AMBIT TUNER Plug-in FM/AM Tuner Instruction Manual Rev 1.
User Instructions for the EVOLUTION 50A integrated amplifier, when using the AMBIT Tuner. Thank you for purchasing the AMBIT Tuner Module from Creek Audio. You are now in possession of a State of the Art FM/AM analogue Tuner with RDS (Radio Data Service). The AMBIT tuner module is an upgrade option, suitable only for the Evolution 50A and Evolution 100A Integrated Amplifiers.
Insert the Flat Foil Cable (FFC), exiting from the AMBIT module, into the appropriate socket on the Pre-amp PCB below it, marked MODULE. The AMBIT PCB should now be held upside-down (components facing down, bare PCB facing upwards) with the antenna sockets facing backwards towards the rear panel. Fold the loose FFC under the AMBIT PCB. 1. For EVOLUTION 50A version 1: Push the antenna sockets through the appropriate holes on the rear panel.
na to the AM antenna clips on the rear panel, either way around. Press the buttons down to insert the bare wires and release them to grip the wires. Place the loop away from the amp and somewhere that is not going to block the AM signal. Rotate the loop to point at the station transmitter, for best results. This may vary from station to station, as the location of each station will be different.
1. Seek or manually tune to a station; Press and hold PRE button until a Preset location number flashes on the screen in place of FM or AM text. The flashing number indicates the preset location immediately following the last one in use, making it convenient to program a series of presets in a row. If you wish, you can change the offered preset location by turning the control knob. To confirm and store the tuned frequency into the selected preset location, press PRE again briefly.
Signal Strength, Signal-to-Noise Ratio and Multipath distortion. 8. Stereo is displayed in three settings: The Infinity symbol is full width STEREO, two overlapping circles means partial stereo and a single circle means MONO. 9. PS, means Program Service, indicating that station name is available. 10. RT, means Radio Text is available. Up to 64 characters of textual information about the station, DJ, music or other information may be transmitted by this method. 11. CT, means Time data is available.
Receiver was previously in Line input mode. MODE switches between PREset mode and TUNE mode. MONO manually forces the FM tuner into mono in three stages, for when an FM stereo signal may be too noisy to listen to in Stereo. Normally, the AMBIT Tuner will automatically adjust the amount of stereo separation, from full stereo to mono, to maintain a good signal to noise. Other Buttons DIM changes between three levels of display brightness. Display off is not possible. NUMBERIC buttons 0-9 1.
