Page 4: Installation Connections
INSTALLATION CONNECTIONS The first section of the installation instructions for the FET PREAMPLIFIER 01 is a diagram of the basic configuration required to bring the preamplifier into an operating mode. These brief steps will allow you to begin operating your system. Make sure during installation that the level control is turned fully counter clockwise, all other components are off, and AC power connections are interrupted to the preamplifier. -
Page 5: Detailed Installation
DETAILED INSTALLATION I. Set up and Installation WARNING: NEVER OPERATE THIS UNIT WITH THE TOP COVER REMOVED. NEVER MAKE ANY INTERNAL ADJUSTMENTS WHILE THIS UNIT IS CONNECTED TO AN AC POWER SOURCE. 1. If the phono stage has been incorporated in the preamplifier it will be necessary to set the gain as well as the loading for each channel prior to installing the unit. - Page 6 LEFT RIGHT 4. Position the FET PREAMPLIFIER 01 in the space which you have chosen, leaving enough space to connect the ancillary components of your audio system, and the AC power cord for the preamplifier. Although the FET PREAMPLIFIER 01 has the ability to reject external fields that produce system noise, it is recommended that the unit not be placed near any sources of strong electromagnetic energy.
- Page 7 DETAILED INSTALLATION II. Source-Output, and Power Connections The input and output connectors are clearly marked on the rear lip of the top cover. It is important to remember the correct left or right channel orientation. The function and channel markings on the rear panel correspond to the front panel controls and their signal paths.
- Page 8 Note: If a power interruption occurs to the system, reduce the OUTPUT LEVEL control gain. The resumption of power will cause no noise pulses in the FET PREAMPLIFIER 01. However, some sources may produce high output voltages on turn on, which may cause damage to an amplifier or speakers .

Page 9: Design Philosophy
DESIGN PHILOSOPHY I. Design Philosophy and Approach The circuitry utilized in your FET PREAMPLIFIER 01 is the result of an advanced and complete design process combining innovation and proven fundamentals. This process avoids both the limitations of total adherence to convention and the flaws resulting from inappropriate application of clever circuit gimmicks. - Page 10 The requirements of a power supply for flawless audio reproduction are straightforward but important. The supplies in the FET PREAMPLIFIER 01 take a very direct approach to high performance. First, a top quality shielded toroid transformer with plenty of reserve current capability is used.
- Page 11 The balanced output connectors are Neutriks from Switzerland. These are black chrome finished with gold contacts. 8. Wire- All signal wire has been eliminated whenever possible. Where wire is used, Coda employs silver plated copper, 141 strand, 18 gauge wire with a silicone insulation.
