1 Welcome

The Xs Series of power amplifiers from Crown®
represents a new era in affordable, quality
power amplification. The line consists of five
models: four 2-channel units and one 4-chan­nel unit, each in a uniform, rugged chassis. The
Xs Series incorporates the best of tried-and­true design principles and innovative features.

Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.

In addition, Xs Series amplifiers include a
number of features which require some expla­nation before they can be used to their maxi­mum advantage.

Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.

1.2 How to Use This Manual

This manual provides you with the necessary
information to safely and correctly setup and
operate your amplifier. It does not cover every
aspect of installation, setup or operation that
might occur under every condition. For addi­tional information, please consult Crown’s

Amplifier Application Guide (available online at

www.crownaudio.com), Crown Technical Sup­port, your system installer or retailer.

We strongly recommend you read all instruc­tions, warnings and cautions contained in this
manual. Also, for your protection, please send
in your warranty registration card today. And
save your bill of sale — it’s your official proof
of purchase.

2 Setup

2.4 Choose Input Wire
and Connectors

Crown recommends using pre-built or professionally wired bal­anced line (two-conductor plus shield), 22-24 gauge cables and
connectors. At the amplifier inputs, use either:

• 3-pin male XLR cable ends,

• TRS or TS 1/4" phone plugs, or

• Phoenix-style connectors (2-channel models only).

Unbalanced lines may be used, but may result in noise over long
cable runs.

Figure 2.3 shows XLR wiring, Figure 2.4 shows 1/4" phone plug
wiring, and Figure 2.5 shows Phoenix-style connector wiring.

NOTE: Custom wiring should only be performed by qual­ified personnel.

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high­quality, two- or four-conductor, heavy gauge speaker wire and
connectors. You can use banana plugs, spade lugs, or bare wire
for your output connectors (Figure 2.6). Also, in the 2-channel
models, you can use a 4-pole Speakon
and Table 1). To prevent the possibility of short-circuits, wrap or
otherwise insulate exposed loudspeaker cable connectors.

Note: Binding post outputs on European models come
with safety plugs installed to prevent European power­cord plugs from being inserted. The top & bottom entry
positions for these connectors should therefore be used
with European models.

Using the guidelines below, select the appropriate size of wire
based on the distance from amplifier to speaker.

Distance Wire Size

up to 25 ft. 16 AWG
26-40 ft. 14 AWG
41-60 ft. 12 AWG
61-100 ft. 10 AWG
101-150 ft. 8 AWG
151-250 ft. 6 AWG

CAUTION: Never use shielded cable for output wiring.
