Danger

Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures:

DURATION PER DAY (HOURS)	8	6	4	3	2	1
SOUND LEVEL (dB)	90	93	95	97	100	103

According to OSHA, any exposure in the above permissible limits could result in some hearing loss. Ear plugs or protectors in the ear canal or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss. If exposure in excess of the limits as put forth above, to insure against potentially harmful exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of inducing high sound pressure levels, such as this amplification system, be protected by hearing protectors while this unit is in operation.

CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE CHASSIS. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

Back Panel Features

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.
5. Trigger In: This voltage trigger input allows the D2120 to power up whenever a voltage of 3-30 volts AC or DC is present.
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.

I. 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

INPUT L SENSITIVITY O=BY = 1.0RMS R LEFT 0 -12 RIGHT +6 -12 AMPLIFIER USE ONLY NoNo NV-T2PAS POWERED ANTENZA SY STEIN AUX IN AUDIO OUT TRIGGER ON+12V AUDIO OUTPUT

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.

II. 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

INPUT L R SENSITIVITY OdBV = 1.0RMS LEFT 0 -12 RIGHT 0 +6 -12 AMF LIFIER Left and Right Sensitivity Trims

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.

III. Power Mode

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

SENSITIVITY OdBV = 1.0RMS POWER MODE TRIGGER IN 3-30 VOLTS AC OR DC UNIT ON AMPLIFIER

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 SENSITIVITY OdBV = 1.0RMS POWER MODE TRIGGER IN 3-30 VOLTS AC OR DC LEFT 0 +6 -12 RIGHT 0 +6 -12 AUDIO TRIGGER +12VDC 100mA UNIT ON AMPLIFIER

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 SENSITIVITY OdBV = 1.0RMS POWER MODE TRIGGER IN 3-30 VOLTS AC OR DC LEFT 0 +6 -12 RIGHT 0 +6 -12 AUDIO TRIGGER +12VDC 100mA UNIT ON AMPLIFIER

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.

IV. 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.

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 D2120.

SENSITIVITY OdBV = 1.0RMS POWER MODE TRIGGER IN 3-30 VOLTS AC OR DC UNIT ON AMPLIFIER

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 SPEAKER IMPEDANCE 4 OHM 8 OHM OUTPUT POWER 8 OHM: 120W X 2 4 OHM: 120W X 2 SPEAKER

VII. Speaker Outputs

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

SPEAKER IMPEDANCE 4 OHM 8 OHM OUTPUT POWER 8 OHM: 120W X 2 4 OHM: 120W X 2 SPEAKER

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.
