Page 2: Pre-Installation
Pre-Installation This section describes safety conventions used within this document and provides essential information about the Model LVC 5050 amplifier. Review this material before installing or operating the amplifier. AE T is committed to continuous product improvement. ECHRON Technical progress may result in minor variations between this manual and a particular unit. -
Page 3: Safety Conventions
Safety Conventions The LVC 5050 amplifier is a highly sophisticated instrument. Special hazard alert instructions appear throughout this guide. Note the following examples: NOTE: A Note represents information, which needs special emphasis but does not represent a hazard. Page 3... -
Page 4: General Descriptions
General Description The AE T Model LVC 5050 is a dual channel power supply ECHRON amplifier designed for use in high power systems. It can deliver up to 2,500 watts per channel into 2-ohm loads or 5,000 watts bridged into a single 4-ohm load. -
Page 5: Specifications
Specifications Specifications are for units in Dual Mode driving both channels into 8- ohm loads, (26 dB = 20 times voltage gain) and operating from 120 VAC, unless otherwise specified. “Standard 1 kHz Power" refers to maximum average power in watts at 1 kHz with 0.1% THD. - Page 6 Controls Front Panel: A push “On/Off” power switch; also, a signal level control for each channel. The level controls are wired to the PIP card and may be enabled or disabled. Back Panel: A 3-position switch selects Dual, Bridge-Mono, or Parallel- Mono mode. A 3-position switch selects 20, 70, or 140 voltage gain for each channel.
- Page 7 Connectors Inputs: Euro-style screw terminals will accept up to 16 gauge bare wire. Outputs: Unique output bus with dual banana jacks on 3/4 inch centers, and high current ring or spade lug barrier connectors. AC Line: “TT" style, 3 wire, 30A grounded connector (for 120 VAC units).

Page 8: Front Panel Functions
Front Panel Functions The following illustration, with captioned call-outs, provides a visual location of the LVC 5050 front panel functions. A. Dust Filters The dust filters remove large particles from the air drawn in by the cooling fans. Check the filters regularly to prevent clogging. The filter elements can be easily removed for cleaning by gently pulling them away from the front panel. -
Page 9: Back Panel Functions
Back Panel The following illustration, with captioned call-outs, provides a visual location of the LVC 5050 back panel functions. G. Power Cord Units set up for 100 to 120 VAC have a 10 AWG, 30 amp line cord, while units set up for 200 to 240 VAC have a 12 AWG, 20 amp line cord. - Page 10 H. Output Connectors This high-current output block is provided for output connection. Its connectors accept banana plugs, spade lugs or bare wire. There is a detachable output cover (not shown) used to protect against accidental short circuits and dangerous electrical shock. I.

Page 14: Installation
5050 amplifier with special emphasis on system installations. Unpacking Every AE T Model LVC 5050 is carefully inspected and ECHRON tested prior to leaving the factory. Carefully unpack and inspect the unit for damage in shipment. Besides the amplifier, you should find this manual and mounting hardware in the package. -
Page 15: Mounting
Mounting The LVC 5050 is designed for standard 19-inch (48.3 cm) rack mounting and "stack" mounting without a cabinet. For optimum cooling and rack support, multiple units should be stacked directly on top of each other. To reduce the risk of ELECTRIC SHOCK or FIRE HAZARD, DO NOT expose the LVC5050 to rain or moisture. -
Page 16: Cooling
Cooling NEVER block the air vents in the front or back of the amplifier. These amplifiers DO NOT need to be mounted with space between them. If you must leave open spaces in a rack for any reason, close them with blank panels or poor airflow will result. -
Page 17: Making Connections
Making Connections Before beginning the installation of your amplifier, check the following: Remove all power from the unit. Do not have the AC cord plugged in. Turn input level control down (fully counter clockwise). The input and output jacks are located on the back panel. Use care in making connections, selecting signal sources, and matching loads. - Page 18 8. Never connect the output to a power supply output, battery, or power main. These connections will cause serious damage to the amplifier. 9. Do not permit unqualified personnel to tamper with circuitry. Do not make unauthorized circuit modifications. Serious damage to the amplifier and/or safety hazards may result.

Page 19: Dual Channel Hookup
Dual Channel Hookup In Dual Mode, installation is very intuitive: input Channel 1 feeds output Channel 1, and input Channel 2 feeds output Channel 2. To activate Dual mode: Turn off the amplifier Wait 10 seconds for the power supply to discharge Slide the Dual/Mono switch to the center position Connect the output wiring as shown below. -
Page 20: Bridge-Mono Hookup
Bridge-Mono Hookup Bridge-Mono mode is intended for driving loads with a total impedance of 4 ohms or more (see Section 2.4.3 if the load is less than 4 ohms). Installing the amplifier in Bridge-Mono mode is very different from the other modes and requires special attention. To activate Bridge-Mono mode: Turn the amplifier off Wait at least 10 seconds... -
Page 21: Parallel-Mono Hookup
Parallel-Mono Hookup Parallel-Mono mode is intended for driving loads with a total impedance of less than 4 ohms (see Section 2.4.2 if the load is 4 ohms or greater). Installing the amplifier in Parallel-Mono mode is very different from the other modes and requires special attention. To activate Parallel-Mono mode: Turn off the amplifier Wait at least 10 seconds... -
Page 22: Connecting Power
Connecting Power The LVC 5050 uses a 3-wire (grounded) AC line system. At times, the third wire ground may introduce a ground loop into the system. Each LVC 5050 is supplied from the factory with an appropriate AC cord. ... - Page 23 Notes Page 23...
