The SD5 does not have a 2nd mic input, but provides for using a 2nd mic by way of an "optional adapter". Some kind of input splitter, I guess. Does anyone know exactly what that adapter is and where to obtain one?

Glenn, I will find out.

1/4" male (mono) to two 1/4" femail (mono).

Thanks,

I had one at the house and it works fine.

The 1/4-inch mono/splitter will only work when using identical mics, and with the correct impedience. If they are low impedience mics, you could overload the mic input circuit. In most instances it's best to use an inexpensive mixer such as the Alesis Multi-Mix6-FX. Not only do you eliminate overload problems, but additionally, you can set the effects for each individual mic.

Good Luck,

Gary, that's true to a point, but the SD5 has separate volume, effects and e.q. for each mic, so is more versatile.

Thanks Don,

Good information.

If those are mono 1/4" inputs, does that mean they only work with high impedance microphones?

AFAIK, you can't use a low impedance Mike in a high impedance input without a transformer...

Something doesn't make sense. AJ said a a/4-inch mono splitter that connects to a pair of 1/4-inch monos. If this is the case, then it's a single input--not dual. The mics would be wired in paralell, which means both would be using the same effects and volume control.

Now, if the adapter was a 1/4-inch stereo male (TRS) that split to a pair of 1/4-inch mono jacks, then you could plug in two mics and control each mic individually. I don't have a schematic of the keyboard, so I cannot determine how the circuit is wired.

Good Luck,

Gary

Gary, I see it the same way. Both signals would be merged before they could be separately controlled. The SD5 does have built in software for controlling each of the 2 mics, with the single input. I'll give it a try tomorrow.

MICRO INPUT: Unbalanced _'' mono audio jack input for two microphones, (if a stereo-mono adapter is used). The Micro Input signal can be processed
by the inner Vocalizer of the SD5 and by the global effects. Without the adapter, only one microphone can be used.

The SD5 can use two separate microphones if an optional adapter is utilised to divide the stereo input into two microphone inputs. Input Mic 1
is the only one that can exploit the built-in Vocalizer plus it is provided with a separate audio output to allow the lead voice signal be processed
with an external mixer. To use both microphones correctly, you have to adjust the input gain using the dedicated cursor on the front panel
to reach an ideal noise signal level. To check if this level is correct, simply sing or speak into the microphone while adjusting the cursor and
listen to the result. If the gain is too high, the audio signal would be unpleasantly distorted and if the gain is too low, the signal will be disturbed
in proportion with the quality of the cable and the microphone. For these reasons, it is better to spend a little bit more for a quality dynamic
and sturdy microphone and strong connection cable.
Note: Some other aspects must be remembered when using a microphone:
�� Always connect the microphone with the volume of the SD5 at zero, with the gain at zero and the amplifier turned off.
�� Keep the microphone away from the speakers as there could be Larsen/feedback effects, which could seriously damage your PA.
�� In small rooms it is preferable to use a microphone with hypercardoid diagram to avoid Larsen/feedback effects.
�� Keep the microphone on a very solid rod to avoid mechanical noises interfering with your voice.
�� Keep the microphone cable away from power supply cables and lines.
�� When you connect all your equipment remember that the speakers and the amplifier are always the last to be turned on and the first to be
turned off.
MICRO EDIT
The parameters of the microphone are stored in the Micro (Vocalizer) menu, which
is pulled-up using the dedicated button on the panel of the instrument. The parameters
relative to the microphone are correlated to the relative function push buttons
and can be saved in a Registration.
F1 Level 1: This specifies the volume of the microphone on input Mic 1.
Once the parameter has been selected using the function
push button, the value is then varied using the DATA CURSOR
(Left and Right) buttons, which if pressed together at
the same time reset the value.
F2 Level 2: This specifies the volume of the microphone on input Mic
2. Once the parameter has been selected using the function
push button the value is then varied using the DATA
CURSOR (Left and Right) push buttons, which if pressed together at the same time reset the value.
F3 Pan 1: This selects the position on the stereo front of the microphone on input Mic 1. The signal of the microphone is set in the
middle when the parameter shows two dashes (- -). The value is modified using the DATA CURSOR (Left and Right) push
buttons (which if pressed together at the same time set the signal back in the middle).
F4 Pan 2: The same as F3 Pan 1 but for the microphone signal on input Mic 2.
F5 Music Vol: This balances the microphone signals with the sound generator of the SD5. The value is modified using the DATA CURSOR
(Left and Right) push buttons which, if pressed together at the same time, set the value back at maximum. If the level of
the two microphones is not sufficient to stand out compared to the SD5, it is useful to remember to reduce this value.
F6 Echo 1-2: A delay can be set on the two microphone signals, the intensity of which is controlled by this value. To switch between
input Mic 1 and Mic 2 press the function push button F6 cyclically. The value is entered using the DATA CURSOR (Left and
Right) push buttons which, if pressed together at the same time, reset the value.
F7 Reverb 1-2: The same as F6 Echo 1-2, but for the reverb for each input.
F8 Pitch Shift: This only affects the signal of the microphone on input Mic 1 and is used to transpose the notes sung in the microphone
in steps of semitones. When the values are excessive the sound of the voice is distorted. This effect is one of the
Vocalizer features. The value is increased or decreased using the DATA CURSOR (Left and Right) push buttons which, if
pressed together at the same time, reset the value.
F9 VOCALIZER: This opens the control menu of the Vocalizer. Refer to the next chapter for further explanations on this subject
F10 Active/Inactive: This enables or disables the microphone inputs. If they are connected but not being used, it is a good rule to disable the
inputs to avoid disturbing noises.
EXCLUDING THE EFFECTS WHILE TALKING
One of the most frequently complained problems of musicians is that of being able to exclude the effects from the microphone signal when
talking to the audience.
The SD5 solves this problem with the TALK function that can be activated with the TALK key on the panel of the instrument. When you press
the TALK key, all the effects applied to the microphone will be automatically excluded. To restore the previous configuration, simply disable the
TALK function by pressing the TALK key again.

Thanks Fran,

Now it makes sense. There is a stereo jack in the back of the keyboard, which permits a pair of unbalanced, or single balanced mic to be plugged into the keyboard. I guess AJ had his adapters mixed up. And, Radio Shack doesn't sell a stereo to two-mono adapter plug, but they do sell adapter cables that can be used for the same purpose.

I tried with the simple splitter... doesn't work. It accomodates both mics but no separate control. Like mixing yellow and red, you get orange and that's it. You can only control the mixed orange.

AJ, what's the "optional adapter" I need... help!

Glenn

Glen,

I'll look up the correct adapter for you later tonight. The one that AJ recommended WILL NOT WORK!

Gary

The one I have works. I'll check it out when I get home.
There is only one jack. The splitter is necessary.
DonM

What do you do if you have the splitter? Use two high impedance mikes, or run transformers on low impedance ones?

It all seems very much a kludge...

Here's the cable that should work.


In addition to the cable you'll need a pair of RCA to 1/4-inch mono adapters, which is also available at Radio Shack. I have a couple of the adapter plugs here, but I cannot find the Radio Shack part number for them. Their were two in a pack and sold for about $6.99.

Good Luck,

Gary

I have always used lo imped mics with an unbalanced 1/4" cable when ever I use a built in arranger keyboard mic input. I hear nothing that suggests that I need a transformer. In some inputs, the gain structure will not support a HiZ mic, but my Yamahas and my Korg do just fine with out the need for transformers.

I guess the trick is to use the shortest cable you can get. Although the gain might be sufficient to get it to where you need, the thing you lose with unbalanced inputs is the ability to reject induced noise and interference. But keep your cables VERY short (basically, straight from the mike to the input, no extra at all) and this shouldn't be the problem it might be using 25'+ cords...

GlennT.

I thought you simply wanted to use the SD5 gain to control both.

To use the SD5 software to control 2 mics independently (MIC1 and MIC2), you will need to have an adaptor as such (One 1/4" Stereo male output with TWO 1/4" Mono Female inputs). Both mics should be identical.

Hope this helps.

Thanks,

AJ

ZZounds has a version of this cable made by Hosa for the cool price of $5.95 ( and another $6.99 to ship ).

Thanks, guys. The ring/tip Hosa splitter should do the job.

The one I have is Radio Shack. Two mono females to one stereo male.
DonM

That's the cable Don. I have one too, but I couldn't find it on their site anymore.
