Cascade
Ribbon Microphones and 48v Phantom Power
Cascade Ribbon microphones are Phanton Power safe.
The signal path from the ribbon is
wired so that it only flows one way,
which is out, via the transformer.
Connect your XLR
microphone cable to a pre-amp with matching PIN-OUTS. The PIN-OUT
configuration listed below is the Industry Standard for microphones, XLR cables and processing hardware.
Balanced Male/Female XLR PIN-OUT configuration:
-
PIN 2-HOT/POSITIVE/HIGH
-
PIN 3-COLD/NEGATIVE/LOW
-
PIN 1 Ground
Please Note:
CAUTION
USE OF PATCH BAY:
Disengage the Phantom Power prior the making an insert/patch. If the
Phantom Power is engaged while inserting a TRS 1/4" connector the ribbon will be damaged and
will require
replacement. Be sure the Phantom Power has had sufficient time to
ramp down before making an insert.
Summary of requirements for Cascade
Ribbon microphones and Phantom Power
1). XLR cable must be configured to
the industry standard.
2). XLR cable must be in good working
condition.
3). When using a patch bay, ramp down
the Phantom Power before making an insert/patch
Use of a high quality XLR cable is
recommended.
There is no front or back-side on a
Cascade ribbon microphone.
The ribbon placement is
symmetrical
If you find that your Cascade
ribbon microphone is out of phase with another microphone, simply
turn the microphone around and operate from the other side. The
Cascade ribbon microphone houses a hand-tuned element that
incorporates the legendary symmetrical ribbon design. This design
offers a true figure 8 pattern. The corrugated aluminum membrane
itself is positioned in the center from front to back, thus
producing a balanced audio input signal to both sides of the
ribbon assembly. This design is very useful when executing a
mid-side or Blumlein recording set-up and also great for live
stage use.
Wiring scheme:
Two leads (positive and negative) output from the
ribbon motor to the inputs (positive and negative) of the step-up
transformer.
Going from the ribbon motor:
- The output/positive lead is connected to the
ribbon block and then connects to the input/positive side of the
transformer.
- The output/negative lead is connected to the
rear of the ribbon assembly via a ground strap and then
connected to the input/negative lead on the transformer.
Going out of the transformer:
- The output/positive lead is connected to pin
2 of the XLR.
- The output/negative lead is connected to pin
3 of the XLR.
Pin 1 is grounded with a jump wire to the XLR
ground on the XLR connector.
