Connecting to a Power Amplifer

Connecting to a Power Amplifier

There are two different ways the D150 may be oper-

ated in an audio system. The first way as the Main 

Audio Preamplifier connected directly to a Power 

Amplifier, instructions on this page. The second way 

as a Digital to Analog Converter with Input Switching 

connecting to an Analog Preamplifier, instructions on 

the next page.

The D150 has the ability to automatically switch 

power On/Off to Source Components via the Power 

Control connections. The Data Port Connections allow 

for the remote operation of basic functions using the 

D150 Remote Control. With an external sensor con-

nected to the D150, remote control operation of the 

system is possible from another room and/or when the 

D150 is located in a cabinet with the doors closed.

The connection instructions below, together with 

the D150 Connection Diagram located on the separate 

folded sheet “

Mc1A

”, is an example of a typical audio 

system. Your system may vary from this, however the 

actual components would be connected in a similar 

manner. For additional information refer to “Connec-

tor and Cable Information” on page 4.

Note: The Power Amplifier may be connected to the 

D150 Balanced or Unbalanced Outputs.

Power Control Connections:

1. Connect a Control Cable from the D150 POWER 

CONTROL OUT Jack to the Power Control In on 

the SACD/CD Transport.

2. Connect a Control Cable from the SACD/CD 

Transport Power Control Out Jack to the Tuner 

Power Control In Jack.

3. Connect a Control Cable from the Tuner Power 

Control Out Jack to the SACD/CD Player Power 

Control In Jack.

4. Connect a Control Cable from the SACD/CD Play-

er Power Control Out Jack to the Power Amplifier 

Power Control In Jack.

Note: If two Power Amplifiers are used, connect the 

Power Control Output of the first Amplifier to 

the Power Control Input on the second Ampli-

fier.

5. Connect any additional Components in a similar 

manner, as outlined in steps 1 thru 4.

Sensor Connection:

6. Optionally, connect the external Sensor to the 

D150 IR Input Connector.

Audio Connections:

7. Connect balanced audio cables from the D150 

VARIABLE AUDIO OUTPUT (R&L) connec

-

tors to the balanced Input connectors on the Power 

Amplifier.

Note: If two Power Amplifiers are used, connect 

the unbalanced VARIABLE AUDIO OUTPUT 

(L&R) to the unbalanced Inputs on the second 

Amplifier.

Digital Audio Connections:

8. Connect a Digital DIN Cable from the D150 DIGI-

TAL DIN INPUT Jack to the SACD/CD Transport 

Digital Audio DIN Output Jack.

9. Connect a Digital Coaxial Cable from the D150 

DIGITAL AUDIO COAXIAL IN 1 Jack to the 

Tuner Digital Coaxial Output Jack.

10. Connect a Digital Optical Cable from the D150 

DIGITAL AUDIO OPTICAL IN 1 Jack to the 

SACD/CD Player Digital Optical Output Jack.

11. Connect a USB cable with (type A to type B) con

-

nectors from the D150 DIGITAL AUDIO INPUT 

USB to the Computer USB connector.

12. Connect any additional Components in a similar 

manner, as outlined in steps 8 thru 11.

AC Power Cords Connections:

13. Connect the D150 and any remaining components’ 

AC Power Cords to a live AC outlet as illustrated.
