Your Gryphon unit has been thoroughly tested and burned-in before shipping; however,
performance will continue to improve during the first 40 – 50 hours of normal use. After this
period, optimum performance will be reached approximately 45 minutes after turn-on.
The main ON/OFF switches on the Commander Preamplifier are located on the bottom panel of
the Power Supply, near the front. In keeping with Commander’s Dual Mono construction, there
are individual power switches for left and right channels. Engaging the power switches will
illuminate the ON/STB (Standby) indicator on the Preamplifier.
If the ON/STB (Standby) switch flashes red continuously in STB mode; this indicates wrong /
defective AC mains voltage. Please disconnect the Commander from AC power and contact
your Authorized Gryphon Dealer or Distributor.
