Page 9: Features
— The XPA U 1004 SB and the XPA U 2002 SB do not have internal fans or • vents for cooling, ensuring quiet reliable operation. The units generate substantially less heat than conventional power amplifiers, making the XPA Ultra Series ideal for rack-mount applications where space is limited. Rack Mounting Ventilation Recommendations on page 7. - Page 10 Ultra low inrush current at power up - no need for power sequencing — Allows • multiple XPA Ultra amplifier to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing. Power factor correction - removes harmonic content on AC line — The XPA U •...

No sound should come out. Raise the attenuation on the XPA Ultra Series amplifier until sound distortion occurs, then lower the attenuation level slowly until distortion disappears. This setting ensures no clipping occurs, whatever the source device volume setting is.

- Page 23 WARNING: AVERTISSEMENT : • Do not tie channel output pins to each other or to ground. Doing so will short out the outputs, damage the amplifier, or both. • Ne pas lier les sorties 1 et 2 des canaux entre elles ou à la terre. Les sorties pourraient être court-circuitées et/ou l’amplificateur pourrait être endommagé.
