  • Page 5: Introduction

    1.0 INTRODUCTION The ARES-C is a 16 bit solid state audio recorder / player using PCMCIA cards as its storage medium. The information is stored using the MPEG layer II, G722, µ-law, A-law compression standards and can be optionally equipped with an on-board ISDN circuit allowing direct connection to the ISDN network. Also...

    2.1.2 RS 422 CONNECTOR This is a standard 9-pin RS 422 symmetrical serial communication port for connection to the external world. This connector is for the moment only be used by the manufactory production for test purposes. NOTE: A "lap-top" style PC is not always fitted with an RS 422 port. A converter RS 232 / RS 422 must in this case be fitted to the cable to allow the communication.

    When the cloud position is selected then the display on the editor of the ARES-C will be illuminated for 15 seconds only. If the editor is switched on then it will remain illuminated. This feature allows the operator to have a quick look at the amount of space left in the PCMCIA cards.

  • Page 9: Meter Selection Switch

    2.2.3 METER SELECTION SWITCH The meter selection switch allows the operator to decide which channel, Left, Right or MAX, will be displayed on the meter. The MAX position is for stereo operation of the machine and the meter will indicate the highest level obtained between the two channels and the leds will indicate which channel this corresponds to.

    As long as the switch is held in this position, a sine wave of approximately 500 Hz -6 dB, will be present at the outputs, if the ARES-C is in the test position ( the EE / AUTO / TAPE switch must be in the TAPE position). When the reference switch is held in the upper position during record, the EE / AUTO / TAPE switch may stay in the AUTO position.

  • Page 12: Shift Key (Front Panel)

    The shift key must be pressed (and kept pressed) in order to move through the menus on the LCD display on the front panel of the ARES-C. When it is pressed the five grey transport keys operate using their shifted ARROW features. As soon as the SHIFT key is released then it will act as an ESC and the display will return to the main display screen chosen.

    This is where the removable PCMCIA cards are installed. This slot can hold two cards, the upper position being SLOT A and the lower being SLOT B. The ARES-C will work with cards up to 2 Gbytes which conform to the FLASH type SERIES 2 or SERIES 2+, Strata flash cards up to 192 MB and ATA FLASH cards .

    2.4.8 NUMERICAL KEYS Generally the numerical keys are used for the introduction of user information such as telephone numbers when using the ARES-C with the ISDN option. They may also be used in the directory mode to move the cursor directly to a given take number. All take numbers must be entered in 3 digits (ie take 3 must be entered as 003).

    6.0 DIRECTORY RECORDING The ARES-C records a "DIRECTORY" automatically when the card is initially formatted. As recordings are made or edited the directory is automatically updated and is stored in the card. A directory of a card can contain up to 408 "takes" maximum. If the user tries to switch the machine to record and there are already 408 takes on the card then the red LED will not light and the recording will not take place.

    1.0 MAINTENANCE 1.1 Cleaning of the ARES-C As the ARES-C has no moving parts there is virtually no maintenance required. There are no mechanical alignments to be verified. Our only recommendation is periodic cleaning of the exterior of the machine. For this purpose we suggest a soft cloth and Isopropylic alcohol.

    2.3 PLAYBACK 2.3.1 No playback at all (green leds OFF) Check that the internal editor is OFF. (The ARES-C will not playback using the main function selector if the editor is turned ON) Check that the PCMCIA card(s) have at least one take on them that can be played back.

  • Page 95: Microphones

    1.0 MICROPHONES The ARES-C is fitted with internal switchable microphone pre-amplifiers. The microphone inputs are on XLR female connectors on the left-hand side of the recorder. Located above the input connectors are two four position switches (with a slotted head) which allow the powering selection for the different possible microphone types.

  • Page 96: High Sound Levels

    1.4 Use at High Sound Levels Ribbon microphones and bidirectional condenser microphones can be damaged by a large air displacement. To record an explosion, a moving coil microphone, or better still, an omnidirectional condenser microphone is recommended. A switchable microphone (uni-, bi- or omnidirectional) risks the same damage as an ordinary bidirectional microphone.

  • Page 97: Secondary Characteristics

    1.7 Secondary Characteristics Related to Directional Characteristics Omnidirectional microphones (pressure) are much less affected by the wind than bidirectional (velocity) or cardioid microphones (because of their velocity element). The light diaphragms of velocity microphones have a tendency to float in the wind. It has been shown that the velocity microphones are easily damaged by a sudden air displacement (explosion).

    ARES-C it is the signal peak which saturates the A/D converter. The average value of the signal (as far as the listener is concerned) is of no importance to the A/D converter.

    0 dB can be displayed on the input, the A/D will be saturated above 0 dB. The meter of the ARES-C can be selected to monitor either the input signal or the output signal and it is important to be sure that it is indicating the input during recording so that saturation of the A/D converter can be avoided.

  • Page 100: Input Sensitivity

    At 1 kHz, these decibels are the same as phons but as the ARES-C does not have such filters, it cannot be considered as a phon meter.With the sensitivity potentiometer adjusted for 70 dB, a sound of 70 dB captured by a normal microphone (0.2 mV/µbar into 200 Ω) and attacking a normal sensitivity preamplifier, produces a...
  • Page 101 The linear part B corresponds to the zone where the ALC is operating. It will be observed that an input signal variation of 35 dB is converted to an output signal variation of only 3 dB. The linear part A shows that for an input signal variation of 20 dB we also obtain a 20 dB variation at the output, from which can be deduced that the amplifier gain is constant in this zone.
  • Page 102 a noisy place and without interrupting the discussion both parties move to quieter surroundings. Thus, memory time must be limited by discharging the condenser and this is carried out by silence detector S which is activated when the absence of Vout signal lasts more than 2 seconds. Following a sudden -20 dB decrease of the useful signal, the recuperation curve would be as follows: The simple condenser memory described will, however, function quite differently depending on whether load constant is great or small.
  • Page 103 A very short signal at IN input quickly charges C2 and the output voltage immediately acts upon the variable gain amplifier. The same signal, integrated by R 1 Cl has no effect on Cl, but C2 will rapidly discharge through R2 into Cl. Since Cl = 10 x C2, the voltage at its terminals will be hardly affected. The whole operation takes a matter of milliseconds, but both the recording amplifier and the A/D have been protected against saturation.
  • Page 104 Each display icon on the front display of the machine corresponds to a threshold of 6 dB. The operating threshold of the ALC of the ARES-C can be set to one of four different levels. In the -18 dB position 3 icon squares will be alight permanently, in the -24 dB position 2 squares will be alight, in the -30 dB position 1 square will be alight and in the -36 dB position no squares will be alight.

    Hence the central exchange becomes transparent and the ISDN signal passes directly through it. In this case any of the compression modes of the ARES-C can be used as long as both machines are set to the same one before the transmission is made.
