Note: The C500 RECORD OUTPUTS are not affected by the VOLUME or BALANCE Controls. To listen to a different program source while recording, turn the LISTEN Control to the desired source. The recording process will not be affected and will continue.

Output Meters

The C500’s Output Meters indicate the Output Voltage available at the MAIN and SPKR OUTPUT 1 & 2 Jacks to drive Power Amplifiers. Refer to figure 70. The Meters are calibrated in dB

(decibels) and re- spond to all the

peaks contained in the musical infor- mation. They indi-

cate to an accuracy of at least 95% of a

single cycle from a 2000Hz tone burst.

The Meter Electronic Circuitry “Time Stretches” the Meter Drive Signal so the Meter Pointer pauses just long enough for the human eye to see it and is followed by a moderate decay rate.

The following C500 Operating Functions are performed us- ing the supplied Remote Control.

Mono Mode

Press the MODE Push-button once to activate the Front Panel Alphanumeric Display indicating the current mode setting. Pressing the MODE Push-button a second time while the display is indicating the “MONO (On or Off)” will change to the opposite Mode. With the MONO Mode On, the left and right stereo signals will be combined to a mono signal at all Outputs except the Record Outputs. Re- fer to figures 71 and 72.

Note: The C500 automatically stores into memory for each Listen Input, the Selection of the Mono Mode On or Off. After a Listen Input has been Selected, the Front

Panel Alphanumeric Display will indicate the words “MONO ON” for those Inputs where MONO was previously selected.

The 2nd Push-button and OUTPUT1 (SPKR1) or OUT- PUT2 (SPKR2) Push-buttons on the Remote Control allow the sending of the audio signals to separate power amplifi- ers connected to the Rear Panel Balanced MAIN/SPKR1 and Unbalanced SPKR1 or MAIN/SPKR2 and Unbalanced SPKR2. It also activates the TRIGGER Jacks SPKR1 & SPKR2 Jacks on the Rear panel of the C500C. Press the desired Push-button (2nd Push-button followed by pressing the OUTPUT1 [SPKR1] or OUTPUT2 [SPKR2]) once to activate the Front Panel Alphanumeric Display indicating the current Speaker Setting.

Any changes made using the Remote Control Trim Push-buttons will change the previous adjustments made in SETUP. By repeated pressing the TRIM Push-button on the Remote Control, the Front Panel Alphanumeric Display will step through the possible adjustments. These include Input Trim Volume Level, Balance Level Adjustments, Stereo or Mono Mode, Speaker 1 On/Off, Speaker 2 On/Off, Display Brightness (1-7)1, Meter Illumination On/Off1, the Moving Magnet Phono Input Capacitance1 and Moving Coil Phono Input Resistance1. Once the desired Trim function is se- lected use the LEVEL UpS or DownT Push-button to make the change. Refer to the chart on the next page:
