Description
Introduction
Thank you for purchasing a Discreet Acoustics module. The Discreet
Acoustics Compact Series comprises four gooseneck microphones, one flown
micro-phone, and dedicated accessories for every application and every type of
venue.
Microphones Refer to figs. 9 to 14.
- CGN 99 C/S (order no. 2965H00110): 380-mm (15-in.) cardioid gooseneck microphone with integrated DPA XLR phantom power adapter and external foam windscreen. CGN 99 H/S (order no. 2965H00120): 380-mm (15-in.) hypercardioid gooseneck microphone with integrated DPA XLR phantom power adapter and external foam windscreen.
- CGN 99 C/L (order no. 2965H00130): 576-mm (23-in.) cardioid gooseneck microphone with integrated DPA XLR phantom power adapter and external foam windscreen. CGN 99 H/L (order no. 2965H00140): 576-mm (23-in.) hyper cardioid gooseneck microphone with integrated DPA XLR phantom power adapter and external foam windscreen.
- CHM 99 (order no. 2965H00150): cardioid flown microphone with spring clamp and 10-m (33-ft.) special cable with DPA XLR phantom power adapter.
Windscreen (2965Z2001)
- Always use the supplied windscreen (unless it would be too visually obtrusive). It protects the microphone from dust and moisture and reduces pop and wind noise to a minimum.
Optional Accessories
- B 18 battery power supply for all Discreet Acoustics Compact microphones.
- PS3 F-Lock panel mount socket for all Discreet Acoustics Compact gooseneck microphones (not for CHM 99).
- H 500 shock mount for all Discreet Acoustics Compact gooseneck microphones (not for CHM 99).
- H 600 shock mount for all Discreet Acoustics Compact gooseneck microphones (not for CHM 99).
- SA 60 stand adapter for all Discreet Acoustics Compact gooseneck microphones (not for CHM 99).
- ST 1, ST 45 table stands for all Discreet Acoustics Compact gooseneck microphones (not for CHM 99).
Microphone Applications
Note that both the maximum working distance and the area covered by the microphone depend on the pickup angle. The smaller the pickup angle (hypercardioid), the longer the maximum distance between the talker and the microphone and the smaller the area covered by the microphone. Whether a cardioid or hypercardioid capsule will give the best results therefore depends on the specific application situation).

Installation and Connection
Introduction
All Discreet Acoustics Compact microphones are condenser microphones and
therefore require a power supply (phantom power). The microphones have been
designed for connection to microphone inputs with 9 to 52 V phantom power. To
connect Discreet Acoustics Compact microphones to inputs without phantom
power, refer to Section 4.4.
4.2 CGN 99 …Gooseneck Microphones Refer to figs. 9 and 12.
-
Use the optional PS 3 F-Lock panel mount socket to install the microphone in a tabletop or an optional SA 60 stand adapter to mount the microphone on a floor or table stand.
Note For even better vibrational noise rejection, you can fix the microphone to the tabletop with an optional H 500 or H 600 shock mount. -
Use a shielded cable to connect the microphone to a microphone input with phantom power.
-
If the phantom power on your mixing console is switchable, switch the phantom power on. (Refer to the instruction manual for your mixing console.)
The microphone is powered directly from the phantom power source on the console.
CHM 99 Flown Microphone
-
Before installing the microphone, straighten the cable by carefully pulling it through your fingers. Make sure not to buckle or twist the cable. Let’s hang for 1 day to untwist.
-
Fasten a hook to the ceiling, use an existing hook, or stretch a fishing line across the hall.
-
Pass the cable through the hook or over the line so that it will hang at the desired height.
Important! Do not tie a knot into the cable to hang it on the hook. This may cause the cable to twist and misalign the microphone after a while.
-
Hold the cable with one hand and turn the microphone carefully into the desired position.
Note:
- The cable on the CHM 99 will twist as the ambient temperature changes, e.g., in the heat generated by spotlights.
- The angle of twist depends both on the ambient temperature and the cable length. The shorter the cable, the smaller the amount of twist.
- If you use spotlights, be sure to turn them on before aligning the microphone.
- When you turn the spotlights off, the microphone will rotate out of alignment. Upon turning the spotlights back on, the microphone should rotate back into its original position.
To stabilize the microphone,
- Leave an appropriate length of fishing line through the eyelet on the spring clamp of the CHM 99.
- Fix the fishing line to two opposite walls so as to create just enough downward pull to steady the micro-phone laterally.
Applications
Audio Connection
- Use a shielded balanced cable to connect the microphone to a microphone input with phantom power.
- If the phantom power on your mixing console is switchable, switch the phantom power on. (Refer to the instruction manual for your mixing console.)
The microphone is powered directly from the phantom power source.
Connecting to Inputs without Phantom Power
- If your mixer has no phantom power, insert an external phantom power supply between the DPA phantom power adapter and mixer input. We recommend the optional B 18 power supplies from AKG. Using any power supplies not recommended by AKG may damage your microphone and void the warranty.
- You may also consider having a qualified technician retrofit a phantom power supply as per IEC 61938 to balanced or unbalanced mixer inputs. The IEC 61938 standard specifies a positive voltage of 12, 24, or 48 V on the audio lines versus the cable shield.
Balanced Inputs
If your equipment inputs are grounded or transformer-less, wire either capacitors or extra transformers into the audio lines as shown in fig. 9 above to prevent any current leakage into the input stage.
Unbalanced Inputs
Table 2: Standard values for Rv and 2 x Rv
- To satisfy the IEC 61938 symmetry requirement, make sure the actual values of the two resistors 2 x Rv do not differ by more than 0.5%!
Bass Cut
The DPA phantom power adapter is equipped with a bass-cut filter to
minimize low-frequency noise.
- Unscrew the fixing screw on the microphone or DPA phantom power adapter.
- Pull the circuit board out of the case WITH CAUTION – so as not to break the internal leads.
- To activate the bass cut filter, plug the jumper J1 into the central contact pair on the circuit board.
