Page 3: Introduction
23,487 feet or less. Your STEELHEAD RC was packed with extreme love and care. Each box includes the fol- lowing components and accessories: a) 1 each, 6 foot IEC 3-conductor mains power cable (that you will probably replace with an expensive audiophile cord anyway.) -
Page 4: Installation Precautions
INSTALLATION PRECAUTIONS 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. Keep the preamp housing away from sources of strong magnetic fi eld radiation, such as large video display CRTs, large power lines or power/audio transformers in nearby equipment. -
Page 5: Features And Applications
FEATURES AND APPLICATIONS 1. HIGH PERFORMANCE FRONT END The STEELHEAD RC preamplifi er makes the best use of active and passive component and circuit developments generated over the past half-century. The hybrid cascode gain blocks simultaneously deliver wide-band high-gain, low noise and low distortion performance without having to resort to heavy-handed amounts of negative feedback. - Page 6 STEELHEAD, the autoformer has the necessary performance for the job. This pivotal component has had engineering attention lavished upon it in the only way possible or practical: The Manley Labs magnetics department. In-house transformer prototyping and manufacturing capabilities permit realization of extraor- dinary transformer designs.
- Page 7 Each cartridge manufacturer’s product will work best in a laboratory sense when terminated (loaded) with a certain amount of resistance and capacitance. By lab sense it is meant that the signal developed by the cartridge is at maximum power transfer into the pre-amp, with minimum overshoot and ringing, fl...
- Page 8 LINE level sources, you can run the output of another preamplifi er or passive switching device(such as a Manley SKIPJACK) into the Steelhead’s LINE input. It’s novel. Try it. In addition, when the LINE function is invoked, the phono stage remains active, and any cartridge signals present will appear in amplifi...

INPUT and GAIN blue LED’s will illuminate, the MUTE switch lamp will start fl ash- ing and the power supply pilot LED and the MANLEY STEELHEAD RC badge will light up. The winking MUTE lamp indicates the beginning of a 30 second warm-up mute delay,... - Page 10 DURING OPERATION Once audio is heard from the STEELHEAD the exploration for the ideal control settings can begin. However it would be best to allow about 15 minutes of warm-up time for the system to reach thermal equilibrium. Again, notice that the MUTE function operates over both FIXED and VARIable outputs, while the DIM and SUM functions are only available at the VARIable output jacks.

Page 12: Remora Remote Control Operating Instructions
Yes, we installed a new 9V battery in the Remora Remote when it left the factory. Turn on the Steelhead RC and after a few seconds, push and hold either the up or down command buttons. The command is sent via radio signal to the preamplifi er and the motorized volume control will react by mov- ing as directed by the remote switch activation, with motor action occurring as long as a button is engaged. - Page 13 Remora Remote Features! 1. Remote transmitter and receiver operate under crystal-clocked microprocessor control for maximum signal discrimination, fl exibility, and system range. 2. The user may easily reprogram the user-number portion of the remote system’s serial I.D. data stream. This will eliminate the possibility of undesired operation due to remote command collisions.
- Page 14 Having unique handshake ID codes is important for RF remotes since unlike infrared systems, the remote’s RF commands can penetrate walls, fl oors, and doors, which might operate other Manley Remora-enabled gear if they all had the same user- numbers! The user-numbers are a pair of single-digit numbers created by hitting the up and down buttons during a remote transmitter programming session.

Please direct any comments or questions to your dealer or to Manley Labs for further assistance. ** FCC STATEMENT ** This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules.

Page 16: Troubleshooting
TROUBLESHOOTING The STEELHEAD’s system architecture is designed with a variety of features so as to allow fl ex- ibility 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. If trouble is encountered please review the following short list of symptoms and corrective remedies before contacting your dealer or us. - Page 17 Symptom Possible Cause Corrective Action, con’t Lights ON, no output from ei- Open 6922 fi lament, either chan- Check for glowing 6922 fi la- ther channel after warm-up delay nel. 6922 unplugged. ments.

MAINS CONNECTIONS Your STEELHEAD RC has been factory set to the correct mains voltage for your country. The voltage setting is marked on the serial badge, located on the rear panel. Check that this complies with your local supply. Export units for certain markets have a moulded mains plug tted to comply with local requirements. If your unit does not have a plug ... -
