SAFETY PRECAUTIONS CAUTION CAUTION WARNING WARNING CAUTION: TO PREVENT ELECTRIC SHOCK, DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS INSIDE, REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. THIS SYMBOL IS TO ALERT YOU OF THE PRESENCE OF UNINSULATED DANGER- OUS VOLTAGE WITHIN THE UNIT'S ENCLOSURE THAT MAY BE OF SUFFI- CIENT MAGNITUDE TO CONSTITUTE A RISK OF ELECTRIC SHOCK. -
Page 3: Introduction
This amplifier is a precision device, designed in an effort to provide the listener with unmatched sound quality, design, and construction. In order to operate your amplifier properly and to realize all of the capabilites of the AMPLIFIER v12, we recommend that you read this entire manual carefully. -
Page 4: Installation Connections
These brief steps will allow you to begin operating your system. Make sure during installation that the main AC power switch on the back of the AMPLIFIER v12 is turned off. While the diagram may be self explanatory, we strongly recommend that you read the detailed instructions following this introductory section. -

5. The FUSE AND VOLTAGE SELECTOR houses a 5 X 20 slow blow fuse and voltage selector cartridge. Should the fuse blow, contact a Coda dealer or call Coda directly. When changing the fuse, or altering the voltage selection be sure this unit is disconected from its AC power source. - Page 6 4. This two color LED indicates that the main power is on. When it is green the balanced inputs are in use. When it is yellow the unbalanced inputs are in use. Note: If a power interruption occurs to the system the AMPLIFIER v12 defaults to bias off.
- Page 7 1. The [POWER] button turns on the bias and opens shunting relays that mute the input. 2. The [ > ] button switches between the balanced and unbalanced inputs. Note: If a power interruption occurs to the system the AMPLIFIER V12 defaults to bias off.
- Page 8 SERIAL NUMBER The bridging switch commons the inputs of the AMPLIFIER v12, were pin 2 of the left XLR commons with pin 3 of the right XLR, and pin 2 of the right XLR commons with pin 3 of the left XLR.

Page 10: Design Philosophy
This allows direct coupling without servo circuitry. The unit also uses output followers operating without feedback. The front end of the Amplifier v12 is designed to operate without ever entering Class B operation as is common in many other designs. This combined with excellent high frequency design insures linear operation at high speed, and translates into a sonic reproduction which is extremely transparent in character. - Page 11 Advanced tracking techniques results in absolute control of bias curents under all conditions in the Amplifier v12. The main power supply of the amplifier consists of a 1600VA toroidal power transformer with dual rectifiers to isolate one set of channels from the other.
- Page 12 The XLR input and output connectors are manufactured by Neutrik of Switzerland. Speaker connecters are also gold plated. 7. Wire - All signal wire has been eliminated whenever possible. Where wire is used, Coda employs solid silver and silver plated copper, 141 strand, 18 guage wire with a silicone insulation.

Also available configured for 120W x 4 channels with 25W Class A. When purchased in this higher power configuration, the amplifier channels cannot be bridged. Any Amplifier V12 can be modified by the factory to operate at the 60W per channel (bridgeable) or 120W per channel (non-bridgeable). Contact the factory for specific details or to discuss the proper configuration for your V12. -
Page 14: Care And Handling
CARE AND HANDLING The interior of the amplifier requires no special care. If exterior cleaning beyond simple dusting is required, any dilute ammonia-based product is recommended. Do not use any abrasive rags, cleaners or chemical solvents on the amplifier. When handling the amplifier, take care not to mar the faceplate. Aluminum is a medium hardness metal and can be scratched by harder tool steels, and the surface can be easily marred if the amplifier is set face-down on a hard surface. -
