Yes, you can install Samplitude SE 9 Windows 7. When you try to install a version of Samplitude prior to version 11 on Windows 7 you may be prompted with an error message indicating a wrong operating system. If so, simply navigate to install.exe on the installation DVD, right-click on install.exe and set compatibility mode. Installation should now complete as expected.

Note: Samplitude SE 9 package is not available in all regions or products. Contact your local dealer for the specific software included with your purchase.

V-Balanced I/O is a World-First technology developed by the award winning Infrasonic development team of SIMS Audio.

V-Balanced I/O allows Quartet to be used as a balanced 2in/2out interface, instead of as an unbalanced 4in/4out interface. The I/O-type selection is done through a simple click on the "Balanced Link" button of the driver control panel [ Show ].

When shifting to Balanced I/O, Headphone output, MIC, and INST input will all shut down. You can then monitor the pure, high quality balanced signal without upgrading your hardware. This feature was first made available in December 2008 with driver version 1.18.4. (See drivers page). Select Windows Drivers / Quartet Tab.

A Balanced Signal allows the use of Reversed Phase Theory to avoid HUM or RF noise that comes within cable transfer. It is a method exclusive to Pro-Audio equipment, and used most often in long distance signal transfer (i.e. long cables), situations that are sensitive to noise and alterance of sound.

The red indicator in clock source means "Lock bit.” It indicates the state of the S/PDIF connection. It turns on when the S/PDIF connection is "Stable." When the indicator is turned on you can select the clock source in “internal, digital in, or word.”

Unfortunately, two or more Quartets cannot be installed in the same PC.

The lowest stable latency is 1ms at 44.1kHz/24bit and 1.33ms at 96kHz/24bit with 80% CPU load.

If you have connected the audio output of the TV tuner card to the line (3/4) input of Quartet, please attach H/W input 3,4 to WDM input 1,2 in Free Mixer.

Certainly. Quartet will accept dynamic microphones with a simple unbalanced TS jack. And if the output signal of the microphone is insufficient, you can apply +60dB amplification via a jumper on the soundcard.

No, there is no measurable delay between line input L/R channels.

Please see soundcard comparison chart.

Use caution when plugging in your microphone to the Quartet

TRS Jack (above)

1. Sleeve
2. Ring
3. Tip
4. Insulating rings

Please follow the instructions and proceed carefully. If you do not follow the instructions, the product could be critically damaged.

You must turn off the system before making any connection change to the microphone. If not, it could cause a fire or electric shock that may be harmful to you and your product.

Turn off your computer before you connect the microphone to Quartet. Make sure the microphone is plugged in properly before you turn your system back on. If you connect the microphone when the system power is on, it may cause electric shock that ccould damage the QUARTET critically.

The QUARTET is a PCI card interface with no XLR input. To use a microphone with a XLR plug, you can use TRS 1/4" converter jack. Since the TRS jack contains the tip, ring, and sleeve parts linearly, it may cause electric shock or short circuit if you connect/disconnect it while the system power is on.

SETTING YOUR QUARTET'S GAIN JUMPER CORRECTLY

Usually PCI audio interface cards do not come with a built-in microphone preamp.  Even cards that come with preamps don’t have gain adjustability, or if they do it is digitally controlled.  Digital gain adjustment will add noise to the output because the gain is increased digitally.  However, the QUARTET PCI interface has a function that allows the user to manually adjust the gain on the hardware itself, instead of digitally.

The following article is instructions on how to properly set the jumper of your new QUARTET PCI interface.  Jumper settings can be optimized to best suit your microphone and source.  Once the jumper is set, manual gain adjustments are available thru the control panel.  

If your jumper settings are not correct, you may have excessive noise and/or distortion in your recorded tracks.

Gain Amplification


There are three different jumper options on the QUARTET (+20dB, +40dB, and +60dB).

The above image illustrates the jumper positions from left to right (+20/+40/+60dB).

You can adjust gain in control panel (0~+18dB), but it is better to adjust jumper setting than control panel setting. You will get less noise and better sound quality by adjusting jumper.

Ideal Uses for Each Jumper:

+20dB – Use when the microphone sensitivity is high and you are recording a loud source (condenser microphones)

+40dB (Recommended setting) – Use this setting when the microphone sensitivity is average (dynamic microphones)

+60dB  - Only use this setting with microphone that have very low sensitivity/output (ribbon microphones)

Once your jumper is set in the correct location, it is possible to electronically control the gain from the control panel up to +18dB (0~+18dB).  

Pad



The Pad is a switch which further reduces the gain of the microphone preamplifier.  It can be used in many situations such as when recording a high SPL source, so that your preamp does not clip.   Primarily, the pad is used with a condenser microphone (or other high sensitivity microphones) when you are recording high SPL sources such as a drum kit or loud guitar amplifier.  It is also useful when recording a dynamic/ribbon microphone at very close proximities.  

The PAD with -20dB three thing 20dB (about 10 boats) degree input of big level clip Ping it will be able to record without because is becoming.

The image on the left is the pad on; and the right side is Pad off.  The QUARTET is delivered from our factory with the pad engaged.

It is recommended to change the pad jumper settings to take advantage of your Quartet.  It can often times correct a shortage of gain when using a dynamic microphone or sensitivity problems when you use condenser microphones.
