Hooking Up Speaker Cables

• The Speaker Connectors can accommodate up to 18 AWG speaker cables.
• It is recommended to leave about 150 cm (5 feet) of extra cable at the amplifier end to facilitate positioning and installation of the amplifier.
• Do not use staples, nails or other metal objects to secure the cables.
• You will get the best sound quality and the least amount of hum by keeping the cables away from other electrical wires and cables.
• Pay attention to connecting the polarity of the amplifier correctly with the speakers in each speaker group (speakers should be connected RED + with RED + amplifier connector, BLACK – with BLACK – amplifier connector).

WARNING

• Before connecting make sure that your amplifier is turned off.
• Do not let bare speaker wires touch each other or any metal part of this unit it may damage this amplifier and/or speakers. This may void your warranty.

Please refer to your speaker instruction manual for more information.

Connecting speaker cables
Speaker cables have 2 conductors. Each conductor should be connected to a separate speaker connector – mind the polarity while connecting. For each conductor:

1. Remove approximately 1 cm of insulation from the end of the conductor. Twist the bare wires firmly together.
2. The speaker connector block terminal is removable. Remove it by pulling it from the back to the outside of the device.
3. Using a small slot-type screwdriver unscrew the terminal block’s retaining screw which is placed on the top.
4. Insert the bare wires of the conductor into the block terminal’s hole.
5. Tighten the screw, making sure that it’s secure (the wire cannot be loose).

Hooking Up the Amplifier

1. Make sure the amplifier is turned off (the Power Switch is in the OFF, and the Power Cable is removed from the wall outlet).

2. Turn the Volume Regulator to MIN (max counterclockwise).

3. Using speaker cables connect your speakers to the SPEAKERS OUT.
   Check “Hooking Up Speaker Cables” for more details.

4. If you want to play music from audio source devices equipped with an analog output (CD player, Satellite tuner, Network streamer, Music player, Smartphone, Laptop etc.) choose the corresponding interconnect cables and connect the devices to the analog inputs (LINE IN, AUX IN).
   Check the table “External audio equipment connection options” for more details.
   WARNING
   The amplifier has one audio input path, which has two audio inputs connected in parallel (LINE IN and AUX IN) – if two audio source devices are connected and play sound simultaneously, their audio signals will be mixed.

5. Preamplifier Output (PRE OUT):
   this amplifier is equipped with the preamplifier output. Using an RCA-RCA interconnect you can connect to it an external amplification device (power amplifier, powered speakers, active subwoofer etc.) or a recording device (CD recorder etc.).
   Check „Preamplifier Output Connection (PRE OUT)” for more details.

6. Your amplifier is ready for operation.
   WARNING
   Only speakers within the range of impedance 4 – 8ohm may be connected to this amplifier. Connecting speakers outside this range may damage this amplifier and/or speakers. This may void your warranty.

7. External audio equipment connection options: The sockets and ports shown for external equipment and connection options may differ depending on the device.

Operation

1. Connect the Power Adapter to the amplifier and plug the Power Cable into the electrical outlet.

2. Turn on the amplifier – slide the Power Switch to the ON position.
   The Power LED Indicator will turn on.
   If it does not, it means that the amplifier is working under an abnormal condition (a protection mode) – turn off the power, unplug the Power Cable, and check whether some of the cables are not short-circuited.
   After fixing the cables turn the amplifier on.

3. Turn on your audio source and start playback.

4. Regulate the volume on the amplifier to adjust the level of sound.
   Note! Check “Additional Information” for other useful operating instructions.

WARNING
High volume levels may damage this amplifier and/or speakers. This may void your warranty.

VOLUME regulator:
Using the Volume Regulator you can adjust the sound volume from minimum (the knob – max counterclockwise) to maximum (the knob – max clockwise).

WARNING
Distortion and sound quality worsening may occur when the knob is in the maximum position. It may damage the amplifier and/or speakers. This may void your warranty.

TREBLE regulator:

• You can adjust treble output of the amplifier. The default: the knob is in the center position: the marker on the knob in the vertical position. Turn the knob counterclockwise (-) to decrease the amount of high frequencies.
• Turn the knob clockwise to increase the amount of high frequencies (+).

BASS regulator:

• You can adjust bass output of the amplifier. The default: the knob is in the center position: the marker on the knob in the vertical position. Turn the knob counterclockwise (-) to decrease the amount of low frequencies.
• Turn the knob clockwise (+) to increase the amount of low frequencies (+).

WARNING
Using the BASS / TREBLE regulators at high volume levels may damage this amplifier and/or speakers. This may void your warranty.

Preamplifier Output connection (PRE OUT):

• This amplifier is equipped with the preamplifier output, which allows connecting amplification or recording equipment such as a power amplifier, powered speakers, active subwoofer or a CD recorder.
• The audio signal from the preamplifier of this device is directed to the PRE OUT and its level is variable and controlled by the Volume Regulator.
• All sound adjustments (Bass / Treble) will affect the sound transmitted to the PRE OUT. The output to the SPEAKERS OUT is still active and it works simultaneously with the PRE OUT.

LIMITER:

• ON: Limiter is active. It prevents clipping of the amplifier. It is used to dynamically bring the levels of the loud audio signal parts down.
• OFF: Limiter is inactive.

Additional Information

Break-In

• Your TAGA Harmony amplifier sounds great immediately after it is taken out of the carton but as in all amplifiers, the internal components of this amplifier require a “break-in” period to reach its full sonic capabilities.
• During the “break-in” period it is recommended to operate the amplifier at moderate volume levels.
• The first level of the “break-in” is reached after approximately 10 hours of play.
• The optimal level of the “break-in” is reached after approximately 40 to 60 hours of play.

Turn off procedure
Make sure to turn off the amplifier first when powering down your system.

WARNING
If the amplifier was turned off even for a short period of time, you should wait at least 2 minutes before turning it back on. Do not turn it ON then OFF and then ON again in quick succession.

• Follow this procedure each time you turn your amplifier OFF / ON.
• This precaution will minimize the stress (high voltages) on internal components.

Noise floor
It is a normal phenomenon that an amplifier may produce some amount of noise (called noise floor or self-noise) which can be audible in speakers and headphones (in one or both channels).

Power transformer – Power filters and conditioners

• It is a normal phenomenon that the device’s power transformer may generate a certain amount of audible noise.
• Very loud operation of the power transformer may be caused by low quality of power supply (voltage surges etc.).
• In such a case, we suggest using a power filter or conditioner – you can also try to power this product from a different power line than other devices (e.g. from a power outlet in another room).
