Introduction
This manual will specifically cover setup with the Crown CDi am-
plifier that our Origin Landscape speakers are designed to work
with.
For more detailed information about the Crown CDi amplifier,
refer to the Crown Operation Manual.
For useful information about the relative merits of dierent wiring
plans you may want to refer to the speaker installation manual
(available on-line).
Crown Amplifier Ins & Outs
Input Connections
Unbalanced (Most Common)
Connect your audio source to the Crown using the supplied cables
with RCA connectors on the source end Phoenix style connectors
on the Crown amplifier end. The Crown amplifier input channels
labeled CH1 and CH2. Both are identical.

Balanced
When using the Origin Landscape series in a commercial instal-
lation it might be necessary to connect the amplifier using bal-
anced wiring. Connect the wires from your source equipment to
the Phoenix connector. Be sure to observe proper polarity when
connecting the wires to the Phoenix connector. If your source
equipment uses XLR connectors please confirm the polarity or
pin out of your source equipment before terminating the Phoenix
connector. See figure 1

Output Connections
Terminating the Wires
Attach the supplied spade connectors to the ends of your speaker
cables. Then attach them to the output screws on the amplifier
and replace the supplied plastic cover to prevent a short circuit
or shock hazard.

The amplifier should not be connected to AC power until all connections
are completed. High power 70v amplifiers present a serious shock hazard.
Do not connect speaker wires to the amplifier until all other connections
are completed.

WHICH PRESET TO USE?
The Crown CDi series amplifier you purchased from Origin Acous-
tics is preloaded with 20 presets to allow allow you to optimally
configure your sound system for practically any circumstance.
The presets have been divided into two families -- the Active
Crossover family and the Passive Crossover family.
The Active Crossover family is recommended for most installs. It
will have the subwoofers on one wire run (must be channel 1) and
the satellite speakers on the other (must be channel 2). The active
crossover removes the bass from the satellites, more eectively
controls how the subwoofer interfaces with the satellites and al-
lows the custom DSP (digital signal processing) to be fed only to
the speakers they were designed for.
• Preset 2 is designed to make the LS 64 sound full range when
no subwoofer is to be used.
• Presets 7-11 require 2 or more amplifiers. They are intended
for larger installs and also give you greater control over the
balance between the subwoofer and the satellites. Presets
12-14 are for 8Ω installs and must use the 8” subwoofer and
satellites switched to 8Ω mode.

The Passive Crossover family, which is the approach you may be
most familiar with, allows satellites and subwoofers to be on a
single wire run.
• Presets 19 & 20 use the amplifier in bridged mode if only one
channel is available. This is anticipated to be used when wire
is pre-existing from a previous install.

HOW MANY SPEAKERS CAN BE
RUN ON EACH CHANNEL?
Origin Landscape speakers use an adjustable 70 volt transformer
that not only let you to set speaker’s volume level relative to the
other speakers in the system, but also allows you to increase the
number of speakers that can be run on each channel. The chart
below shows the maximum number of speakers you can use be-
fore the load becomes unsafe for the Crown CDi amplifiers (2Ω
load). If you’re using the amplifier in bridged mode you’ll need to
divide the maximum speaker number in half.
