I. Audio Source Inputs

The D460 amplifier features dual stereo RCA audio inputs designed to accept a line level audio signal. Most audio equipment is equipped with a

stereo RCA output that allows the audio signal to be taken directly to the D460’s audio input. This is accomplished using a standard stereo audio

cable with left and right audio jacks on each end (Fig. 1).

Fig. 1

The D460 is a great complement to any NuVo Multi Room Audio System, where extra amplification may be desired for a particular zone. Zone 4 on

the Simplese audio system has a fixed and variable RCA stereo audio output. Zones 1 & 2 on the Essentia E6G have fixed and variable 3.5mm stereo

audio outputs, and all zones on the Grand Concerto have fixed and variable 3.5mm stereo audio outputs. To add the D460 to one of these systems,

use a 3.5mm to Stereo RCA adapter cable to pass the audio signal from the NuVo Grand Concerto or Essentia E6G to the D460. Connect the 3.5mm

end into the variable 3.5mm output for the chosen zone (Fig. 2) on the Grand Concerto or Essentia E6G, and connect the left and right RCA’s into the

input on the D460. For the Simplese system use a standard stereo RCA patch cable to connect the Simplese to the D460.

II. Audio Sensitivity Control

The D460 allows the flexibility of controlling the left and right channel gains for the incoming audio signal. The sensitivity allows a control of -12 dB

up to +6 dB, and is an excellent tool for maximizing the full output potential of your source equipment (Fig. 3).

Fig. 3

To best utilize this feature, set the volume for the source at its fullest output level. Then adjust the left and right sensitivity trims on the amplifier to

allow the fullest possible output from the speakers without distortion.

+6 or a counter-clockwise turn is used to reduce the gain. This would be the preferred setting for a distributed audio system with variable preamp

line outputs, such as any of the NuVo systems. Reducing the gain can also be useful for limiting the maximum power going to the speakers.

O or straight vertically is the factory default. This is the preferred setting for an audio signal from a preamp, such as a distributed audio system

with a fixed preamp line output, or the audio output of a music server or CD player.

-12 or a clockwise turn is a high gain position. This is typically used when the incoming audio signal is weak, such as a portable CD player or cable

tv box.

III. Power Mode

The D460 provides three basic methods for supplying power to the amplifier. This can be accomplished by simply pushing the Power button on the

front of the unit, by sensing an incoming audio signal, or by supplying a 3-30 volt AC or DC current. The Power Mode switch on the back of the

amplifier (Fig. 4) sets the amplifier to respond to any of these three options. Note that the Power Mode is set independently for Amplifier A and B.

Fig. 4

Left and Right

Sensitivity Trims

Setting the power mode switch to the left in the Audio mode (Fig. 5) sets the amplifier to respond to the presence of an audio signal. If you are

triggering the amplifier in this way, you should expect a slight delay before it turns on.

When the audio signal is removed, the amplifier will remain on for approximately three minutes after the incoming audio signal has ended before

the unit turns off. This will prevent the unit from inadvertently turning off when the audio signal is very low or stops temporarily.

Fig. 5

When setting the power mode switch to the center (Fig. 6), the amplifier will turn on or off only when the Power button on the front of the

amplifier is pressed.

Fig. 6

Setting the power mode switch to the right (Fig. 7) sets the amplifier to respond to an incoming voltage. This voltage can be AC or DC and anything

from 3-30 volts. This is very useful in conjunction with a multiroom audio system or preamp that has a voltage trigger output. In this mode the

D460 will turn on or off with the source equipment.

Fig. 7

IV. Trigger In

This input (Fig. 8) is designed for a mono 3.5mm plug to accept a trigger voltage coming in from an external source.

Any voltage ranging from 3-30 volts, AC or DC, will cause the amplifier to turn on when the Power switch is in the Trigger mode.

Fig. 8

V. Unit On

This output (Fig. 9) provides a constant 12 volts DC when the amplifier is powered on. This is useful for powering on external equipment with the

D460.

Fig. 9

VI. Speaker Impedance

This switch (Fig. 10) allows for the adjusting of the impedance of the amplifier. By default the amplifier will be set at 8 ohms. This is fine if you are

powering a pair of 8 ohm speakers, or a single stereo speaker rated at 8 ohms. In installations where 2 pairs of 8 ohm speakers will be used, or a

pair of 4 ohm speakers are being utilized, the impedance of the amplifier should be set to 4 ohms.
