Precautions

On safety

• Operate the unit only on 120 V AC, 60 Hz.
- The unit is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the unit itself has been turned off.
- Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by the plug. Never pull the cord itself.
- Should any solid object or liquid fall into the unit, unplug the unit and have it checked by qualified personnel before operating it any further.

On Installation

Place the unit in a location with adequate air circulation to prevent internal heat build-up.

If you have any question or problem concerning your unit, please consult your nearest Sony dealer.

Frequency Coverage of Each Equalizer Control

Specifications

60 Hz: Use to boost or cut the bass.

150 Hz: This control governs the low-middle range and greatly influences the overall characteristics of the sound.

400 Hz: Use to adjust the power, spaciousness and warmth of the sound.

1 kHz: Use to provide more presence for vocals.

2.4 kHz: Use to boost a brighter sound and to reduce stridency.

6 kHz: This control effects the treble. Use to adjust the brightness of the sound and to reduce high frequency noise, such as tape hiss.

14 kHz: This control adjusts the general atmosphere rather than the sound itself. Use to highlight the delicate quality of instrumental sound.

Checking the equalization results

Press EQUALIZATION again to OFF (released position).

The equalizer circuit is bypassed, and you can hear the sound without equalization.

By switching EQUALIZATION ON and OFF, compare the results.

The spectrum analyzer can be used to visually confirm the need for, and effect of, equalizer adjustment.

Troubleshooting Guide

Before going through the check list below, first refer back to the connections and operating procedures. Should any problem persist after you have made these checks, consult your nearest Sony service facility.

Symptom	Cause
No audio even when the POWER switch is turned on.	The power cord is disconnected.The connecting cord is disconnected.The TAPE switch setting is not correct.
No equalization	The EQUALIZATION switch is set to OFF (the indicator is off).Connections are not made properly.
The program source connected to the amplifier cannot be recorded.	The TAPE switch is set to ON.

Equalizing an Input Source

	1 When the equalizer is connected to TAPE jacks of the amplifier	2 Select the input signal to be equalized on the equalizer.For playback output from the amplifier.	3 Select the desired input source with the amplifier, and play the program source.	4 Adjust the amplifier volume.	5
	2 For playback output from the cassette deck connected to the equalizer,	3 Play back the tape on the deck			6

Connections

Connecting with an amplifier not equipped with connectors for a graphic equalizer. The graphic equalizer can be used only with an amplifier hanging the tape monitor function. SEQ-400 Cassette Deck With this connection, you can record or dub the equatified sound on the cassette deck amplifier.

Connection Notes • Connect the AC power cord last. Make sure POWER is OFF. • Fully insert cable connectors into jacks. Loose connections may cause hum or noise. • The red jacks are for the right-channel (R) connectors and the white jacks are for the left channel (L). White L A Red R
