TM401

Mono Input/Group Module


The mono input and group module TM401 is the basic input module of the ToolMod analog mixing console. The rich feature set together with an attractive price make possible to configure a versatile analog line mixing console with 16 channels at a total price below € 8500.

TM401 Features in Brief

  • 3 balanced inputs for external mic-pre, line level source and DAW output
  • 2 balanced and buffered, switched insert points
  • 6 mono auxiliaries and 1 stereo cue send
  • Group bus amp that can be connected to one of the 16 group busses of the ToolMod console frame by jumpers on the module pcb.
  • The group bus amp can be switched to the input section and makes possible to use the module as sub group master alternatively.
  • The output section allows routing into the 16 groups and the main stereo master. The group routing can be driven from the pan pot output or from a separate level and pan control alternatively. Using these controls lets allows using the routing system for additional mono or stereo auxiliariess as well.
  • Using the MON switch in the routing section feeds the routing matrix from the DAW when the module is used as group master.
  • PFL, Solo in Place, and a 3-color peak-present level indicator are included as well as access to the two mute groups.

Input Section
The default input is the 'Tape' input that is normally used for the output of a DAW. MIC and LINE select the corresponding inputs for external pre-amps alternatively. All inputs are electronically balanced and can handle input levels of more than + 30 dBu.

The GRP switch selects the output of the internal group bus amp, which makes it possible to use the module as group master alternatively. GRP overrides any other input selection.

The input gain control with +/- 20 dB range and calibrated center detent is active with the selected input.

Insert Section
The TM401 mono input module has two independent insert points. Both inserts, INS A and INS B are buffered and electronically balanced. Like all other inputs and outputs, the inserts can handle levels of more than + 30 dBu. Each insert has its own On-switch.

The REV switch reverses the order of the two inserts. Pressing REV moves INS-B pre INS-A.

Due to the two independent insert points, it is possible to install two processing devices, e. g. equalizer and compressor and reverse the order of both without that patching or reconfiguration is necessary.

Auxiliaries
The TM401 input module has 6 mono aux sends and a stereo cue send. The 6 mono sends default to post fader. Each send has a PRE switch that moves the send pre fader. An internal jumper determines if the aux sends are muted by the solo in place system when switched pre fader.

The stereo Cue send has independent level and pan controls. In the default position, Cue is pre fader, pre solo. The POST switch puts the Cue section post fader. The CUT switch mutes the entire Cue Section. If the Cue send is used for playback mixes in pre fader mode, the CUT switch is a useful feature, since it makes possible to mute playback signals independent of the state of the main channel.

Fader
The external fader module can be the mono version of the standard audio fader TM451 or the mono vca fader with automation interface TM455. Even without automation system installed, the four vca groups can be used, if one of the vca group master modules TM461 or TM462 are installed. The CUT switch is included with the fader module.

PFL, Solo, Peak-Led, Mute-Groups
PFL and Solo in Place are independent systems that are both available with the TM401 input module. PFL only affects the control room section. Solo in place mutes all input channels that are neither switched LOC(al) - which is equivalent to 'safe from Solo' - nor in Solo Mode. Solo mutes the entire channel, which makes it possible to listen to the channel(s) in solo with the original level and pan and, if required, with reverb and echo and any other effect that is driven from an aux send. The Peak-Present level indicator reads the fader input signal. The 3-color led lights up green when the level is above - 20 dB and turns to yellow at 0 dB. With higher levels, the color changes from yellow to orange and red. With red color, the remaining headroom is 5 dB. The two mute groups CUT GR A and CUT GR B can be selected independently with two push buttons. The mute group master switches are installed in the master module TM411. Cut from a mute group works not different from a local Cut.

Metering
The metering can be installed in additional frames that can be mounted on top of the mixing frame or in a rack. Each channel has two meter sends that can be configured by jumper blocks on the module pcb. The meter send 1 can be set to the calibrated DAW return input, the selected input pre input gain, pre main fader or pre record fader, which is equivalent to the signal that drives the group routing. Meter send 2 reads the channel output, the fader output, or the group output. It is up to you to install single or dual meters or to omit the entire meter. High-resolution LED PPM's and VU meters are available. The meter sends are unbalanced and buffered and can drive any external meter with an appropriate level range. The meter outputs are available on a 9-pin D-sub connector per channel.

Pan Pot
The Pan Pot is driven from the fader output. It is implemented as standard mono to stereo pan with 3 dB center attenuation and center detent. The output of the pan pot drives the main stereo bus if the MIX switch is pressed. In addition, the groups 1 to 6 can be switched to the pan pot output by the switch TO RTG 1-8. In this case, the routing section is divided into two blocks of 8 groups.

Routing Matrix
The routing matrix has 8 switches for the 16 mono groups, arranged in stereo pairs. The input is driven from the REC level and pan controls. With no switch pressed, only the odd numbered groups are driven. Pressing EVEN selects the even numbered groups. In both cases, the routing is fed in mono from the output of the REC fader, which has a calibrated center detent at 0 dB. Pressing PAN switches over to stereo drive and inserts the routing pan pot. The input of the REC fader defaults to the main fader output. It can be switched pre fader pre solo by the PRE switch. The MON switch overrides PRE and connects the REC fader to the DAW return input 'Tape'. This feature allows to feed the track output to a group, using the REC fader and the RTG PAN for level and pan control, while the channel is used in group mode. If the routing is used in split mode with TO RTG 1-8 pressed, the group switches 1 to 8 are assigned to the main pan pot while the groups 9 to 16 are still used as described above.

Channel Output
The signal at the channel output depends on the position of the DIR switch. If DIR is not pressed, the output of the internal group bus amp drives this output. With DIR pressed, the channel output is driven from the fader output.

Group Bus Amp
The internal mono group bus amp of the TM401 input module can be assigned to one of the group busses by a jumper block on the module pcb. The bus amp output is available on the channel output if the DIR switch is not pressed. In addition, internal group return rails make possible to access the group bus amp outputs in other modules as well.
