Frequently Asked Questions - Syn Tech 2.100 Macrom

How to install the Syn Tech 2.100 amplifier in my car?

We recommend having the amplifier installed by an authorized MACROM dealer. First connect the ground wire (GND) to a clean chassis point, then +BATT to the battery via a fuse, and REMOTE to the remote output of the car stereo. Finally, connect the speakers and RCA inputs.

What types of filters are available on this amplifier?

The amplifier has a filter selector with three modes: Flat (full range), Low-Pass (low-pass), and High-Pass (high-pass). The cutoff frequency is continuously adjustable from 30 to 600 Hz with a slope of 12 dB/octave.

How to adjust the input sensitivity (gain)?

First set the volume of your car stereo to about 75% of maximum output. Then turn the amplifier's gain control until you achieve the maximum sound level without distortion. Sensitivity ranges from 200 mV to 4 V.

What does the Check Control (LED) indicator mean?

The Check Control LED indicates the amplifier status: white = off, green = normal operation, red = protection mode (overheat, overload, or short circuit). If red, turn off and on the car stereo after resolving the issue.

Can I use the amplifier in three-channel configuration?

Yes, the amplifier can be configured in 3 channels (stereo for front speakers and one bridged channel for a subwoofer). The total impedance must not drop below 2 ohms. Refer to the wiring diagram in the manual.

What is the minimum speaker impedance?

In stereo mode, the minimum impedance is 1 ohm per channel. In bridged mono mode, it is 2 ohms. Make sure to respect these limits to avoid protection mode.

How to connect the external bass control (EBC)?

The EBC (External Bass Control) port allows connecting an optional controller to adjust the bass level from 0 dB to -40 dB. Activate the corresponding selector (mark 17) and connect the controller to the port (mark 18).

Which fuses to use and where are they located?

The amplifier is equipped with fuses located near the power connector (mark 12). They must be replaced with fuses of the same rating to avoid damaging the device. Check the value indicated on the original fuse.

What to do if the amplifier overheats?

If the amplifier goes into protection due to overheating (red LED), check the airflow around the device. Ensure it is not obstructed and that ventilation is sufficient. Once cooled down, the device resumes normal operation.

Can I use this amplifier with an audio source other than a car stereo?

Yes, thanks to the RCA inputs, you can connect any audio source with a preamp output (MP3 player, phone, etc.). Adjust the input sensitivity accordingly (200 mV to 4 V) and use adapters if necessary.

CONTROLS AND INDICATORS

1 · RCA input connectors: To connect the Pre output leads of the main unit to the amplifier input. These inputs control the final stages.
2 · Adjustment of the gain of the Input: Adjusts input sensitivity of amplifier, which can vary between 200mV and 4V .

To adjust sensitivity, proceed as follows:

a)Set the volume control of your unit to 3/4 of its maximum output

b) Adjust the amplifier input gain controls until the maximum possible acoustic pressure has been obtained without any distortion.

3 - Stereo/Mono switch: changes the output mode of the amplifier between Stereo and Mono. If Mono is selected, the corresponding Left (mono) input is used to operate the amplifier.

4 - Crossover switch: selects the output mode of the amplifier by activating the Low-pass or High-pass filter.

a) Flat: the amplifier will reproduce the complete audio range in relation to the signal applied to the input.

b)Low-pass: activation of the low-pass filter, i.e. determination of the finishing-point of the low frequencies present at the outputs.

c)High-pass: activation of the low-pass filter, i.e. determination of the starting-point of the high frequencies present at the outputs.

5 · Continuous adjustment/control of the Low-Pass or High-Pass frequencies: once the low-pass or high-pass filter is inserted, the crossover frequency can be

adjusted in continuous mode between 30Hz and 600Hz .

CONTROLS AND INDICATORS

1. Speaker connectors: Outputs for connecting the loudspeakers.

The amplifier allows the loudspeakers to be connected with a minimum impedance of 2 Ohm for a channel in stereo configuration, and with an impedance of 4 Ohm for a "bridged" mono connection.

If the 3 channel configuration is to be used, the total impedance should not exceed the minimum value of 2 Ohm.

Make sure that the polarity of the connection between the loudspeakers is correct. Do not allow inadequately insulated leads to come into contact with Ground, any metallic parts of the car, or with each other.

10 · Fuses: When replacing fuses, make sure that they are replaced with fuses of the same ampere rating. Use of the wrong type of fuse could seriously damage the components.
11 · + BATT connector: Connect the positive "+" of the battery directly, by means of a fuse located nearby, and use a lead having a sufficiently large cross-section to allow passage of the current. Do not connect this terminal to the car's own electrical circuit.
12 - REMOTE-ON connector: Connect this to the remote-on start-up output lead (remote starting switch) or to the automatic antenna wire running from the main unit. It will now be possible to turn the amplifier on and off from the main unit.
13 · GND connector: Attach this Ground connector, using a lead of adequate section, to a clean point on any metallic part of the car chassis, if possible to an already-installed screw.

Never attach this clamp directly to the negative point of the battery, which could give rise to an unpleasant buzzing noise while the car is being driven.

14 Check control indicator: This LED indicates the amplifier functioning status.

WHITE: The unit is switched off

GREEN: The amplifier is functioning perfectly

RED: the unit is in a state of protection.

The amplifier is equipped with three protection devices:

• Overheating: If errors have been made during installation, and the amplifier overheats, the unit will enter into a state of protection before any damage can occur. Once the temperature returns to normal and the errors have been rectified, the unit will automatically start to function normally once again.
• Overloading: If several loudspeakers have been connected to the amplifier and the total impedance drops below the 1 Ohm limit that it can handle, the amplifier goes into a state of protection. The main unit will have to be switched off and on again in order to restore the amplifier to normal functioning.
• Short circuit in an output: In the case of a short circuit in the loudspeaker outputs, the unit will go into a state of protection to avoid serious damage to the final transistors. Normal functioning will be restored when the short circuit has been dealt with and the main unit switched on again.
