ROUTING. Situated at the top of the module are the 24 Track Group routing switches. Each switch sends the output of the module to a pair of Groups, with odd numbered busses being fed from the left panpot output and even numbers from the right. The group busses may also be fed from Aux 1/2 or using ALT TO MTK switch, the Monitor and FX Return channels, the Masters or a pair of patchable inputs.
In the mixing stages however this requirement is reversed, the multitrack feeding the Input Channels and any sequenced sources which are being run "Live" in Sync with the tape feeding the Monitor Channels. On a conventional console, this would mean re-patching all of the sources, but the unique and flexible input facilities of the Ventura 85 make this unnecessary, since the Multitrack ( Line 1 ) and Line 2 sources can be swapped, or even combined, in any configuration simply by operating the appropriate input select switches.
FILTERS & EQUALISATION. Variable high and low pass filters are provided and the IN switch allows easy checking of their effects. The HF and LF sections of the four band EQ are shelving type and are switch selectable to two frequencies each, their gain controls having a range of 15 dB. The MID 1 and MID 2 sections are peak/dip type with continuously variable frequency controls and 15dB of cut or boost. Switches are also provided which allow the " Q " to be selected between broad and narrow settings. The EQ can be switched in or out using the EQ IN button.
INSERTION POINT. The insert send and return appear at the patchbay. The send is unbalanced, while the return is balanced. The insert return is switched in or out of circuit using the INS button. The send is active at all times.
ALT TO MTK. If ALT TO MTK is pressed, the multitrack routing buttons will be disconnected from the channel and will be fed from an alternative source. For channels 1 - 24, this will be the panpot output of the equivalent numbered Monitor Channel. Thus the engineer no longer has to transfer an existing ( and perfectly good ) balance from the Monitors to the Inputs when track bouncing - the existing mix can be sent directly and instantly from the Monitors. For modules 25 - 28 the alternative source is the Balance control output of the stereo FX Return channels ( 25 = FX1, 26 = FX2 etc. ), allowing reverb to be sent to the multitrack without using up two Input channels for each return. The alternate routing source for input modules 29 - 32 is the eight Auxiliary Master outputs (29 = 1 & 2, 30 = 3 & 4 etc. ). This allows the Aux Masters to be submixed with each other, used to generate slave reel guide mixes or, indeed, as an alternative method of track bouncing where appropriate. Finally, modules 33 and above can be provided ( in blocks of four modules, 8 inputs, as an extra cost option ) with balanced patch inputs to their ALT TO MTK switches, allowing any desired source to be sent direct to the multitrack. Two sources which are immediately apparent are external Mic amplifiers ( minimal signal path length ) and the console Group Outputs themselves, which can then be matrixed together.
AUXILIARY SENDS. The 8 Auxiliary Sends from the channel can be configured as eight mono outputs, Six mono sends and One Stereo pair or as Four mono and Two stereo pairs. Auxes 1 - 4 are mono and are each provided with a level control and cut switch. They may be selected PRE - fade in pairs (1 & 2 / 3 & 4) and sends 1 & 2 have an extra button which feeds them to the multitrack routing switches, thus allowing the groups to be used as extra auxiliaries during mixdown. This selection will be overridden by the ALT TO MTK Switch. The remaining sends (5 & 6 / 7 & 8) have the same level controls and Cut and Pre switching, but may be configured as stereo pairs using their ST buttons. When switched, the controls are arranged so that the lower numbered level control of the pair (5 or 7) controls the level of both sends, while the higher numbered control (6 or 8) operates as a balance control. This eases the setting up of stereo headphone mixes and / or stereo effects sends. The PRE and CUT switches continue to function normally in stereo operation.
OUTPUT CONTROLS. The module output may be sent to the Main Mix Buss by pressing the Mix switch and its stereo position set by the Pan control. Two MUTE control groups are provided, allowing combinations of Input and Monitor channels to be muted by pressing the appropriate Auto Mute master switch on the central facilities panel. Channels are assigned to the groups by pressing their Mute 1 or Mute 2 switches and a channel may be assigned to both of the control groups at once. Pressing the SOLO button on a channel will replace the current monitor speaker signal with the output of that module. The signal will retain the stereo positioning and level set by the pan pot and fader, and several modules may be selected simultaneously. N.B. This is not a destructive SOLO Mode, the only thing turned off is the signal currently being sent to the monitor loudspeakers. Pressing the CUT switch will mute the output of the channel including any post fader Auxiliary sends and the SOLO signal.

SELECTION. Input selection on the Monitor channel is controlled by the TAPE and L2 switches. If neither switch is pressed the signal passed to the rest of the channel will be whatever is currently on the same numbered Group Output. If TAPE is pressed this will change to the appropriate Tape Return signal and if the L2 switch is pressed, L2 will be selected as the input. This is the same Line 2 source as is used by the Input channels and this signal can therefore easily be selected to Inputs and / or Monitors. The bargraph follows the input selection.
EQUALISATION. Each Monitor has a 3 band EQ. The HF and LF shelving bands allow 15dB of cut and boost at 10kHz and 100Hz, while the peak / dip mid band gives the same cut / boost with the addition of a frequency pot. The EQ can be activated using the IN switch.
AUXILIARY SENDS. The Monitor channels feature the same 8 Aux sends as the Input Modules. Each send has a level control, Pre fade and CUT switches are provided for each pair of sends (1&2, 3&4, 5&6, 7&8). Pairs 5&6 and 7&8 have the same stereo selection facilities as the Input channels.
OUTPUT CONTROLS. The outputs of the Monitor channels are normally fed to the Main Mix Buss, level and position being set by the Mon and Pan controls. If the ALT TO MTK switch on the corresponding Input channel is pressed, the Monitor output will also be feeding the multitrack routing on that Input Module. This could lead to a situation in which the signal was being fed to the monitor speakers twice (once via the normal stereo buss feed and once via the multitrack). Each Monitor is thus provided with a " BOUNCE " (BNCE) switch which removes that Monitor output from the Main Mix Buss. The procedure for a track bounce would therefore be as follows: If it is desired to mix tracks 3, 4, 5 & 6 onto tracks 1 & 2, press the 1/2 Routing button on the same four Inputs and press the Bounce buttons on Monitors 3, 4, 5 & 6. Turn up the Mon controls on Monitor channels 1 & 2 and pan 1 fully left and 2 fully right. The outputs of Monitors 3, 4, 5 & 6 will now appear on Groups 1 & 2 at the same relative levels and with the same stereo positioning as they had in the Main Mix Buss and their overall levels can be adjusted with Group faders 1 & 2. Their level in the Main Mix Buss (and hence the monitor speakers) is adjusted using the Mon controls in Monitors 1 & 2. If it is necessary to monitor the off tape signal, this can be done as normal by pressing the TAPE buttons on the Monitors 1 & 2. Bear in mind that anything routed to Groups 1 & 2 from other input channels will also appear on tape and in the speakers. Other useful features of the ALT TO MTK switches are that they can be used to subgroup the Monitor channels and to send Monitor L2 sources to the multitrack. An additional use of the BOUNCE button is that it can be used to preserve Monitor post fade Aux sends while NOT sending the Monitor channel to the Main Mix Buss (the Monitor Cut Switch would normally Mute any post fade sends). Below the module are two full length faders which normally control Group Output level. These can be swapped with the Mon level control by pressing the FDR switch in the appropriate Monitor channel. Switches are provided which allow the Monitor channel to be assigned to the two Auto Mute Masters in the Central Facilities Module. Each channel may be assigned to more than one control group and each group may contain Input and Monitor channels. SOLO and CUT function in the same way as for the Input Module.

The Central Facilities Module provides all the master controls and special functions necessary for operation of the console.
OSCILLATOR. The high quality sine wave oscillator provides five selectable frequencies and may be routed to the multitrack and Main Mix busses using the SLATE switch. A level control and ON switch complete the controls. Oscillator output is always sent to the patchbay, where an insertion facility allows an external oscillator or noise source to be sent back to the SLATE switch and thus to the console mix busses.
AUXILIARY MASTERS. Each Auxiliary Master section provides level, SOLO (AFL) and CUT controls for one of the 8 Sends. When SOLO is pressed odd numbered sends will be placed in the left speaker and even numbered sends in the right, allowing easy checking of Stereo mixes created on sends 5/6 and 7/8. The master sends may also be sent to the Multitrack by pressing the ALT TO MTK buttons on Input channels 29 - 32 (29 = sends 1 & 2, 30 = sends 3 & 4 etc.). Auxiliary Sends 1, 3, 5 & 7 will be sent to the odd numbered groups and sends 2, 4, 6 & 8 will be sent to even numbered groups.
FX RETURNS 1 & 2. Four identical stereo FX Return channels are provided. Each Return is sent to the Main Mix Buss and has controls for level, stereo Balance, Solo (AFL) and CUT. A 2 band equaliser identical to that used in our TSM, Series 80 and Ninety consoles provides 15dB of boost or cut at 100Hz and 10KHz. The output of each return may also be sent to Aux send busses 5 & 6 and/or 7 & 8 via the level controls and routing switches provided, allowing simple addition of reverb/FX into headphone mixes. If the ALT TO MTK switches on Input channels 25 - 28 are pressed, the FX Return output may be sent to the console Groups using the routing buttons on the appropriate input module (25 = Return 1, 26 = Return 2 etc.). This signal is taken after the FX Return LEVEL and BALANCE controls but before the CUT Switch, allowing the output to be removed from the Main Mix buss while still being sent to the groups. The left output will be fed to odd numbered groups and the right output to even numbers.
FX RETURNS 3 & 4. The functions of FX Returns 3 & 4 are identical to those provided in Returns 1 & 2.
MONITOR MASTERS. The Ventura 85 allows the use of one main and two ALTernate pairs of monitor loudspeakers. These are selected using the ALT 1 and ALT 2 switches. Level controls for ALT 1 and ALT 2 are arranged as trims of the main MONITOR level control at the bottom of the central facilities panel so that levels do not have to be continually adjusted when switching between pairs of speakers. MONO, DIM (-20dB) and CUT switches are fitted and control whichever pair of loudspeakers is currently selected. If no other selection is made the source signal for the monitors will be the output of the Main Mix Buss. One of four external 2 Track sources may be selected using the buttons provided, or if a SOLO switch is pressed, the Monitor speaker signal will be the output of the Solo Mix Buss, the level of which may be adjusted using the SOLO control. A pair of Studio Playback speakers may be driven from the STUDIO level control and CUT switch. The source for these will be either the Main Mix Buss or one of the external 2 Track sources, whichever is currently set as the (non - Solo) control room monitor source.
TALKBACK. Switches are provided to enable Talkback to SLATE (Group Output busses), STuDio Playback speakers and AUX Masters. A Talkback level control sets the volume of the internal microphone fitted at the top of the central facilities panel.
MISCELLANEOUS. As previously discussed the two AUTO MUTE master switches provide control of the Input and Monitor channel CUT facilities. Pressing either switch will mute the outputs of any channel assigned to it. Two "USER" switches are provided to allow control of cue lights, dimmers, cart machines etc.
AUTOMATION The Ventura 85 can be supplied pre - wired for Optifile VCA automation, or can be fitted with a number of other VCA or Moving Fader systems.
