4 Wiring Instructions

WARNING: Failure to follow the set-up and wiring instructions explicitly may cause damage to your loudspeakers and void your warranty.

Introduction

The Sentinel crossover is designed specifically for use with the drivers in the upper speaker cabinet. The crossover is housed in a separate enclosure, designed to be placed directly behind the speaker. Input to the upper speaker cabinet drivers is facilitated by a two-position terminal block, using your own speaker cable, and is for SINGLE-WIRING ONLY.

By contrast, the lower speaker cabinet is actively powered by, and directly connected to the subwoofer amplifier. Wiring between the subwoofer amplifier and subwoofer drivers is hard-wired to the subwoofer drivers.

The external crossovers must be used at all times for the upper speaker cabinet drivers. The subwoofer amplifier powers the subwoofer drivers ONLY. Do NOT connect the subwoofer amplifier (or your own amplifier) directly to the upper speaker cabinet drivers.

Because of the weight and size of the Sentinel Active Reference System, it is important to complete the set-up procedure before making wiring connections (see Chapter 3, System Set-up, beginning on page 15).

Connections from the upper speaker cabinet to the crossover cabinet is made by two wiring harnesses: a four-conductor wiring harness with labels "HIGH" and "MID" for the tweeter and midrange, and a two-conductor wiring harness with labels "LOW" for the woofer. These harnesses are hard-wired directly to the upper loudspeaker cabinet drivers (routed through the wiring tubes in the lower speaker cabinet), in order to provide the most unobstructed signal path.

Connections from the subwoofer cabinet to the subwoofer amplifier are made by a two-conductor wiring harness with labels "SUB". This harness is hard-wired directly to the subwoofer cabinet drivers in order to provide the most unobstructed signal path.

The Sentinel Active Reference System is equipped with nickel-plated brass barrier terminals for connecting the harnesses and speaker cables. Ring terminals or spade lugs designed for #10 screws are recommended for cable termination.

Do NOT over-tighten the screws.
