Installation
The Hi-Fi2 Main Assembly houses the Hi-Fi2 processor, power supply, and amplifiers. It is also the
termination point for all components and connections to Hi-Fi2. The Hi-Fi2 Main Assemble can be
installed in a Vented Enclosure (HAI Part Number: 95A09-1) that can be tucked away in a closet or
basement or can be installed in a Leviton, OnQ, Channel Vision, Siemon, or other "open house" type
structured wiring enclosure using an HAI Universal Mounting Plate (HAI Part Number: 20A07-2).
The Hi-Fi2 Main Assembly should be mounted in a location that is protected from high humidity levels
and temperature extremes. An AC power outlet should be located within 5 feet.
Installing Remote Input Modules (RIM)
Audio sources can be connected directly to Remote Input Modules (RIM) in rooms that will have music
sources. Remote Input Modules connect directly to the Hi-Fi2 Main Assembly using Cat 5, unshielded,
twisted pair (UTP) for communications. Each end of the wire is terminated with an RJ45 connector.
The correct wiring scheme for the Cat 5 cable is standard EIA/TIA 568A. Properly terminating the
Cat 5 cable is crucial for the operation of the system.
It is best that no single run of Cat 5 exceeds 500 feet.
Insert the RJ45 connector on one end of the cable to the respective source input jack (1-8) under
“Remote Audio In / IR Out” on the Hi-Fi2 Main Assembly. Insert the RJ45 connector on the other end
of the cable to the jack labeled “Remote Audio” on the RIM.
Changing the Color of the RIM
The color of the RIM may be changed to complement the interior décor. The RIM is supplied with a
white faceplate and insert. Additional colors are available; contact your HAI distributor for more
information. Change the color of the RIM as follows:
1. Remove the faceplate.
2. The insert attaches to the RIM with
two latches on the right and two on the
left. Using a small-blade screwdriver,
gently depress each latch on one side
while lifting up on the insert. Once the
latches are released on one side,
remove the insert from the other side.
3. Align the latches of the new insert to
the openings on the RIM and gently
snap into place.
4. Attach the new faceplate.

Page 6
Setting the Frequency of the IR Output
When using the RIM to send IR data to source equipment, there are two
different IR carrier frequencies in which the RIM can transmit the IR
signal. The default setting of 38 kHz is used for most audio sources.
However, most cable and satellite converter boxes operate at a higher IR
carrier frequency closer to 56 kHz. Each RIM has a switch that allows
you to change the frequency of the IR output when using such devices.
To change the frequency setting, remove the faceplate and insert from
the RIM as described under “Changing the Color of the RIM”.
Once the insert has been removed, move the frequency switch (SW1)
from the “38kHz” position to the “56kHz” position.
IR Output
Each RIM ships with an IR flasher (62A08-1). The IR
flasher is used for sending IR data to the source
equipment.
When you point your source equipment remote control
at the IR receiver in the VSC and send a signal, the IR
data is routed to the appropriate RIM (to which the
source equipment is connected), which then sends the
IR signal through the IR flasher to the source
equipment.
Installing Local Sources
The Hi-Fi2 is equipped with 8 local source inputs. This is useful if your audio sources are in the same
location as the Hi-Fi2 system. Instead of connecting a RIM for each source, the audio source can be
connected directly to the local source input using 3.5mm male stereo patch cable.
Each local source input is in parallel with the corresponding input for a RIM. Therefore, only a single
audio source should be connected to the same source input, whether it is a local source input or a RIM.

Installing Volume-Source Control (VSC) Keypads
The audio sources can be selected and controlled by any Volume-Source Control (VSC). Additionally,
each VSC includes an IR receiver that allows you to remotely control the Hi-Fi2 system and/or audio
sources from any audio zone in the house. Volume-Source Control (VSC) Keypads connect directly to
the Hi-Fi2 Main Assembly using Cat 5, unshielded, twisted pair (UTP) for communications. Each end
of the wire is terminated with an RJ45 connector. The correct wiring scheme for the Cat 5 cable is
standard EIA/TIA 568A. Properly terminating the Cat 5 cable is crucial for the operation of the system.
The total distance of Cat 5 between the Hi-Fi2 Main Assembly and the VSC units must not exceed
2000 feet. It is best that no single run of Cat 5 exceeds 250 feet.
Insert the RJ45 connector on one end of the cable to audio zone input jack (1-8) under “Volume Source
Control / IR In” on the Hi-Fi2 Main Assembly. Insert the RJ45 connector on the other end of the cable
to the jack labeled “Zone Control” on the VSC.
Turning a VSC on for the First Time
When you turn a VSC on for the first time, you will need to configure which audio zone the VSC will
control. The following screen is displayed:

To configure the audio zone that the VSC will control, press the src button on the VSC.


To select the audio zone that the VSC will control, press the +button to increase the
zone number and press the –button to decrease the zone number.
Audio zone settings range from 1 to 16.

If space is available, more than one VSC can be configured to a given audio zone. This is useful if
multiple VSC keypads are installed in a large room to control a single audio zone. When multiple VSC
keypads are configured to an audio zone, all VSC keypads will mimic one another.
A maximum number of 16 VSC keypads can be installed on a Hi-Fi2 system.
Changing the Color of the VSC
The color of the VSC may be changed to complement the interior décor. The VSC is supplied with a
white faceplate, rubber keypad, and insert. Additional colors are available; contact your HAI distributor
for more information. Change the color of the RIM as follows:
1. Remove the faceplate.
2. The insert attaches to the VSC with two latches on the right and two on the left. Using a small-blade
screwdriver, gently depress each latch on one side while lifting up on the insert. Once the latches are
released on one side, remove the insert from the other side.

3. Remove the rubber keypad.
4. Insert the new rubber keypad. Align the latches of the new insert to the openings on the VSC and
gently snap into place.
5. Attach the new faceplate.
Serial Control
Hi-Fi2 can be remotely controlled
through an HAI controller or by a
device with a serial interface. When
connected, the remote device can select
an audio zone and change its power
state, source, volume setting, and mute
setting, completely configure the Hi-Fi2
system, and issue transport controls to
compatible sources.
Connect Hi-Fi2 to an HAI Omni or
Lumina series Home Control System by
inserting the supplied straight-through,
4-position modular cable between an
available serial interface connector on
the HAI controller and the modular
connector labeled “Serial Control” on
the Hi-Fi2 Main Assembly.

Ethernet Control
Hi-Fi2 is equipped with an Ethernet port which makes it
network accessible. When connected to the local
network, the Hi-Fi2 can be completely controlled and
configured by other compatible IP devices on the
network. Furthermore, when used in conjunction with
an HAI Music Gateway (HAI Part Number: 84A00-1)
or other compatible audio source, the Hi-Fi2 VSC can
display metadata (album, artist, and track) from the
source and is able to control the source using transport
control commands.
To access the Hi-Fi2 from the network, connect the port
labeled “Ethernet” to a network switch or router using
Cat 5, unshielded, twisted pair (UTP). Each end of the
wire is terminated with an RJ45 connector. The wiring
scheme for the Cat 5 cable is standard EIA/TIA 568A.
Page / Mute Input
The Hi-Fi2 paging feature offers the capability of playing a single
audio source over all zone speakers. If paging is used, the paging
audio source will be connected as audio Source 8. Hi-Fi2 is also
equipped with a Page Input which will, when activated, turn all zones
on at the preset paging volume and switch all zones to Source 8.
When the input is deactivated, all audio zones will be returned to
their previous source selection, power state, and volume setting.
When used with an HAI controller and Two-Way Voice Module with
Line-Level output and Mute/Page Control, custom announcements
can be made over all zone speakers when certain events take place.
If desired, the Page function can be used to mute all zones instead of
making an announcement. For example, you may simply want all of
the zones on the Hi-Fi2 systems to be muted when someone is at the
door or when the telephone is ringing. To configure Hi-Fi2 to mute
all zones, set the Paging Volume for each zone to “0” as described
under “Setting Paging Volume” in the Hi-Fi2 User’s Guide.
To activate the Page / Mute function, short the two wires on a mono
patch cord. When activated, all zones are turned on at the preset
paging volume (or muted) and switched to Source 8. The wires on
the patch cord may be shorted through relay contacts or a switch. If a
solid state switch is used, Tip is positive relative to Ring.

Speaker Wiring
When running the cables for speakers, use 16-gauge two-conductor or four-conductor (four-conductor
stranded is recommended for neater installation) speaker wire. Speaker cable is homerun from the
speaker location to the location of the Hi-Fi2 Main Assembly.
The Hi-Fi2 System is designed to work with one pair of 8-ohm speakers per audio zone. If additional
speakers are required in an audio zone, HAI recommends: a) use the Zone Grouping feature of Hi-Fi2
where two or more audio zones control the same source, volume, and/or power state so that any or all of
these items are controlled together; or b) use the variable output(s) and an external power amplifier.
Terminating Speaker Wires
Always observe proper orientation of the positive and negative signal for each speaker connection.
Typically, when using two-conductor speaker wire, the red wire indicates positive (+) and black wire
indicates negative (-). Another indication of positive is a dark line running through the insulation.
Four-conductor wire can also be used and makes for a neater installation. Four-conductor wire has four
separate wires in one outer jacket, making it possible to run a single speaker wire for a pair of zone
speakers. This type of wire typically uses red and black for one speaker and white as positive and green
as negative for the second speaker.
SPEAKERS SPEAKERS
Use 16 gauge speaker wire (4 conductor
stranded is suggested for neat installation)

Page 11
Variable Outputs
Zone 1 and Zone 8 are equipped with a pre-amp variable output for use with an optional power amplifier
that allows you to deliver more power to the zone speakers. This is ideal for outdoor areas or a large
living room where more power and/or additional speakers are desirable.
To connect Zone 1 and/or Zone 8 to an optional power amplifier using a stereo patch cable:
1) Connect the power amplifier to the Hi-Fi2 Main Assembly by inserting a 3.5mm stereo
connector into the 3.5mm jack labeled “Line Out Zone 1” or “Line Out Zone 8”
(HAI 62A14-1, 3.5mm male to 2 RCA male retractable patch cable may be used).
If your power amplifier is equipped with a voltage trigger that will turn on the amplifier when energized:
a) Connect the voltage trigger of the power amplifier to the Hi-Fi2 Main Assembly by inserting
a 3.5mm mono connector into the jack labeled “System Sys. On”.
b) When any audio zone is turned on, Hi-Fi2 supplies 5 VDC to the “System Sys. On” output.
c) When all audio zones are turned off, Hi-Fi2 supplies 0 VDC to the “System Sys. On” output.

The built-in power supply powers the entire system including the Hi-Fi2
processor, zone amplifiers, Remote Input Modules, and Volume-Source
Control keypads.
1) Insert the supplied IEC Power Cord into the power jack (above the
Expander connector) under the section labeled “Power” on the Hi-Fi2
Main Assembly.
2) Plug the power cord into a 120 VAC outlet. The “Standby” LED
indicator will flash for several seconds as the Hi-Fi2 system starts.
Once operational, the “Standby” LED indicator will remain
illuminated. Follow the instructions in the User’s Guide for operation.
Expanding the Hi-Fi2 System
The Hi-Fi2 System can be expanded to 16 audio zones by adding
a Hi-Fi2 8-Zone Expander (HAI Part Number: 95A12).
The Hi-Fi2 Expansion Assembly must be mounted below the
Hi-Fi2 Main Assembly, within 6 inches.
To connect the Expander, insert the supplied ribbon cable into
the Expander connector under the section labeled “To Expander”
on the Hi-Fi2 Main Assembly.
Connect the other end of the ribbon cable to the connector on the
Hi-Fi2 Expander under the section labeled “To Main”.
Refer to the instructions in the Hi-Fi2 Expander Installation
Manual.
