Phoenix Audio DRS-2 - Stereo Class A Microphone Pre-Amplifier/DI User Manual
Page 5
The DRS-2 is capable of handling a huge input range,
from -70dB right up to 0dB, and STILL have 10dB of headroom. The output
stage can easily deliver +25dB!!! Please don't automatically believe the
DRS-2 is clipping!
For DI input:
Simply insert the input signal into the DI jack, and turn up the level using the Output knob
only, (remember, the Mic-sensitivity switch is not operable in the DI mode).
If the Green LED is Just lit, then the unit will be sending a level of 0dB to the output XLR,
and if the Yellow LED is lit, then it is sending +8dB to the output XLR. this is NOT the
maximum levels the unit will output, but is purely and indication" of level. If you want a
much "Hotter" output, then simply turn up the output level knob to whatever you need. You
can turn the output level knob to almost maximum without any fear of distortion in the output
stage.(This still leaves +10dB of headroom).
INPUT and OUTPUT connections:
The DRS is fitted with an XLR input on both the front and rear panels. These XLR's are
wired in parallel and both inputs are permanently active. (one does not disconnect if the other
is being used). The XLR's are industry-standard Pin 1 - Ground, Pin 2 - Hot, Pin 3 - Cold.
Both XLR's can be used at the same time (Microphone plugged into both inputs), this will not
cause damage to the unit. but the user MUST be aware of the following:
If both inputs are used together the two microphones will mutually load each other. This will
likely change the characteristics of both microphones.
If the +48V phantom power is button is engaged it will apply +48V to BOTH XLR's.
The DI input is a standard 1/4" (6.35mm) mono jack socket (wired Standard - Tip-hot,
Sleeve-Ground)
The Outputs of the units are on the rear of the unit and is available on both a 3 Pin XLR
(wired as the input XLR), and a Stereo 1/4" (6.35mm) Jack socket (wired Tip-Hot, Ring-Cold,
Sleeve-Ground).
Both output connections are wired in parallel and both can be used at the same time (for
instance, the XLR connected to external recorder, the Jack to monitor).
Also, "Y" cables and splitters can be used to send the output signal to various destinations at
one time.
Users should be aware that using both outputs together will mutually load the output
transformer of the DRS, and loading should not exceed a total of 200R.
