Page 5: Electromagnetic Interference (Emi)
nstallation The ET2 dissipates approximately 20 watts of heat, and must be adequately ventilated. Mount the unit horizontally on a flat, hard surface, and take care that the ventilation holes in the bottom are unobstructed. Allow at least two inches of clearance above the unit and keep the cabinet or shelf open at the back. - Page 6 Physical location and cable “dress” can be an important factor in minimizing hum pickup. The installation should situate the pream- plifier well away from the power amplifier, and power (ac mains) cords should be dressed to remain at least 4" (100mm) away from input/output cables.
- Page 7 onnection SOURCES (TUNER, CD, VIDEO, AUX2): These high level inputs are electrically equivalent. These inputs present a 13.5 kOhm load to the source. Connect the corresponding source components to these inputs. PH/AUX1: If the optional phono stage is installed, this input pro- vides the extra gain and RIAA equalization required for playback of LPs.
- Page 8 ontrols <power>: Press the switch labeled power to switch the preampli- fier on. A time delay auto-muting circuit is incorporated into the ET2 to suppress turn-on/turn-off transients. All outputs are grounded via relays for approximately 45 seconds after the unit is turned on in o rder to suppress warm-up transient noises.

Page 9: Remote Control
Remote Control All operations of the ET2 can be controlled by the wireless remote unit. MUTE: Pressing the mute button will cause the main outputs to mute and the level display to be zero. Pressing it again will restore the last level setting. Pressing and holding the mute button for more than three seconds will switch the ET2 into standby mode (all tube circuitry switched off). - Page 10 Therefore, we highly recommend that you purchase replacement tube sets from conrad-johnson design. We anticipate tube life to accommodate two to three years of operation without degradation in normal use - if the preamplifier is switched off when not in use.
