Take Your Creek Amp to the Next Level
The Creek Sequel Plug-In Phono Cards are designed to match a
wide range of MM and MC cartridges and can be fitted to the latest Creek
integrated amps, like the Evo 2, Evolution 5350 and Destiny
The module must be fitted inside the amp, in a slot that will change the
Auxiliary Line input into a Phono input, so either the supplying
dealer, or the user, must physically install the Phono pre-amp before it can be used. The circuitry cannot be switched for MM or MC so the correct module must
be chosen to match the cartridge fitted on the turntable. The Evolution
amp's display will automatically show "Disc" when the amp is fitted with
the Plug-in module and selected for that input.
The Sequel 40 MM Phono pre-amp is the standard device which is
suitable for most medium output Moving Magnet Phono cartridges rated 3-5mV. It is a
two stage circuit and uses high-grade, NE5532 low-noise, integrated
circuits to amplify the signal.
The Sequel 48 MM Phono pre-amp is the special device which is suitable
for low output Moving Magnet Phono cartridges or high output Moving Coil types, rated 2-3mV.
It is a two stage circuit and uses high-grade, Analog Device OP275
low-noise, integrated circuits to amplify the signal.
The Sequel 54 MC Phono pre-amp is the standard device which is suitable
for most medium output Moving Coil Phono cartridges rated 0.5-0.9mV. It is a two stage
circuit and uses high-grade, Analog Devices OP275 low-noise, integrated
circuits to amplify the signal. Due to the very large size of transformer inside the Evolution
5350 and the magnetic field it generates, it is not advised to use the
Sequel 54 with the Evolution 5350, as a higher level of low frequency noise will be heard.
The 75us RIAA de-emphasis is performed
passively following the first gain stage and is directly coupled without
capacitors to block DC, for a clearer sound. A separate DC servo circuit blocks DC and rolls-off low frequencies
below 1 Hz. There is no rumble filter in this design. A second gain
stage boosts the level up to 40dB and uses active feedback for 318 and
3180us de-emphasis using high-grade close tolerance components. The entire circuit is powered from a dedicated supply from the
integrated amplifier, but uses high grade LM317 and LM337 adjustable
voltage regulators set for +/-15V operation. This filters noise from
the main amplifier and allows the Phono pre-amp to have the highest
possible overload margin.
The Sequel Phono cards can be used to enable vinyl input on current and older Creek amplifiers including the following:
- Destiny 2 integrated amp
- Evolution 2 integrated amp
- Evolution 5350 integrated amp
- Classic 5350SE Integrated amp
- 5350SE, 5350R and 5350 Integrated amps
- 5250,5250R and 5250SE integrated amps
- 4330 and 4330SE Integrated amps, but not mk2 versions.
- 4240 and 4240SE Integrated amps
- P42 Pre-amp
