Initial Inspection Inspect the shipping container for damage. If the shipping container or packing material is damaged, it should be kept until the contents of the container have been checked for completeness and the preamplifier has been inspected both mechanically and electrically. This preamplifier was fully tested and carefully inspected before shipment. It should be free of any exterior defects and in perfect operational order upon receipt. If there is any damage or defect or if the preamplifier does not operate correctly, notify your dealer immediately. If the shipping container is damaged or the packing material shows signs of stress, notify the shipper and Jeff Rowland Design Group. Keep the shipping material for the shippers inspection. In the shipping box you will find: - AC power cord - replacement fuses - infrared remote control transmitter - infrared remote control receiver and interconnect cable - warranty card (This form must be completed and returned to JEFF ROWLAND DESIGN GROUP [or its authorized distributor if outside the U.S.A.] within 14 days of purchase. Not only will your preamplifier be registered, but you will, in the future, be notified of possible design updates, improvements and new products.) We strongly suggest that you save all packing materials Features - Six line inputs, the first of which can be used as an optional phono input - Balanced outputs, in both RCA and XLR connector configurations - Regulated power supply with toroidal transformer - Microprocessor-controlled volume and switching - A digitally-controlled resistor matrix volume control provides 200 precise, individual steps - User-stored level settings for all six inputs allow immediate recall of a "normal" level for each source - Dual-rate attenuator adjustment controls provide efficient volume control adjustments - Fluorescent front panel display indicates operational status of the preamplifier under all ambient lighting conditions

- User controlled display shut-off - Infrared remote control of all preamplifier operational functions - Separate remote receiver permits remote operation of preamplifier from a distant location - Image shift control (instead of channel balance trim) maintains overall volume level while shifting stereo image left or right - Mono and left or right channel cut functions - Main outputs are muted temporarily during initial A/C power up, power drop or power interruption - All signal amplification utilizes high-current, Class A, solid-state technology - All inputs and outputs are direct-coupled, thus eliminating the effects of capacitors in the signal path. - Independent power supply regulators are located at each stage of each amplifier channel - Mil-spec circuit board material, with oxygen-free copper traces and high- temperature mask, provides superior electrical characteristics and long term protection against adverse climatic conditions - All signal switching is accomplished with hermetically sealed, gold-clad silver contact signal relays - All critical circuitry is encapsulated in a thermally-conductive epoxy to ensure excellent thermal stability, mechanical integrity and ease of service - Ability to drive any length of interconnect cable into a balanced 600 ohm load - Adjustable input and output impedance minimizes source, load and cable interactions in any application
