KV2’s 500 SERIES Installation Safety Instructions

To install the KV2’s 500 Series modules into a 500 series chassis:

1. Turn off the power to the 500 series chassis.
2. Unpack the module and ensure the rear connector is free of debris.
3. Align and slide the module into the 500 series chassis, ensuring the connectors on the back properly seat with the connectors in the chassis.
4. Install the included screws to secure the module to the chassis. Both metric and standard screws are included. Use the correct screw type for your chassis.
5. Power on the chassis.
6. Enjoy!

WARNING! Do not hot swap 500 series modules! Doing so can potentially cause damage to the 500 series module or chassis. Always power down the chassis when installing or removing 500 series modules.

TCL 500 SERIES Introduction

The TCL is a unique analog thermo audio compressor featuring a superior natural RMS detector and dynamic voice bass enhancement control. In another KV2 first its patented design offers an exceptionally musical and natural compression that is a component part of its real-time input, rather than a typical side fed gain reduction circuit attempting to either follow or anticipate compression demands. Its additional Bass balance control circuit allows the user to smooth out and minimise any proximity effects from a changing microphone position, giving the perfect voice color to every performance, from beginning to end. Featuring source intelligent attack and release times, whatever the dynamic content, with just a few simple steps the results from the 500 Series TCL are truly exceptional.

Application

• The TCL is the ultimate compression tool for various studio and live applications with instruments and voice.
• The TCL perfectly suits Musical theatre – giving consistency, richness and depth to head worn microphones.
• The TCL is ideal for corporate presentations – giving a full, warm, full voice timbre and allowing tone matching for lecturn and lavalier microphones.
• The TCL can be used live on many musical instruments, both classical and contemporary.

TCL 500 SERIES Controls

1. LIMITER
   Serves to set the maximum input level. Any subsequent levels above the set level are hard limited.
   This ensures that any connected devices further down the signal chain are not affected by an overloaded input The limiter’s active state is indicated by the limiter LED.

2. DRIVE
   This control sets the drive level for the input of the compressor’s gain reduction circuit.

3. LOW
   Serves as a low frequency enhancement circuit by rerouting some signal from the second in line thermo-compressor through a low pass filter, providing a full and warm bass enriched sound, even under compression.
   Select the required bass enhancement by sweeping the pot in a clockwise direction, where the center position presents a flat frequency response, with additional bass enhancement available beyond that point.
   The combined output of its signal path after gain reduction and the bass enhancement circuit blend, monitor and balance themselves perfectly in real- time to maintain the all important voice color within a 20dB range.

4. LOW-MID Switch
   This switch allows two alternate settings of the low pass filter frequency in the thermo-compressor LF enhancement circuit. This can be set to the operators preference depending on personal taste, microphone type and individual voice characteristics. (Male / female etc)

5. OUT
   Adjusts the output level.

6. METERS
   Output level meter – a 12 segment, 3 color peak reading meter serves to monitor the output signal level. If the red PEAK light flashes, the signal level is too high and should be reduced to prevent possible overload distortion.
   Gain reduction level meter – an 8 segment level meter displaying the amount of gain reduction performed by the compressor.

7. BYPASS
   Serves as a TCL module bypass.
   Please Note – In bypass mode all meters and LED indicators will still show the lastest operation mode, but the audio path is unaffected by any of the settings.

QD8 – 500 SERIES Specifications

MPA 500 SERIES Introduction

A revolutionary George Krampera 8-band Equaliser specifically designed to highlight a desired band without adversely affecting the overall sonic landscape. Whilst not intended for tuning out room modes, the frequency bands and filter types have been precisely chosen after extensive research, to perfectly align with the science of human hearing and our perception of achieving the ultimate spectral balance. In a Live scenario, faced with a number of different sources, program types, or performance genres at a festival or concert, the equaliser is very musical, intuitive and an exceptionally quick way to shape any mixed content to the sound you want to hear. In the studio, it can be either the simple enhancement of an instrument / vocal track, or the final mastering polish  to take an ordinary mix and make it something very special.

NOTE
As the QD8 is a stereo (two channel unit) it will require a series 500 Rack that facilitates dual channel input and outputs. It is also recommended to insert the QD8 as the last unit in the series 500 chain, directly before the amplifiers/speakers.

Application

• For use in Recording Studios as a master equaliser, single instrument, or group equaliser.
• Front of House PA system master equaliser, the unit is also equipped with line drivers designed to maintain audio signal integrity over long cable lengths (up to 200 m).
• Single stereo zone or dual mono system equaliser, to sonically match different fill speakers and zones with the main FOH PA when used in multiples.
• To reduce the harshness in some digital recordings, particularly around the 6kHz region.

MPA – 500 SERIES Controls

1. 8-Band Equaliser
   The Equalizer boosts or cuts frequencies at 40, 80, 120, 250, 500, 3000, 6000 and 15000 Hz by +/-15dB.

2. Output level meter
   A 12 segment, 3 color peak reading meter serves to monitor the output signal level. The signal should average around ‘0dB’. If the red PEAK light flashes, the signal level is too high and should be reduced to prevent possible overload distortion.

3. EQ ON switch
   8-band Equaliser EQ enable switch. When depressed, the EQ is bypassed.
   NOTE It is recommended to insert the QD8 as the last unit in the series 500 chain, directly before the amplifiers/speakers.
