Frequently Asked Questions - TransY ART

What is the ART TransY?

The ART TransY is a two-channel discrete transistor FET-based compressor/limiter designed for live sound, recording, and mastering. It features a unique servo-controlled FET gain reduction circuit and a wide range of controls for musical compression.

How do I set the threshold on the TransY?

Start with the Threshold control fully clockwise (no compression). Slowly turn it counter-clockwise until the yellow (0) LED on the gain reduction meter lights. Then adjust to achieve the desired amount of compression.

What does the Link switch do?

The Link switch connects both channels for stereo operation. The detector signals are summed, and Channel 1's controls (Threshold, Ratio, Attack, Release, De-Esse, Output) become the master. This ensures identical processing of both channels to preserve the stereo image.

How do I use the de-esser?

The De-Esse control reduces sibilance ('s' and 'sh' sounds) when compressing vocals. Turn it clockwise to lower the threshold for a narrow band of frequencies around 6kHz, attenuating up to 16dB.

What are the power requirements for the TransY?

The TransY uses an external 48V DC power supply that accepts 85-250 VAC, 50-60 Hz. It comes with a locking connector and an IEC power cord. Ensure a proper ground connection.

Can I use unbalanced cables with the TransY?

Yes, you can use unbalanced 1/4-inch cables on the balanced inputs and outputs without damage. However, balanced connections are recommended to reduce noise. For unbalanced use, use a TS cable.

How does the bypass switch work?

The Bypass switch is a hardwire (passive) bypass that physically connects the input to the output, even when power is off. This allows the signal to pass through unaffected and simplifies troubleshooting.

How do I set attack and release times?

Attack time (0.5ms to 100ms) controls how quickly compression starts after a signal exceeds the threshold. Release time (50ms to 3s) controls how quickly gain returns after the signal drops. Shorter attack for tighter control, longer for more natural transients. Shorter release for more sustain, longer to avoid pumping.

What is the detector loop used for?

The detector loop is an insert point between the input buffer and the compressor detector. You can connect an equalizer to contour the compression response, or use an external signal for ducking applications (e.g., music fades when mic is active).

How do I obtain warranty service?

For warranty service within the USA, register online at www.artproaudio.com and request a Return Authorization (RA) number. Pack the unit in original packaging, include a note with the RA number, contact information, and a copy of the purchase receipt. Ship prepaid to the authorized service center.

Please retain this carton for use in transporting TransY when it is not installed in a rack, or in the unlikely event that the TransY requires servicing. The shipping carton should contain:

The TransY

The user's guide

48V Power supply

IEC power cord

AC Power Hookup

TransY has an external power supply designed to operate from 85 to 250VAC, 50 to 60Hz. Units manufactured for use outside of the United States have been modified to comply with the required electrical specifications for the country of use. Under no circumstances should the power cable be altered. If the cable becomes cut or damaged, discontinue its use and have it replaced before operating TransY.

The power source must provide a good ground connection, and the ground pin on the mains plug should never be defeated.

Analog Audio Connections

Audio connections to and from TransY are:

$$ \begin{array}{l l} \text {Balanced input: [XLR]} & \text {Pin 2 = Hot (+) , Pin 3 = Cold (-) , Pin 1 = Ground} \ & \text {[1 / 4 - inch] Tip = Hot (+) , Ring = Cold (-) , Sleeve = Ground} \end{array} $$

$$ \begin{array}{l} \text {Balanced output:} \ \quad \begin{array}{l} [ X L R ] \quad \text {Pin 2 = Hot (+), Pin 3 = Cold (-), Pin 1 = Ground} \ [ 1 / 4 - i n c h ] \text {Tip = Hot (+), Ring = Cold (-), Sleeve = Ground} \end{array} \end{array} $$

$$ \text { Detector output: } \quad [ 1 / 4 - \text { inch } ] \text { Tip } = \text { Hot } (+), \text { Ring }, \text { Sleeve } = \text { Ground } $$

$$ \text { Detector input: } \quad [ 1 / 4 - \text { inch } ] \text { Tip } = \text { Hot } (+), \text { Ring }, \text { Sleeve } = \text { Ground } $$

Unbalanced 1/4-inch cables may be used on the balanced inputs and outputs with no damage to TransY however, we strongly recommend users use a balanced connection whenever possible to reduce noise. We recommend using only high-quality cables equipped with the appropriate connectors.

REAR PANEL connections and controls

Balanced Inputs

The TransY provides both an XLR and 1/4-inch input jack. These jacks are balanced, but the 1/4-inch jack can be used with unbalanced signals by simply plugging in an unbalanced cable.

The inputs are designed for use with line level signals ranging from -30dBm to +20dBm. While it is possible to plug an instrument directly into the TransY, it is desirable to run the instrument into a preamp ahead of the unit. This will provide a stronger signal and will keep noise to a minimum. Microphones must connect through a microphone preamplifier (like the ART Pro MPA II) before connecting into the TransY.

NOTE: The TransY has a passive (hardwire) bypass. This means that the bypass works even if the power is off.

Balanced Outputs

The analog output of the TransY is available on both a 1/4-inch TRS balanced jack and an XLR jack. This output is transformer balanced. The output has a low impedance for driving long lines.

“0” on the output meter corresponds 0dBu (.775 VRMS) at the output jacks when the I/O switch is set to +4 and -10dBV when set to -10.

Detector Loop

The Detector loop is an insert point between the buffered input signal and the Detector of the compressor.

Connecting an EQ to process this signal can contour the compressor's response when gain reduction is present.

Connect an audio signal to the Detector Loop Input and have the TransY reduce gain when a signal is present to provide Ducking (see the APPLICATIONS section for more information).

Output Ground switch

The Output Ground switch allows you to disconnect the input ground from the output jack. This is useful in eliminating ground loops.

Fig. 1 - Rear Panel

FRONT PANEL CONTROLS and INDICATORS

Bypass Switch

The TransY BYPASS switch physically connects the input jack to the output jack on each respective channel (also known as a hardwire bypass). The analog signal still passes from input to output if the Bypass switch is in the out position, even when power is off.

Threshold Control

The THRESHOLD control sets the point at which the TransY will act on a signal. Turning this control counter-clockwise lowers the threshold (adding more compression to a signal). Turning this control clockwise raises the threshold.

Proper setting of the INPUT THRESHOLD control is dependent on the input signal. The easiest way to set this control is to start with the control fully clockwise. Slowly turn the control counter-clockwise (lowering the threshold) until the yellow (0) LED light on the COMPRESSOR ATTENUATION meter begins to light. Next adjust the control (either lower or higher) for the desired amount of compression.

Use the attenuation meter as a visual guide to the amount of compression applied.

Ratio Control

The RATIO Control selects the “amount” of compression applied to the input signal once that signal reaches or exceeds the threshold. This compression amount is expressed as a ratio of input to output. For example if a 4:1 compression ratio is chosen, for every 4dB over the threshold the input signal rises, the output level only rises by 1dB. In this case if the input signal increased 12dB over the threshold, the output level would only rise by 3dB.

In general, compression ratios of 10:1 and greater are considered "limiting". The TransY may be used as either a compressor or a limiter with all of the following:

In a mixer's channel insert points.

Between a microphone preamp and signal processors.

Between pre-amplified electronic musical instruments (synthesizers, guitars, bass, samplers, acoustic instruments with pickups) and other line-level equipment.

Fig. 2 - Front Panel controls

Attack Control

The ATTACK control sets the time it takes the Compressor/Limiter to respond to increases in signal level (by reducing gain) and shape the front end of the dynamics envelope.

One example is to listen to a snare hit and adjust the ATTACK control. A short attack makes the snare sound “thin”. As the attack time goes longer (the knob is turned clockwise) more of the thump in the compressed snare can be heard. The downside is that this creates an overshoot, or “transient”, the length of which is the time set by the ATTACK control.

Overshoots less than 1 mSec. are very hard to hear even when they are clipped. If the ATTACK is set too fast, the gain may be reduced too much and thereby create a pumping sound ^1 .

Release Control

The RELEASE control sets the time the Compressor/Limiter takes to increase the gain after the input level drops.

Longer settings maintain the dynamics of the input signal, while shorter settings reduce the dynamics. Shorter settings will also increase the apparent reverberation, and at extreme gain reduction settings, lead to breathing artifacts ^2 .

De-Esse Control

De-essing refers to reducing the "s" and "sh" sounds level that is be increased when adding compression. The TransY De-esser control lowers the threshold of compression of a narrow band of frequencies to maintain a more natural level of sibilance as you increase compression.

Output Control

The OUTPUT control adjusts the Overall gain of the TransY.

The Channel 1 knob always controls the output level of Channel 1, but can also serve as a master output level when the Link Mode is active.

Gain Attenuation LED Meter

The attenuation meter displays the TransY compressor/limiter action. The meter covers a very large range while offering high resolution. The yellow (0) LED illuminates when the input signal reaches or exceeds the compressor detector threshold setting (Threshold control) and results in a reduction of 1 dB or more.

Level LED Meter

This meter displays the signal level present at the output of the unit. "0" on the meter corresponds to 0dBu (.775 VRMS) at the output jacks when the I/O switch on the rear panel is set to +4 and -10 dBV (.194 VRMS) when set to -10.

Meter Source switch

This switch selects the source for the LED level meter. When "out" the output signal is monitored. Depressing the switch displays the signal level present at the input of the unit.

The Link Switch

The two channels of the TransY can be configured for stereo operation by depressing the LINK switch. Link Mode connects the gain reduction of the two channels together for stereo operation. The Detector signals of the two channels are summed so either channel's signal can trigger gain reduction. Channel 1's controls (THRESHOLD, RATIO, ATTACK, RELEASE, DE-ESSE, OUTPUT) become the master and Channel 2's controls are ignored. Link Mode ensures that each channel of the stereo input signal is processed identically to prevent any shifting or distortion of the stereo image.

All of the switches (Bypass, Meter Source, +4/-10, Ground Lift) remain independent in link mode.

Power

The POWER switch turns the power on and off to the unit. The TransY should be turned “on” with all monitor levels turned down to protect against any thumping caused by power up. Likewise, the TransY should be turned off only after turning all monitor levels down. Power on the TransY before any monitoring outputs or power amps are turned on.

If the TransY fails to power up when the POWER switch is turned on, check to see that its power cord is plugged into an active outlet. If the unit still fails to operate properly, turn it off and unplug it.

APPLICATIONS

Compressor/ Limiter

The main application of the TransY is to control the dynamic range of an audio signal. Plug a line level (post preamplifier or other gain stage) source into either input, and set the threshold and output controls to provide the desired amount of compression to the input signal.

To keep the compression effects to a minimum, adjust the THRESHOLD and RATIO controls such that the Compressor Attenuation meter reads 10dB or less.

Stereo Mix and Mastering

Because of its low noise and excellent tonal qualities, the TransY is ideal for processing mixes when recording. Used as a mastering device, the TransY is capable of adding volume and impact to the overall signal level. The TransY is ideal for live use as well.

Putting the unit into link mode simplifies the control usage while maintaining the stereo image of the source material. The knobs on Channel 1 override CH2's controls.

The TransY really does a good job of controlling the peak content when setting the attack and release short and the Ratio to :1 . Make sure not to set the Threshold too low however. Only 6-10 dB indicated on The Compressor Attenuation meter is required to maximize the level of digital recordings.

Vocal and Instrument Leveling

The musical nature of the TransY makes it ideal for use on a wide range of instruments and vocals. Place the TransY into a channel insert, after a preamplifier, or in line with the direct output of a mixer channel. Adjust the controls of the TransY to achieve the desired amount of compression.

A good starting point for speech is a Ratio of 2:1 and gain reduction of 3-9dB. Adding sustain to instruments requires more aggressive settings for ratio (start at 4:1) and threshold. Gain reduction in the 15dB range is not uncommon.

Vocal processing may require tailoring of the detector response to prevent excessive sibilance. Rotate the De-esser control clockwise to reduce vocal sibilance.

Ducking

One application of ducking is muting the background music whenever someone talks into a mic. Simply connect the background music to be ducked to the audio input of the TransY and connect the line level buffered mic signal to the Detector Loop jack. Set the RATIO control to :1 Adjust the THRESHOLD control for the amount of muting required when someone is talking into the mic. Set the ATTACK control to 1 to 2 mSec to guarantee the music fades off quickly. Adjust the RELEASE control to set the time it takes to fade the music back in after there is no mic signal.

For a stereo music source, depress the LINK switch.
