The Destiny Power amplifier is designed to
produce world beating audio performance, through its continued use of custom
discrete analogue MOS-FET circuitry, which was
first developed for Creek’s amplification products in 1993. This circuitry has
continued to be used with great success since that time and has evolved to meet
the increasing demands for higher power, lower distortion and noise.
The Destiny Power Amplifier uses separate power supplies and voltage referencing
circuitry for each channel. Dedicated windings on mains transformer help it to
achieve >100 Watts into 8 Ohm operation and nearly double that into 4 Ohms.
The Destiny Power Amp uses the same protection circuitry as the Destiny
Integrated amplifier under fault conditions. Protection of the amplifier and
ancillary products under fault conditions is facilitated by an array of sensors
and measurement circuits feeding-back information to its microcontroller that
monitors the amplifier constantly for over-temperature, over-current, DC
offsets, power supply status and over-drive situations. If any of these
conditions is exceeded the microcontroller will take the appropriate corrective
action. This can include, muting the input signal, separating the speaker
outputs and in extreme cases, switching off the mains supply to the power
amplifier circuitry. A log of fault conditions is stored in an internal memory
device, which is also used to remember the last setting used prior to switching
off the mains supply.
The Destiny Power amp is unusual in that it has two separate inputs. Firstly it
has a non-inverting, input via high quality solid metal, gold plated RCA sockets
that connect to the power amplifier directly. It also has active balanced
inputs, via XLR sockets and uses relays to switch between the two inputs. The
Destiny Power Amplifier can select either input from a button on the rear panel
or using the forthcoming Destiny CAN Link system that extends the controls to
another room or proprietary RS232 room controller.
Loudspeaker connection can be from bare wire or audio type instrument plugs,
through high-grade touch-proof screw terminals on the rear panel that can be
switched from the front panel, remote handset or Can Link by gold contact
high-current relays.
Like the rest of the Destiny range of products, the Power Amplifier can switch
into low-current standby operation from the front panel or remote control
handset. Waking up the amplifier can now be performed simply via the Creek
System Remote handset. For the ecologically aware consumer, the Destiny power
amp draws less than 1 Watt of mains current in standby mode.
The metal case of the Destiny amplifier has been constructed from custom
designed extrusions using solid 10mm thick front panel and 4mm thick extruded
side and rear panels that combined with the 3mm thick top and bottom plate to
make a very substantial heavy weight product. In addition the buttons and feet
are machined by computer aided manufacturing techniques, to achieve a very high
quality finish. To isolate mechanical vibration and improve sonic resolution
custom designed 4mm thick Sorbothane ‘TM’ moulded washers are stuck to the
machined disc feet.
All in all, this is the best Power Amplifier Creek have so far made and will definitely compliment the Integrated amp to achieve greater levels of current deliver for difficult loudspeakers that demand high current. They are ideally suited to drive the Epos range of Loudspeakers.
