bottom set of binding posts (bass driver-specific network). Then connect a second set of wires and the other amplifier channel to the top binding posts (CST-specific network). Take care to connect both (+) wires to the (+) amplifier terminals and both (–) wires to the (–) amplifier terminals.
