User manual SIMA SED-CM

[. . . ] Heed Warnings - All warnings on the appliance and in the operating instructions should be adhered to. Follow instructions - Follow all operating and use instructions. Water and Moisture - the appliance should not be used near water - for example: near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool. Ventilation - The appliance should be located so that its location or position does not interfere with proper ventilation. [. . . ] 11 ­ RS-232C Connect to your home automation system or PC. 12 ­ 15V DC Input from the AC wall power supply Note: The rear panel inputs #5 can not be used if input #5 on the front panel are connected. Page 6 IR Remote Control The IR remote control allows you to control all of the functions available from the unit's front panel, with the addition of a DIM setting. POWER ­ Toggles between Active and Standby mode. DIM - Pressing this button cycles through four levels of brightness on the front panel lights-100%, 75%, 50%, 10%. VOLUME STABILIZER ACTIVE - Toggles between the Volume Stabilizer being Active or in the Bypass mode. AUTO SCAN - Toggles between the Auto Input Selection mode being on or off. INPUT SELECT 1 through 5 - Selects desired input. Be sure to install the two AAA batteries in the remote before using. Slide the cover open on the remote in the direction of the arrow and install the batteries as shown inside the unit. Fig. 3 Page 7 Typical Hook up Step 1 Connect the AC adapter to 120 VAC and plug the DC cord into the 15 VDC input on the rear of the VS502. Step 2 You will need to determine how you want to use your system. A new input becoming active will cause the unit to wake from standby, and select the new input. When the unit is in the standby mode, the Power/Standby light will be dim and all other lights will be off. When a video device is turned on, like a VCR on Input #1, the Power/Standby LED will turn off; the input corresponding to the device will turn on, along with the Auto Select LED. If a second device is turned on (say the DVD player on input #2) the # 2 light will illuminate and it will be selected and fed to your TV. If the second device is turned off, after about 5 seconds, input #1 will be selected. If both devices are turned off, after about one minute, the SED-CM will turn off and go into standby mode waiting for an input. Note: If an input goes off and back on in less than 5 seconds, the SED-CM will not sense the input change so no input change may occur, to avoid flicker. Volume Stabilizer Active (Only on analog audio ­ no effect on digital audio) If the Volume Stabilizer Active light is on, then the output of the audio switcher will be routed through the Volume Stabilizer circuitry. When the Volume Stabilizer Active light is off, the audio signal is bypassed and the Volume Stabilization setting will not have any affect on the audio signal. Page 11 Volume Stabilization Adjustment Volume Stabilization lets you control the dynamic range of the audio signal to accommodate your needs. The Volume Stabilizer light must be on for this to function. The numbers show the ratio of the input signal to the output signal in dB. Thus, the setting in the middle (1:1) means that the input signal is the same as the output signal. Likewise, if you set Volume Stabilization to the 10:1 setting, it means that a 10-dB change in the input volume level will result in only a 1-dB change in the output level. This will tend to keep the volume constant even when the sound changes from soft to loud and back to soft. Setting 10:1 Description Maximum compression maintains constant volume level by compressing dynamic range Modest compression Slight compression Normal volume fluctuations Slight expansion Moderate expansion Maximum expansion increases dynamic range Use Watching movies late at night Background music Making tapes for airplane use Making tapes for automotive use Minimal audio compression Just like bypass (VS off) Adds some impact to audio sources Adds moderate impact to audio sources Restores dynamics to old recordings Reduces hiss and noise below noise "floor" Can "un-do" compression on tapes made with 2:1 compression 2:1 1. 3:1 1:1 1:1. 3 1:1. 7 1:2 Hint: If you want the minimal volume changes when changing sources, changing channels or watching a movie, be sure the Volume Stabilization is set to the 10:1 position and the VS ACTIVE light is on. [. . . ] Volume seems to vary too much between sources IR remote does not work Solution Make sure power adapter is plugged into a working outlet. Stand-by light is dim (normal in stand-by mode) Is standby light off?Make sure inputs and outputs are not reversed. Make sure inputs and outputs are not reversed. [. . . ]
