DESCRIPTION

The XN3210 and XN3410 use an unregulated MOSFET power supply for superior sound and output wattage. In addition, a toroid-coil is used to transfer power with minimal performance loss due to heat. To avoid unwanted noise, a double-sided conformal printed circuit board with strategically placed components keeps AM RFI subdued.

All of the connections and controls for the XN3210 and XN3410 are conveniently located at the ends of the amplifier and labeled appropriately. To ensure the best possible electrical connections, the power, speaker, and RCA inputs are gold-plated. An additional benefit of the XN3410 is the ability to create a 2, 3, or 4 channel amplified system with a flip of a switch (see Application section). In the event of component failure or a short circuit, the XN3210 and XN3410 incorporate safe guards and outboard ATC fuses to prevent damage to the amplifier.

INPUT CONNECTIONS AND AUDIO CONTROLS

The front panel of the XN3410 and XN3210 contain both connections for RCA and speaker level inputs, along with the audio controls as shown below.

The RCA connections are gold plated for optimum performance and low signal loss. The RCA connectors are labeled CH1 (front left), CH2 (front right) [for XN3410: CH3 (rear left), and CH4 (rear right)]. In applications where RCA signals are not present, the speaker level output from the head unit can be used. (Use one or the other input, not both.)

• Gain Controls: For the XN3410, separate CH1/2 and CH3/4 gain controls allow you to set the nominal operating level of the amplifier. The amplifier's input range, 200mV to 6.0V for RCA inputs and 500mV to 13V for speaker level inputs, can accommodate input levels from virtually any head unit.
• Bass Boost: The amplifier features a "high-Q" (i.e. narrow frequency band) Bass Boost circuit. It acts much like an equalizer with an adjustable gain from 0 to +15dB fixed at 45Hz. Use this feature to tune low-frequency audio response to compensate for a less than ideal subwoofer enclosure design. The added boost produces rich, full bass tones that are normally difficult to reproduce in the marine audio environment.

NOTE: Bass Boost setting should only be used for subwoofer applications.

• Source Select (XN3410 only)

2CH BASS: Uses CH1/2 inputs and has output from all 4 channels with Bass Boost.

2CH: Uses CH1/2 inputs and has output from all 4 channels. The Bass Boost will work only on CH1/2 and have no effect on CH3/4.

4CH: Uses all 4 channel inputs and has output from all 4 channels. The Bass Boost will work only on CH1/2 and have no effect on CH3/4.

- Output Mode Selector Switch: CH 1/2 and CH 3/4 (XN3410 only)

STEREO: Full left and right stereo operation.

CH1Mono / CH2 Mono: Single channel input for bridged operation. This is especially useful in high-powered systems. (Uses CH2 and CH4 inputs.)

CH1/2 Mono / CH3/4 Mono: Allows for a stereo input to be summed into a mono output.

- CH1/2 FREQ / CH3/4 FREQ (XN3410 only) The CH1/2 crossover frequencies are adjustable from 55Hz to 550Hz. While CH3/4 crossover frequencies are adjustable from 55Hz to 5500Hz (via the Frequency Range Multiplier) for a wider range of crossover points. Use this feature along with your speaker manufacturer's recommended crossover frequencies to quickly design a more advanced system.

NOTE: If either of the Crossover Mode Switches is set to OFF, varying the frequency control will have no effect.

- CH1/2 Filter / CH3/4 Filter (XN3410 only) A filter is activated by sliding the CH1/2 and CH3/4 filter switch to either HP = High Pass or LP = Low Pass. CH1/2 is fully adjustable from 55-550Hz (via CH1/2 Freq) and CH3/4 is fully adjustable from 55-5500Hz (via CH3/4 Frequency and Frequency Range Multiplier). Use this feature along with your speaker manufacture's recommended crossover frequencies to design a more advanced system.

XN3210 - Electrical Connection

INSTALLATION

This section suggests Mounting and Wiring Precautions for installing the Clarion XN3210 and/or XN3410 amplifier(s). If you do not possess the necessary tools and installation experience, do not attempt to install these amplifiers. Instead, contact your local Clarion Marine Audio dealer to perform the installation.

MOUNTING PRECAUTIONS

Prior to mounting the amplifier, make sure it is safe to mount the amplifier in that location. Failure to do so can result in serious damage to the boat. In addition, stainless steel hardware should be used to mount the amplifier and additional accessories. When possible, use a nut and bolt with a lock washer to secure the amplifier. Extra care and attention is necessary in marine installations due to the uncertainty of water conditions.

Additional precautions and suggestions:

1. For the most efficient cooling, mount the amplifier so cool air runs along the length of the heat sink, rather than across them. To increase air movement and circulation, a cooling fan can be installed.
2. Mount the amplifier on a rigid surface; avoid mounting to subwoofer enclosures or areas prone to vibration.
3. Prior to drilling and holes, make sure the proposed mounting holes will not cut into the fuel tank, fuel lines, electrical wiring, or through the boat.
4. Do not mount the amplifier where it is susceptible to water.

WIRING PRECAUTIONS

Read all of the wiring precautions prior to making any connections. If you are unsure and/or don't have the necessary installation hardware, contact your local Clarion Marine Audio dealer to perform the installation.

1. Before you begin the installation, make sure the source unit Power switch is in the OFF position.
2. Disconnect the negative (-) lead of the battery (or batteries) before making any power connections.
3. When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.
4. A good ground is critical for the performance of the amplifier. A ground wire should be run directly from the battery to the amplifier. Use black insulated 10-gauge or larger wire for the amplifier's ground (-) power lead.
5. Add an additional fuse holder and fuse at the positive (+) terminal of the battery. The fuse rating should equal the total current consumption at full output of the amplifier(s). Use red insulated 10-gauge or larger wire for the amplifier's positive (+) power lead. Do not install the fuse until the complete installation has been performed.

6. When replacing the amplifier's fuse, always use one having the same amperage rating. Substituting a higher rated fuse or a slow-blow type can result in serious damage to the amplifier.

7. When creating passage holes for power cables, RCA's cables, and speaker wires, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short circuit.

8. Extra cable can cause signal loss and act as an "antenna" for noise. Use only high-quality RCA cables that are no longer than necessary.
9. In multiple amplifier systems, it is recommended to use a relay on the remote turn-on lead of the radio.

NOTE: Chart values based on 4 Ohm speakers.

The amplifier can be configured for a mixed-mode operation. The table provides component values to create a 6dB per octave crossover at specified frequencies. Use components that have a +5% tolerance and capacitors rated at 100V. NOTE: Choose the same frequency for both LP and HP crossovers. Do not overlap frequencies, as this may damage the amplifier.

SETTING THE GAIN

After completing the installation, follow these steps to set the Gain Control and then perform the Final System Check.

1. Turn the Gain Control all the way counter-clockwise.
2. Turn the ON/OFF Switch on the source units to the ON position. Set all Tone or Equalization Controls to "flat" positions and turn Loudness off.
3. Play a CD, set the Volume Control at 75% of full level.
   NOTE: If the system uses an equalizer, set its frequency controls to "flat" positions.
4. Slowly increase the Gain Control. Stop when you hear a slight distortion of audio.

SETTING THE CROSSOVER

The Clarion XN3210 and XN3410 feature fully adjustable high and low pass crossovers. To set the crossover, follow these steps.

1. Using the X-Over Mode Switch, select the desired mode: LP for Low Pass, HP for High Pass or OFF for Full Range.
2. Using the Freq (Hz) Selection Control, select the desired frequency. If the desired frequency exceeds the range of the Freq (Hz) Selection Control, press the Crossover Frequency Multiplier Switch to increase the value by a multiplier of 10.

3. For example, 55Hz × 10 = 550Hz or 550Hz × 10 = 5.5kHz .

4. Repeat steps 1 and 2 for both the CH1/CH2 and CH3/CH4 crossovers on the XN3410.

SETTING THE SUBWOOFER BASS BOOST

1. Initially set the Bass Boost control to its full left position (i.e. 0dB).
2. Listen to a variety of music styles (e.g. Rock, Rap, etc.) and slowly increase the Bass Boost control until a noticeable increase in low bass response is perceived.
3. Slowly adjust the Bass Boost control (up or down) to realize the best bass response.

CAUTION: If you hear a "pop" (due to speaker over-excursion), lower the Bass Boost to prevent speaker damage. If the system sounds muddy and distorted (due to amplifier clipping), lower Bass Boost to avoid shutdown from overheating.

FINAL SYSTEM CHECK

1. Turn on the source unit. After a two-second delay, slowly increase the Volume Control and listen to the audio. If you hear any noise, static, distortion or no sound at all, check the connections and refer to the Troubleshooting section. Depending on your system design, the levels may become quite loud even at low Volume Control settings. Until you get an "audio feel" of the system's power, use care when adjusting controls.
2. Turn the Balance Controls to their extreme positions and listen to the results. Audio imaging should match control settings (audio from the left speaker when balance is left).
3. Increase the volume and verify that the amplifier reproduces audio (at full frequencies) without distortion. If you hear distortion, check the connections and verify that the Gain Control is set correctly. Another possibility is damaged speakers or under-powered speakers. Refer to the Troubleshooting section for additional help.
