Unpacking
Save your carton and the packing inserts for future safe transport in case you move or your unit ever
requires shipping for repair. Note, the white printed carton is not itself strong enough for safe shipping, so
you absolutely must place it into the additional outer "overcarton" before shipment.
The AC cord is packed separately in the carton. This is a specially selected audiophile grade cord and is the
only cord we recommend for use with your HCA-600. Please don't lose it.
Before you proceed, find the serial number which is located on the rear panel of your unit and record it here
for future reference or in case of casualty loss or theft:__________________________

Page 3: Making Connections
Always place your unit horizontally. Do not place your unit directly on a carpet whose pile could interfere with air flow into its bottom vent openings. If you place your HCA-600 on the floor near your speakers, put its feet on a piece of wood to elevate it above the pile of the carpet. If you stack your components, it's better to place your HCA-600 alongside your other components. -
Page 4: Mono Bridge Switch
You may use 4 Ω rated speakers for mono bridged operation only if you don't intend to run your HCA-600 at high levels for extended periods. We recommend an 8 Ω minimum mono load. - Page 5 In many cases, this will eliminate the problem. If this fails, it may be necessary to reverse the direction of the HCA-600's AC plug. Please do not cut off its 3rd ground pin;...
- Page 6 LEDs illuminate. Level Controls The HCA-600 will sound best with its level controls set to maximum where they are effectively out of the audio signal path. However, if your preamplifier has very high gain, and its volume control cannot track properly for left-right channel balance near its minimum position, it may be necessary to reduce the input level control settings on the HCA-600.
- Page 7 Make sure the unit is turned off while you do this. Fuse The HCA-600 has one external 4 ampere fuse which may blow as a result of an internal fault condition. This protects the unit from possible damage to internal parts. Never replace this fuse with a larger value. Substi- tution of a larger fuse may create serious stress or damage to internal parts and will void your warranty.
