Compatibility:
DakiOm Feedback Stabilizers work with
virtually any audio system with a conventional design (which covers
most consumer and audiophile equipment). However, please note the
following:
- WITH MA253/MA203/A203/QA203/HA203/MA103/A103/QA103/HA103, THE AMPLIFIER OUTPUT MUST BE ABLE TO HANDLE
A CAPACITIVE
LOAD OF UP TO 0.08uF. (Best results are obtained with amplifiers that can
handle a capacitive load of up to 0.33uF.) THIS IS TRUE FOR MOST CONVENTIONAL COMMERCIAL AMPLIFIERS. WHEN IN DOUBT (SUCH AS
SOME VACUUM TUBE,
OR UNCONVENTIONAL TECHNOLOGY), CONSULT THE MANUFACTURER.
- WITH R203/QR203/HR203/X203/R103/QR103/HR103/X103, THE PLAYER OUTPUT MUST BE ABLE
TO HANDLE A CAPACITIVE LOAD OF UP TO 0.004uF (0.006uF with MR253). (Best results are obtained with players that can handle a
capacitive load of up to 0.015uF.) THIS IS TRUE FOR MOST
CONVENTIONAL COMMERCIAL PLAYERS. WHEN IN DOUBT (SUCH AS SOME VACUUM
TUBE OR UNCONVENTIONAL TECHNOLOGY), CONSULT THE MANUFACTURER.
- WITH
F203/Fm203, THE PLAYER OUTPUT MUST BE ABLE TO HANDLE A CAPACITIVE LOAD OF UP TO
0.02uF. THIS IS TRUE FOR MOST CONVENTIONAL COMMERCIAL HEADPHONE
OUTPUTS. WHEN IN DOUBT (SUCH AS SOME VACUUM TUBE OR UNCONVENTIONAL TECHNOLOGY), CONSULT THE
MANUFACTURER.
Generally, Players with an output impedance less than 500 ohms are
compatible with the MR253/R203/QR203/HR203/X203/R103/QR103/HR103/X103. Players with an output impedance between
500 ohms and 2K ohms will work, but the effectiveness of the
Stabilizer may be degraded. Players with an output impedance greater
than 2K Ohms are not recommended. With F203/Fm203, player must be able
to drive headphone impedance of 16 to 160 Ohms.
- Some audio components do not use
Feedback circuitry such as various Class D amplifiers or "Zero
Feedback Amplifiers" and therefore do
not benefit from the Stabilizer. However, hybrid technologies such as BASH
amplifiers that have some Class D circuitry but have a regular Class
A/AB/B output stage will work with a Stabilizer.
- Using DakiOm Feedback Stabilizers
with incompatible equipment may produce unpleasant sound or cause
incorrect operation.

- 5 Watts/Channel maximum into 160 Ohm headphone impedance
- 10 Watts/Channel maximum into 32 Ohm headphone impedance
- 15 Watts/Channel maximum into 16
Ohm headphone impedance
Note: In a BRIDGED AMPLIFIER configuration, the Feedback Stabilizer box shares the output load between two of its internal stabilizer circuits. Therefore, together they can effectively handle twice the power (i.e.
A103 could handle a maximum of 600 watts total when bridged into a single 4
Ohm speaker, 320 watts total when bridged into a single 8 Ohm speaker, and so on).
Make sure you connect the Stabilizer Box so the output of each half of the bridge is
connected to a separate red wire of the A203/QA203/HA203/A103/QA103/HA103 and the black wire
must be connected to the common ground.
Maximum Span/Reach of Feedback
Stabilizers:
- The maximum span of the MA253/MA203/A203/A103/A103+/MA103 is
5.5 inches. If your system has two mono-block amps or the speaker terminals
of the amplifier channels are more than
5.5 inches
apart, you must use two A203/A103s or two MA253/MA203/MA103s. (Remember to tape off any
unused red
wires). The maximum span of the QA103/QA203 is 7 inches. The maximum span of the
HA203/HA103 is 8 inches. Extending the length of the amplifier
stabilizer wires with extra pieces of wire will
quickly diminish its effectiveness.
- The maximum span of the R203/R103 is 6
inches. The maximum span of the QR203/HR203/QR103/HR103 is 9 inches. If your player's RCA outputs are
farther apart, you
can use two R203/R103s or you may extend each R203/QR203/HR203/R103/QR103/HR103 input with up to 8
inches of cable. (We suggest using a plain RCA Y-Cable for the extension. They are
easy to obtain and are typically 6-8 inches long. Just tape off the
unused part of the Y Cable.)
- The maximum span of the X203/X103 is
16
inches.
- The maximum span of MR253 is 12.5
inches between RCA connectors (it is 16 inches long total). You may
add extension cables if needed but for best results try not to use
extensions.
