Frequently Asked Questions - Syn Power 2.050x Macrom

What is the power of the Macrom Syn Power 2.050x amplifier?

The RMS power is 2x55 W at 4 ohms, 2x80 W at 2 ohms, and 1x160 W in bridged mono at 4 ohms. In dynamic mode (14.4 V), it reaches 2x60 W, 2x100 W, and 1x200 W respectively.

How to adjust input sensitivity (gain)?

Set the head unit volume to 3/4 of maximum, then turn the amplifier gain control until you achieve the highest sound level without distortion.

What types of filters are available?

Crossover selector with Flat (full-range), Low-Pass, and High-Pass modes. The cutoff frequency is adjustable from 30 to 600 Hz.

How to connect the amplifier in mono mode?

Set the Stereo/Mono selector to Mono. Use the Left input to drive the amplifier. Ensure that the speaker impedance is at least 4 ohms in bridged mono.

What does the Check Control indicator mean?

White LED: unit off. Green LED: normal operation. Red LED: protection state (overheating, overload, or short-circuit). The amplifier automatically reactivates after the problem is resolved.

What are the wiring precautions?

Connect the +BATT wire to the battery with a nearby fuse, the REMOTE to the remote turn-on, and the ground (GND) to a clean chassis point. Use appropriate gauge cables and avoid connecting GND directly to the battery negative.

What type of fuse to use?

Always replace fuses with fuses of the same rating. Using fuses of different ratings can seriously damage the device.

What is the minimum speaker impedance?

In stereo, 2 ohms per channel. In bridged mono, 4 ohms. For a 3-channel configuration, the total impedance must not drop below 2 ohms.

How to avoid overheating?

Install the amplifier in a well-ventilated area to ensure proper air circulation and heat dissipation. If overheating occurs, the device enters protection and will resume normal operation after cooling.

Can I repair the amplifier myself?

It is not recommended to repair the device yourself. Entrust any repairs to an authorized MACROM dealer or service center.

INTRODUCTION

Macrom, who strive continually to achieve the ultimate in sound quality, have traditionally been a synonym for the very best in European sound and music reproduction. The fact that you have chosen this product means that you share our opinion. After reading this manual you will be in an even better position to appreciate all the advanced features in this new Amplifier. This Amplifier incorporates an exceptional set of technical features, and for this reason all signal sources, loudspeakers and interconnecting elements must also be of the very highest quality. We recommend the use of Macrom high quality main subassemblies, electronic crossovers, loudspeaker systems, connecting leads and accessories. Similarly, because integration of these products is an extremely complex task, we advise you to leave the installation of this amplifier to your authorised MACROM dealer.

This Amplifier has no commands or controls that can be adjusted by the user, so read this manual very carefully, to familiarise yourself with the special features and functions of your new MACROM product. If in any doubt, contact your authorised MACROM dealer.

PRECAUTIONS

1. Just one faulty connection could damage the unit, so read the connection instructions provided in this manual very carefully.
2. Connect the battery lead to the (+) battery terminal last of all, and only after having completed and checked all the other connections.
3. Take care to install the amplifier in a position where both good air circulation and heat dissipation are guaranteed.
4. The fuses must always be replaced with fuses of identical ampere rating in order to prevent serious damage to the components. You should also first have the voltage regulator of your car checked. Never attempt to repair the unit yourself. Entrust any necessary repairs to a MACROM distributor or your local MACROM service centre.
5. To ensure the highest possible performance from this unit, try to obtain a temperature of between -10^ and +60^ inside your car before switching on the amplifier.

FEATURES

• Input mode switch
• Flat, low-pass or high-pass filter switch
  • Continuous frequency control
  • Continuous sensitivity control
• Current feed with Mos-Fet
• " Check Control" status indicator
  • R emote-controlled start and stop
  • Gold-plated RCA input terminals
  • Professional gold-plated screw-type terminals

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 200 mV 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 30 Hz and 600 Hz.

CONTROLS AND INDICATORS

6 • 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.

7 • 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.
8 • + 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.
9 • 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.
10 • 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.
11 · 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.
