* NOTE ON USE

• INSTALLATION PRECAUTIONS

Using this receiver or other electronic equipment containing microprocessors simultaneously with a tuner or TV may result in noise in the sound or picture. If this should happen, take the following steps:

• Install the receiver as far as possible from the tuner or TV set.

• Keep the antenna lines of the tuner or TV as far as possible from the receiver's power cord and connection cables.

• This problem is especially frequent when using indoor anten nas. We recommend using outdoor antennas and 75 Q/ohms coaxial cables.

2 CONNECTIONS

Do not plug in the power cord until all connections have been completed.

Be sure to connect the left and right channels properly (left with left, right with right}. Insert the plugs securely. Incomplete connections will

result in the generation of noise.

Use the AC OUTLETS for audio equipment only. Do not use them for hair driers, etc.

NOTE:

The receiver cannot be used with MC cartridges directiy. Use a separate head amplifier or stepup transformer,

Turntable (MM cartridge)

A B

Note that binding pin plug cords together with power cords or placing them near a power transformer will result in the introduction of hum or other noise. If hum or other noise is produced when the ground wire is connected, disconnect it. Noise or humming may be generated if a connected component is used independently without turning the power of the AVR-2500 on, If this happens, turn on the power of the AVR'2500,

* Precautions when connecting speakers

If a speaker is placed near a TV or video monitor, the colors on the screen may be disturbed by the speaker's magnetism. If this should happen, move the speaker away to a position where it does not have this effect.

2-2 Speaker System Connections

• This receiver can accommodate connectiorrs of a total of eight speakers including two set of (front) main amplifier speakers (A and 8), one set of rear speakers, and one or two center speakers.

• Connect the speaker terminals with the speakers making sure that like polarities are matched (© with © , © with ©}. Mismatching of polarities will result in weak central sound, unclear orientation of the various instruments, and the sense of direction of the stereo being impaired.

• When making connections, take care that none of the indi vidual conductors of the speaker cord come in contact with adjacent terminals, with other speaker cord conductors, or with the rear panel.

Connecting the speaker terminals

• Speaker Impedance

• When speaker systems A and B are use separately, speakers with an impedance of from 6 to 16 Q/ohms can be connected.

• Be careful when using two pairs of main speakers (A + 8) at the same time, since use of speakers with an impedance out^e the .range of 12 to 16 Q /ohms will lead to damage.

• S'peakers with an impedance of 6 to 12 0/ohms can be connected for use as center and rear speakers.

• The protection circuit may operate or damage may occur when speakers with an impednce outside of the above range are used.

ANTENNA INSTALLATION

• Ш ANTENNA

The supplied FM antenna can be used inside wooden houses for receiving local FM stations and other strong FM signáis. Stretch out the ends of the antenna and mount the antenna on the wall or ceiling where optimum reception is achieved. A indoor FM antennas may not consistentiy ensure stabie recep tion, due to environment changes. In such cases, the indoor FM antenna should only be used temporarily until an outdoor FM antenna has been instaüed. When connecting an outdoor FM antenna, the use of 75 ohm coaxial cable (ЗС-2У, 5C-2V) is strongiy recommended.

. AM ANTENNA

Attach the supplied AM loop antenna even when using an outdoor AM antenna. Connect the leads to the AM and GNO termináis. Also use the AM terminals for connecting an outdoor AM antenna (when.making such a connection do not disconnect the AM loop antenna.) Adjust the loop antenna to obtain optimum recep tion, Where broadcast stations are distant and only weak signals are received, or where signals are blocked, it is best to tnstaii an outdoor AM antenna.

NOTES

• This receiver has a full back-up system. When the power is turned on, the INPUT SELECTOR buttons are set to the last mode set before the power was turned off.

• When using this receiver in close proximity to video equipment {TV, VCR, VOP, etc.), noise may be generated in AM broadcasts. To avoid this, keep the

receiver as far away from other video components as possible, or detach the AM loop antenna from the antenna holder and place it where noise is reduced. If the noise is not reduced, turn off the power of the video components when Üstening to AM broadcasts.

Note to CATV system instalier:

This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cabie ground shali be connected to the grounding system of the building, as close,to the point of cabie entry as practical.

2-4 Connecting the video components

To connect the video signal, connect using a 75 0/ohms video signal cable cord. Using an improper cable can result in a drop in sound quality.

2-5 Connecting the S-video terminals

• A note on the S input Jacks

The input selectors for the S inputs and pin jack inputs work in conjunction with each other.

» Precaution when using S-jacks

This receiver's S-jacks {input and output} and video pin jacks (input and output) have independent circuit structures, so that video signals input from the S-jacks are only output from the S-jack outputs and video signals input from the pin jacks are only output from the pin jack outputs. When connecting the receiver with equipment that is equipped with S-jacks, keep the above point in mind and make connections according to the equipment instruction manuals.
