Frequently Asked Questions - SU-C700EB TECHNICS

How do I connect speakers to the SU-C700EB?

Turn the speaker terminal knobs counterclockwise to loosen, insert the stripped wire ends into the holes, then tighten the knobs. Ensure correct polarity (+ and -) and avoid short-circuiting. Refer to the manual for proper gauge.

How can I connect a turntable?

Use the PHONO input for MM cartridges. Connect the turntable's audio cable to the PHONO jacks and the ground wire to the PHONO EARTH terminal. If your turntable has a built-in phono preamp, connect it to the LINE IN instead.

What is LAPC and how do I use it?

LAPC (Load Adaptive Phase Calibration) optimizes amplifier output based on speaker impedance. To use, press and hold the LAPC button on the remote until the LAPC indicator blinks. A test tone will play for about 4 minutes. After measurement, LAPC indicator lights up to confirm correction is active. Press LAPC to toggle on/off.

How do I reset the amplifier to factory defaults?

With the unit turned off, press and hold [AMP ⏻] on the remote, then raise the power switch lever on the unit to the ON position. Continue holding until the PC and COAX2 indicators blink twice. Release the button.

Why is there no sound?

Check all connections (speakers, input cables). Ensure the correct input is selected. Verify the volume is not muted or set too low. If the headphone jack is plugged in, speakers are disabled. For digital inputs, confirm the source outputs LPCM (the amplifier does not support multi-channel formats).

How do I change the remote control code?

Point the remote at the amplifier and press and hold [OK] plus a numeric button ([1] or [2]) for at least 4 seconds. The PC and COAX2 indicators will blink for about 10 seconds to confirm. Use this if other devices respond to the remote.

How do I connect a PC via USB?

Download and install the dedicated USB driver (Windows) and the Technics Audio Player app from the Technics support website. Connect the PC to the PC USB port on the amplifier using a USB cable. Select PC input on the amplifier and start playback. The amplifier supports USB Audio Class 2.0 asynchronous mode for high-quality audio.

What is the auto off function and how can I disable it?

The auto off function puts the amplifier into standby after approximately 20 minutes of no audio signal and no operation. To disable, press and hold [MUTE] until the PHONO indicator blinks, then press [MUTE] repeatedly until OPT indicator blinks (off). Press [VOL -] to exit.

How do I use the system control function with the ST-C700?

Connect the ST-C700 to the CONTROL1 terminal using the supplied system connection cable, and connect a coaxial digital cable from the ST-C700's COAXIAL OUT to the amplifier's COAX1 IN. Then you can power on/off both units simultaneously and the input automatically switches to COAX1 when playing from the ST-C700.

The amplifier becomes very hot. Is this normal?

The amplifier generates heat during normal operation, especially at high volume levels. Ensure adequate ventilation around the unit. Do not place objects on top. If it shuts off automatically, it may be due to overheating protection. Allow it to cool for about 3 minutes before turning on again. If overheating persists, reduce volume or check speaker impedance.

■ Features of this unit

This unit offers the following features:

Full-digital amplifier with a high-precision jitter reduction circuit and PWM conversion circuit

This unit is a full-digital amplifier. Its specially-designed jitter reduction circuit and high-precision PWM conversion circuit eliminate distortion, noise, and jitter.

LAPC (Load Adaptive Phase Calibration)

Adaptive processing of speaker impedance flattens frequency amplitude and phase characteristics. The result is the reproduction of sound with rich spatial expression.

High-speed and lower noise linear power supply

The combination of a large-current Schottky-barrier diode, a rectifier circuit with a large storage capacitor, and a stabilized power supply circuit achieves remarkably superior power supply that is both low-noise and plentiful.

■ Recommended devices

We recommend using Technics devices (optional) for superior audio quality.

Measuring the characteristics of the amplifier and correcting its output

To optimise the audio output, you can measure the amplifier characteristics and correct its output when it is connected to the speakers.

- Disconnect the headphones. If you connect them during amplifier characteristic measurement or amplifier output correction, it will be cancelled.

Test tone emitted during measurement

To ensure the measurement accuracy, the speakers output a test tone at regular intervals. (For approximately 4 minutes)

It is not possible to change the volume of the audio being output while the measurement is in progress.

1 Raise the power switch lever of this unit to the [∅/I] position.
2 Press and hold [LAPC] until the LAPC indicator on this unit starts to blink.

- This unit will start measuring the characteristics of the amplifier. Check that a test tone is output from both the left and right speakers.

- If you press [LAPC] while the measurement is in progress, it will be cancelled. The LAPC indicator on this unit will go off.

- When the measurement is complete, amplifier output correction will be automatically turned on. The LAPC indicator on this unit will light up.
