THANK YOU!... ...for choosing The MANLEY STEELHEAD phono preamplifier . Please read over this manual carefully as it contains information essential to the proper operation and maximum enjoy- ment of this fabulous instrument.
INST ALLA TION PRECAUTIONS a) Avoid locating the preamp where it will be exposed to direct sunlight, excessive humidity, dust or moisture. Extreme environments may temporarily or permanently degrade preamp performance.
FEA TURES AND APPLICA TIONS 1. HIGH PERFORMANCE FRONT END The STEELHEAD preamplifier makes the best use of active and passive component and circuit developments generated over the past half-century.
3. SWITCH-SELECTABLE CARTRIDGE LOAD IMPEDANCE An effective means of varying the load seen by the MC cartridge has been included in the form of a 5-position rotary switch. This switch selects various taps on a specially manufactured dual-primary bi-filar wound, high-bandwidth low-resistance and multiple-shielded nickel-core step-up autoformer.
Each cartridge manufacturer’s product will work best in a laboratory sense when terminated (loaded) with a certain amount of resistance and capacitance.
7. LINE INPUT SELECT BUTTON The LINE switch routes external line level signals to the top of the feature switch stack, and through the VOLUME control. In this way, an external signal source may be manipulated by the SUM, DIM and MUTE switches, along with the volume control, before transmission to any downstream power amplifiers.
OPERA TIONAL NOTES BEFORE POWER-UP Once placed, join the power supply cable to the pre-amplifier via the large16-pin circular connector. The 16-pin connectors are keyed and can only be mated when both halves are lined up correctly. Check and make sure the power supply is switched off, then attach the grounded IEC power cable jack to the IEC plug.
The winking MUTE lamp indicates the beginning of a 30 second warm-up mute delay, during which time the muting relay is engaged; no output will be heard from the preamp. DURING OPERATION Once audio is heard from the STEELHEAD the exploration for the ideal control settings can begin.
Let the preamp tube(s) cool down, if necessary, before handling. Tube heater filaments are somewhat more suceptable to damage when warm or hot. Each tube should require only moderate force for removal and replacement. Gently rock the tube back and forth a bit during removal or replacement.
TROUBLESHOOTING The STEELHEAD’s system architecture is designed with a variety of features so as to allow flexibility in accommodating as many cartridges and as much downstream gear as possible. Access to these capabilities rest on the assumption that all STEELHEAD systems are functioning properly.
