User manual DIGITECH VTP1

[. . . ] WARNING FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING: Water and Moisture: Appliance should not be used near water (e. g. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. POWER SOURCES: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. [. . . ] DigiTech liability under this warranty is limited to repairing or replacing defective materials that show evidence of defect, provided the product is returned to DigiTech WITH RETURN AUTHORIZATION, where all parts and labor will be covered up to a period of one year. A Return Authorization number may be obtained from DigiTech by telephone. The company shall not be liable for any consequential damage as a result of the product's use in any circuit or assembly. DigiTech reserves the right to make changes in design, and make additions or improvements to this product without incurring any obligation to install the same on products previously manufactured. The XLR connector on the top is a balanced input capable of receiving +4 dBu or -10 dBv signals. The 1/4" phone connector on the bottom is also a balanced +4/-10 input using the TRS connecting scheme. This requires a cable with "stereo" phone jacks to be used as a balanced input. It can also be used with an unbalanced source using a standard two conductor cable. If you plug a connector into the phone jack input, this will override anything plugged into the XLR input. ··· 4 ··· INSERT LOOP These connectors allow you to insert another processor such as a compressor or de-esser into the signal path. You would insert the processor into this loop to place it in the path leading to the digital output of the VTP-1. Both the SEND and RETURN are balanced TRS jacks with +4 dBu nominal sensitivity. SEND The audio signal produced at the SEND output is taken from a point in the circuit after the VTP1's tube and EQ stages. You can run a cable from this jack to the input of the external processor. Inserting a jack here will not interrupt the analog or digital audio output. This is to allow the SEND to be used as a direct post-preamp output that bypasses the main output stage of the VTP-1. RETURN Connect the output of the external processor back to the VTP-1 through this jack. An audio signal returning here is passed along to both the analog and digital outputs. DIGITAL OUTPUTS The VTP-1's digital output allows you to connect directly to a DAT recorder or digital multitrack via their digital input. You can completely bypass your mixing console when recording a voice or instrument through the VTP-1. By connecting a microphone or line level instrument to the input of the VTP-1, then from the digital output directly to your recorder you keep the signal path as pure as possible. If you have digital effects in your system and digital mixdown, your audio signal will only have to be converted back to analog when it's finally played on a CD player in someone's home. The VTP-1's digital output is offered in two standard stereo formats: AES/EBU and S/PDIF. [. . . ] The following graphs illustrate the Lo Mid and Hi Mid equalization curves at various cut, boost and center frequency settings. ··· 7 ··· LO MID EQ plot HI MID EQ plot Boosting frequencies adds gain and you may find that this lights the CLIP LED. If this occurs, reduce the level with the PRE GAIN control or POST TRIM. EQ In/Out switch This switch removes the entire EQ circuit from the signal path. This is useful if you want to confirm that your EQ modifications are an improvement on the non-EQ'd signal. [. . . ]
