Provides 48v phantom power to microphones. Overall gain to restore the apparent program levelīalanced or unbalanced Hi-Z input for instruments We suggest you try it and make your own judgment. The silk button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance. Much could be written about this feature, suffice to say, that it gives a subtle option to enhance sound quality in the direction of vintage modules. By adjusting the phase in the 517, the musician or engineer can find the absolute best mic position without regard to the phase relation to the direct signal. A bassist, using both direct and miced signals can blend the two into a single output, using the vari-phase to reach an optimal alignment. This technique is also extremely useful when combined with the internal blend control on instruments. By using the variable phase adjust, the direct signal can be phase rotated until the signals are naturally aligned.
This control is useful any time two signals derived from the same source are combined.įor instance, even with careful placement, the combination of close miced drums and overheads, can often yield hollow sounding results. In addition to the standard polarity reverse, the 517?s vari-phase control may be used to adjust phase incrementally. An LED light indicates when the compressor is active.
To set the compressor, simply dial the threshold control down until the desired amount of compression is achieved. By default, the compressor is set to a fixed 2:1 ratio with fixed attack and release. This technique could also be used to create a single, mixed output of a guitar and vocals.īased around a new LDR (light dependent resister) design, the 517?s opto-coupler compressor has been simplified to a single threshold control with auto make up gain. To compress the blended signal, the internal compressor jumper must be set to the blend path (this is the default setting). The blend control is used for mixing direct and amplified signals to achieve the desired tonal blend between the two sources, and the variphase is used to minimize or extenuate phase cancellations between the two signals. To achieve this, use the DI for the instrument’s direct signal and the mic preamp for the speaker cabinet signal. Used as a single channel device for instruments, the 517 can be used to phase align, combine and compress direct and amplified signals. The separate instrument amplifier includes 30dB of gain, a ground lift, variable phase and an instrument Thru connection. The Mic Pre also incorporates a polarity reverse switch and phantom power. The 517?s Mic Pre includes 66dB gain, and is based on the Portico 5017 design.
