2 INTRODUCTION Congratulations and thank you for your purchase of this precision Parasound audio component. The Parasound Model 5250 v.2 is the latest generation of popular and proven audio power amplifiers dating back to 1981. It has been designed for a wide variety of applications, establishing a new standard for audio performance, user-friendliness and utility in custom installations. The versatility of the Model 5250 v.
ac voltage, installation and rack mounting 115v – 230v AC Voltage 110–120V is the typical AC voltage in North America; most other countries supply 220–240V. The 5250 v.2 is internally wired for either 115V or 230V, according to where you purchased it and the voltage that is marked on its carton. If you plug a unit that is wired for 115V into a 230V outlet it can damage it. Note: Only a qualified repair technician should make AC voltage conversions.
4 Rear Panel Connections and Controls Connection Precautions Disconnect the AC cord before making or changing any input, trigger, or speaker wire connections. Make sure there is no strain or tension on any wires that could cause them to pull loose Audio In Jacks Connect the cables from your preamplifier or multi-room controller’s output jacks to the Model 5250 v.2’s channel 1–5 audio Input jacks. We suggest using channels 1 and 2 for your left front (L) and right front (R) channels.
Rear Panel Connections and Controls continued Gain Control Knobs for Channels 1–5 The Gain control knobs should be left at the 12 o’clock Normal setting for most applications. When a Gain control knob is set to Normal the gain for that channel is 29. This is the THX Ultra2 Reference level where 1V input = 28.28V output. 28.28V driving an 8 speaker = 100 watts.
