Front Panel Features

1. Power Button: Pushing this button will manually supply power to the amplifier. The amplifier is designed to remain

in standby mode when not in use.

2. Standby: This LED (light emitting diode) will light blue when the D2120 is plugged into an A/C power supply.

3. Active: This yellow LED lights to indicate that the amplifier is in normal amplification mode.

4. Temp: This will light red to indicate that the left channel of the amplifier has overheated.

5. Fault: This will light red to indicate that the left channel of the amplifier is experiencing issues not related to

temperature/overheating.

6. Temp: This will light red to indicate that the right channel of the amplifier has overheated.

7. Fault: This will light red to indicate that the right channel of the amplifier is experiencing issues not related to

temperature/overheating.

1. Audio Source Input: The D2120 will accept any line level stereo audio signal. This can be from the preamp lineout of

a multi-source, multi-zone whole house system such as the NuVo Essentia E6G and Grand Concerto systems, or the audio output of any non-amplified source, such as an AM/FM tuner, CD player, or Satellite receiver.

2. Sensitivity Gain Control: Left and Right Channel Sensitivity trim pots allow the incoming signal to be increased or

decreased to maximize the potential output of the audio source.

3. Power Mode: This switch dictates how the amplifier responds to external triggers. The D2120 has 3 trigger methods:

Incoming audio signal, external voltage input, or the power button on the front of the amplifier.

4. Unit On: This provides a 12V trigger output when the amplifier is powered on. This can be used to turn on external

audio equipment, daisy chain multiple external amplifiers, or trigger a relay switching power strip.

6. Speaker Impedance: This switch sets the impedance stability at either four or eight ohms.

7. Speaker Output: The speaker output attaches to the amplifier via a modular plug and provides 120 Watts per

channel output at either 4 or 8 ohms.

8. AC Power: The D2120 is designed to plug into any AC power source.

Audio Source Inputs The D2120 amplifier features a single stereo RCA audio input 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 D2120’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 D2120 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 D2120 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 D2120. 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 D2120. For the Simplese system use a standard stereo RCA patch cable to connect the Simplese to the D2120. Fig. 2

TRIGGERON=+12V AUDIOOUTPUTII. Audio Sensitivity Control The D2120 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 iPod.

The D2120 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 the three options. Fig. 4 Left and Right Sensitivity Trims 11Setting 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 D2120 will turn on or off with the source equipment. Fig. 7 12IV. Trigger In This input (Fig. 8) is designed for a mono 1/8” plug to accept a trigger voltage coming in from an external source. Any voltage ranging from 3 to 30 volts, AC or DC, will cause the amplifier to turn on when the Power switch is in the Trigger mode. Fig. 8

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 D2120. 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 is you are powering a pair of 8 ohm speakers, or a single stereo speaker rated at 8 ohms. In installations where three or more 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. The power of the output will remain at 120 watts per channel. Fig. 10

The D2120 provides 120 watts of power per channel at four or eight ohms. It uses a modular plug (Fig. 11) that will accept up to 14 gauge, 4 conductor speaker wire. Stranded 4 conductor 16 gauge speaker wire is recommended. Fig. 11 The NV-D2120 amplifier is designed to run at a maximum load of 4 ohms. Prolonged operation at less than 4 ohms could cause the amplifier to overheat and damage its internal components. Overheating the amplifier due to an excessive load will void the warranty.Digital Power Amplifier Specifications Number of Channels Power Output Continuous Average Output Power 2 x 120W Two channels driven 20-20kHz @1% THD Rated Distortion (1/2 power) 0.02% Rated Impedance Switch Selectable 4 or 8 Ohms Damping Factor 50+ Frequency Response (20-20kHz) ±1 dB Power-On Modes Audio Power Trigger System Trigger Input 3-30 V AC or DC Unit On Output +12VDC @100mA Source Inputs Input Impedance 22k ohm Input Sensitivity for rated power .3-2V RMS Input Overload 2.4V RMS Power Requirements Power Supply Power Consumption both channels at maximum available output Power Consumption average operating conditions Power Consumption no signal Standby Power Consumption CE EMC CE LVD USA FCC ETL Canada Safety Listing (CAN/CSA E60065.00) Australia C-Tick ENERGY STAR ® Physical Specifications Unit Size Millimeters Unit Size Inches Shipping Size Millimeters Shipping Size Inches Unit Weight Kilograms Unit Weight Pounds Shipping Weight Kilograms Shipping Weight Pounds NuVo reserves the right to change specifications without notice.
