Direct Pro Interface Box - Front

DIRECT PRO 24/96 INTERFACE BOX

The Direct Pro 24/96 interface box houses 4 shielded analog combo jack inputs, 6 shielded analog out- puts, MIDI IN and MIDI OUT jacks, and a headphone jack for monitoring. Additional S/PDIF IN and S/PDIF OUT jacks are on the Direct Pro 24/96 PCI host card.

Front Panel

The Direct Pro 24/96’s front panel consists of 4 analog combo jack inputs, a headphone output, and phantom power controls.

The combo jacks accept either 1/ 4", or XLR mic connectors. The 1/4" inputs can accept either bal- anced (+4dBu) or unbalanced (- 10dBV) signals. The XLR jacks have built-in preamps with 60 dB level trim. In addition, they are

equipped with an invariable 48V phantom power, allowing you to power professional condenser micro- phones.

WARNING: All line level connections MUST use the 1/4” input. XLR inputs are ONLY for microphones. If the inputs are used incorrectly, damage may occur!

Phantom Power

The phantom power on/off switch activates phantom power for all 4 XLR inputs. Phantom power is not delivered to the 1/4" input.

Headphone Jack

The headphone output enables you to monitor the audio without speakers.

Note: The headphone Jack is optimized for 60-150 ohm headphones. Headphones with impedance higher than 150 ohm will sound softer.

Input Volume Faders (cont’d)

STEREO

This button on Channel 1 links all the effects and knobs of that strip with Channel 2, and the same is true with Channel 3 & 4. This can also be thought of as a ‘Link’ button because every control on either strip affects the other strip. There is no ‘master’ or ‘slave’ strip because changes on either strip will directly make changes on the other.

The PAN slider at the bottom is automatically forced in the far Left and far Right positions. The PAN slider is not ‘linked’ to the corresponding strip.

Only Channels 1 & 2 can be linked and Channels 3 & 4 can be linked. There is no way to ‘link’ all 4 input strips together.

•MUTE: Turns off the channel’s signal entirely

•SOLO: The opposite of mute. Soloing an input channel will mute all other output channels. It will be the only sudible channel.

REC FX

This button allows flexibility in recording the effects that are on the Direct Pro 24/96 Control Panel input strips. This button only affects the Compressor and EQ for that input channel strip. It does not allow recording of the REVERB. For information on how to record our Reverb, refer to the Master Reverb sec- tion of the manual.

Note: If you choose to record 96kHz audio, the Rec Fx button cannot be activated. All effects will be disabled.

If the REC FX button is pressed

The EQ and Compressor (assuming they are not bypassed) that are on that channel strip will be recorded into the corresponding recording device driver. This allows each of the 4 input channels to have their own effects separately recorded onto 4 different tracks.

In this case, the digital peak meter shows the value of the wet signal that is being sent to the computer. This is a post-fader meter so if you move the volume fader, the meter will move accordingly and affect the level of the signal that is being recorded. It will also affect the level of that track as it is sent to the MONI- TOR bus.

If this button is NOT pressed

The EQ and Compressor on the input channel strip can only be heard via the MONITOR bus should you be listening or recording the MONITOR bus. The input device drivers 1,2 Direct Pro & 3,4 Direct Pro will not record either the EQ or Compressor.

In this case, the digital peak meter shows the value of the dry signal that is being sent to the computer for recording. The volume fader changes the volume of that track and sends it to the MONITOR bus. This meter is before the fader (pre-fader) so if you move the volume fader, the meter will not be affected.
