Although it is possible to power the Sentinel Active Reference System with a single stereo amplifier, it is recommended to separate the amplification into left and right channels. This is accomplished by using two mono amplifiers.

Separating the left and right channel amplification eliminates amplifier inter-channel modulation due to the amplifier's finite output impedance and aids in preserving the Sentinel's pristine phase relationships. Cross coupling effects between the channels are minimized, thereby maintaining proper stage width presentation. Isolating the power supply signals also allows better noise rejection, resulting in improved focus, dynamics, and low-level detail.

When using two mono amplifiers, the Sentinel Active Reference System external crossovers MUST be used.

For powering the upper speaker cabinet drivers, your amplifiers are driven with a full-range signal from the pre-amplifier, and the frequency division is performed by the passive crossover.

Use of active (electronic) crossovers for the Upper Speaker cabinet drivers will result in inferior sound quality and may damage the drive units.

When using two mono amplifiers, it is important that they are identical units. It is also important to be aware of the absolute polarity of the amplifiers. If the amplifiers invert phase, be sure to compensate by reversing the polarity of the speaker leads at the amplifier's output terminals.
