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.

GaN-FET Driver

High-speed, loss-less switching is required to achieve pure amplification of accurately generated PWM signals. For this reason, this unit is provided with a high-speed GaN-FET Driver with super-low ON resistance.

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.
- Set the speaker selector knob to a position that corresponds to the connected speakers. (⇒ right)

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 Press the unit on/off button to the [ 一 / ] position.

• The power indicator lights up in blue.

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], turn the speaker selector knob or operate other controls 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.

Turning on/off the output correction function

Press [LAPC].

Each time you press the button:

LAPC indicator lights up	On
LAPC indicator goes off	Off

• When the SU-R1 is connected via the system control function, you can operate using the SU-R1's remote control.
• The output correction setting is applied separately to each speaker terminal option (A/B/A+B).
• Depending on the type of the connected speakers, the effect of the output correction function may be minimal.
• The corrected output remains in effect until you measure the characteristics again. When you use other speakers, redo the measurement.

Operations

1 Press the unit on/off button to the [=山/] position.

• The power indicator lights up in blue.

2 Turn the input selector knob.

Select a playback device and gain value.

ANALOG (dB) (-30/−20/−10/0)	Select an optimal setting for the connected device. (⇒ below)
DIGITAL	Select this setting when using the system control function.

3 Turn the speaker selector knob.

Select the speaker terminals from which audio will be output.

OFF	Does not output audio.
A	Outputs audio from the speakers connected to the A terminals.
B	Outputs audio from the speakers connected to the B terminals.
A+B	Outputs audio from the speakers connected to the A and B terminals.

4 Operatethe device to be used for playback.

Input selector knob setting during analogue input

• For normal operation, set the value to [0].
• For playback at low volume levels, lower the gain value of this unit by setting the input selector knob to [-30], [-20] or [-10] of [ANALOG (dB)]. This will minimise analogue/digital conversion errors that occur on this unit.

Using the system control function

You can operate this unit and the SU-R1 simultaneously with ease on the remote control of the SU-R1.

Preparation

① Connect this unit and the SU-R1 with cables for system control. ( 10)
② Set the input selector knob to [DIGITAL]. (⇒ 13)
③ Press the unit on/off button on this unit and the SU-R1 to the [ 一 / I ] position.
④ If "Digital Link" is set to "Off" on the SU-R1, change the setting to "On".

Switching this unit and the SU-R1 to on/standby simultaneously

• If you point the SU-R1's remote control at the SU-R1 and press [O] when this unit and the SU-R1 are in standby mode, this unit and the SU-R1 will be turned on simultaneously.
• If you point the SU-R1's remote control at the SU-R1 and press [O] when this unit and the SU-R1 are turned on, this unit and the SU-R1 will simultaneously enter standby mode.

- Measuring the characteristics of the amplifier and correcting its output

You can operate using the SU-R1's remote control. ( 13)

• For information on the operations of the SU-R1, please also refer to its operating instructions.
