DYNAMIC RANGE Button 
DWN Button 
Digital sources are capable of wide dynamic range (the difference between the softest and loudest sounds). In some cases, this may tax amplifiers and/or speakers. In other cases, you may want to reduce the dynamic range when listening at low volume levels. Pressing the front-panel DYNAMIC RANGE button (or the DWN button on the remote) steps through the three dynamic range settings:
•MAX (no compression/full dynamic range)
•MID (moderate compression)
•MIN (full compression/minimum dynamic range)
A “D. RANGE” indicator in the front-panel dis- play lights when the dynamic range is not set to the MAX setting. The new dynamic range setting appears briefly in the alphanumeric display when the setting is changed.
NOTE: The DYNAMIC RANGE feature is only available in Dolby Digital mode. It is designed to keep dialog intelligible while adjusting the loudest and softest sounds.
Tuner Controls
The RSX-1055 features a digital synthesized AM/FM tuner with RDS capability and 30 station presets. The unit offers a wide range of tuning options. Here is an overview of the tuning options (more detailed information is provided in subsequent sections of this manual):
•Manual frequency tuning tunes up or down to the next station frequency (when in frequency tuning mode). Press and re- lease a TUNING button (CH UP/DOWN on the remote) to tune.
•Direct frequency tuning lets you en- ter the desired station frequency digits. Press the DIRECT button (or the +10 button on the remote) and enter the digits using the NUMERIC buttons.
•Automatic frequency search tuning searches up or down to find the next re- ceivable broadcast signal. Press and hold a TUNING button (CH UP/DOWN on the remote) for at least one second to search up or down.
•Station preset tuning lets you directly enter the number of a memorized station preset. Enter the number of the memorized preset using the NUMERIC buttons.
•Preset search tuning jumps up/down to the next memorized station preset. When in PRESET mode, press a TUNING button (CH UP/DOWN on the remote) to select the next station preset. Press the PRESET button on the remote to toggle between preset and frequency tuning modes.
•RDS (Europe) or RBDS (USA) tuning provides a range of special tuning and search features based on data codes en- coded with the broadcast signal. See the RDS section of this manual for detailed information.
NOTE: The RSX-1055 comes configured for tun- ing in the market where you purchased it (N. America or Europe). To change this default set- ting, see the information on the DEFAULT SETUP on-screen menu later in this manual.
BAND Button 
Press the BAND button to toggle between AM and FM reception. An indicator in the front- panel display confirms your choice and the currently tuned station frequency is shown.
TUNING Buttons 
The TUNING buttons (labeled CH UP/DOWN on the remote control) provide three different tuning functions, depending on the mode of operation.
In the normal FREQUENCY tuning
mode, press a TUNING button (CH UP/ DOWN on the remote) and release to manu- ally jump to the next station frequency, regard- less of whether or not a station is broadcast- ing on that frequency. For auto frequency search tuning, press and hold the TUNING button for approximately one second. An AUTO indicator will appear in the front-panel display and the tuner will begin scanning up or down through the frequencies until the next available signal is detected. If this is not the desired station, repeat the automatic tuning procedure to find the next station. Weak stations will be skipped during auto tuning.
In the PRESET tuning mode, press a TUNING button (CH UP/DOWN on the re- mote) and release to jump to the next memo- rized station preset. Switch between FRE- QUENCY and PRESET tuning modes by press- ing the PRESET button 
on the remote con- trol. A PRESET indicator appears in the dis- play when PRESET TUNING is activated.
In the RDS PTY search mode, press a TUNING button (CH UP/DOWN on the re- mote) to select the desired program type from the scrolling list in the display. See the section on RDS tuning for more details.
NOTE: Several indicators in the front-panel dis- play assist tuning. A large display shows the tuned frequency. A TUNED indicator lights when a sufficiently strong signal is received. A ST indicator lights when a stereo FM signal is received.
MEMORY Button 
The MEMORY button is used with the NUMERIC buttons to store memorized station presets. See the next section for detailed instructions.
NUMERIC Buttons:
Station Presets 
The RSX-1055 can store up to 30 station pre- sets for recall at any time using the NUMERIC buttons on the front panel. To memorize a sta- tion:
1.Tune to the desired station, AM or FM.
2.Press the MEMORY button on the front- panel. A MEMORY indicator will flash for five seconds in the front-panel display.
3.While the MEMORY indicator is flashing, press the number of the preset where you wish to store the station frequency. For example, to memorize the station as pre- set 3, press the 3 button. To memorize preset 15, press the 1 button followed by the 5 button.
4.A previously stored frequency is erased from memory when a new frequency is memo- rized for the same preset number.
To tune to a previously memorized station, just press the preset number on the NUMERIC buttons. For example, to tune to preset 3, press the 3 button. To tune to preset 15, press the 1 button and then press the 5 button.
