Getting started
• Do not connect the AC power cord until all other connections have been made.
• Since different components often have different terminal names, carefully read the instructions supplied with the components you are going 
to connect.
Connecting a TV
To view pictures and on-screen displays, connect the TV to the center unit.
 You can get better picture quality in the order — Component video > S-video > Composite video.
 Distortion of picture may occur when connecting to the TV via a VCR, or to a TV with a built-in VCR.
 You need to set “MONITOR TYPE” in the PICTURE menu correctly according to the aspect ratio of your TV. (Apg. 49)

To connect a TV through the component video input jacks
If your TV has component video input jacks, connect them using a component video cord (not supplied) to view a high quality picture.
 Connect “Y” to “Y”, “P
B” to “PB”, “PR” to “PR” correctly.
 If your TV supports progressive video input, you can enjoy a high quality picture by setting the progressive scan mode to active. (Apg. 22)
NOTE
 If the component video input jacks of your TV are of the BNC type, use a plug adapter (not supplied) to convert the pin plugs to BNC plugs.
 The component video signals can be output only when you select “DVD” as the source to play. (A
pg. 20)

To connect a TV through the composite or S-video jacks
Connect the TV using the composite video cord (supplied) or an S-video cord (not supplied).
If your TV has an S-video (Y/C-separation) jack, you can get better picture quality than by using composite video connection.
 Connect the S-video cord by matching the 
 mark on the plug to the one on the rear of the center unit.

Connecting the FM and AM antennas
Make sure the antenna conductors do not touch any other terminals, 
connecting cords and power cords. This could cause poor reception.

AM loop antenna
Setting up supplied AM loop antenna
Attach the AM loop to its base by snapping the tabs on the loop into 
the slot on the base.
 
Connecting AM loop antennaIf reception is poor
Connect an outdoor single vinyl-covered wire antenna (not 
supplied) to the AM EXT terminal. (Keep the AM loop antenna 
connected.)
 Twist together both wires. 

FM antenna
Connecting supplied FM antenna
If reception is poor
Connect an outdoor FM antenna with standard type (75 C coaxial) 
connector.
NOTE
 Disconnect the supplied FM antenna before attaching a 75 C
 coaxial 
connector (the kind with a round wire going to an outdoor antenna).
 We recommend that you use coaxial cable for the FM antenna as it is 
well-shielded against interference.
If the antenna cord is covered with the insulation 
coat, twist and pull the insulation coat off and 
remove.
Press and hold down the terminal 
clamp.
Insert the antenna cord.
Release finger from the clamp.

Connecting the powered subwoofer
Connect the supplied powered subwoofer (SP-PWM65/SP-PWM55/SP-PWM45) using the system cord (supplied).
• Connect the system cord by matching the 
 marks on the plugs to the ones on the center unit and powered subwoofer.
Connecting the satellite speakers


Speaker layout
When positioning the speakers, to obtain the best possible sound 
from this system you need to place all satellite speakers at the same 
distance from the listening position with the front of each speaker 
facing toward the listener.
When you cannot place them at the same distance from the 
listening position, you can make adjustment so that 
speakers operate as if they are placed at the best position. 
(A
AA Apg. 50)
 Normally place the powered subwoofer in front of you. (Since 
bass sound is non-directional, you do not need to place it at the 
same distance as the other speakers.)
NOTE
 Although the satellite speakers and the powered subwoofer are 
magnetically shielded, the TV screen may appear mottled. In this 
case, keep the distance between them to the TV to over 10 cm 
(4 inches).
 For safety reasons, always ensure that there is sufficient space behind 
the powered subwoofer.
 When you position the satellite speakers in a relatively high place, 
such as the top of your bookshelf, place them on a flat and level 
surface.
 Speaker grilles are not removable (except SP-THM55C and 
SP-THM55F). Trying to remove them by force may damage them.
TH-M55/TH-M45
 The illustrations of speakers are of TH-M55.
NOTE
For TH-M65 only: Be sure to place the powered subwoofer to the TV’s right. If you place 
the powered subwoofer to the TV’s left, keep sufficient distance 
between them to prevent the TV screen from appearing mottled.
 Do not lean against the satellite speakers, as the speakers could fall 
down or break, possibly causing injury. Especially be careful not to 
let children lean against them.

Assembling the satellite speakers (TH-M65 only)
Each speaker (except the center speaker) has been divided into two 
parts for shipment. Before connecting the satellite speakers, first 
assemble them by following the procedure below.
Before assembling —
 Prepare a Phillips screwdriver.
 Take care not to drop the stand while assembling; otherwise, it 
may cause damage to the floor or injury.
 Ensure enough space exists for assembly and installation.
 Spread a large, thick cloth on the floor where you assemble the 
speakers, so you can protect the floor and the speaker itself.
1Connect the speaker connectors to the 
stand connectors.
 Be sure to connect the speaker connectors by matching their 
sizes.
2Join the stand to the speaker section.
3Fix the stand to the speaker section.
 Be sure to tighten the screws firmly.
Repeat the procedure from step 1 to assemble the other satellite 
speakers.
NOTE
 Use the speaker after assembly is fully and correctly done.
 It is recommended to place a cushion under the speaker section.
You can tighten the screws easily by placing the speaker section 
horizontally.

indicated by the speaker terminals on the rear of the powered subwoofer.
 DO NOT connect more than one speaker to one speaker terminal.
CAUTION
When installing the satellite speakers of TH-M45 and the front/surround speakers of TH-M55 on the wall;
