Purple Audio Sweet Ten Rack with Action FET and Biz Bundle

Simply put, your 500 series modules will perform at their highest level in the Purple Audio Sweet 10 Rack. Audio performance improvements are considerable. The Sweet Ten top, side, and back panels are finished in trivalent yellow chromate cold rolled steel instead of painted steel for improved grounding and shielding. Purple Audio ground plane motherboards provide additional grounding. Additionally, the rack motherboard has frequency bypass capacitors at each slot to improve filtering, especially for modules with DC/DC converters.

Functionally, the Sweet Ten offers 2 inputs and 2 outputs per slot. Many Purple modules already take advantage of second output and our Moiyn mixer module will use the second input to allow for stereo balanced source injection. Future uses of these connectors include fader loops on future modules as well as a few surprises!

FEATURES:

• Ten 500 Series spaces for your favorite modules
• Two inputs and Two outputs per slot (one XLR and one TRS in/out)
• Made from zinc plate cold rolled steel for improved grounding and shielding
• Made with a Purple Audio-designed switching power amp to ensure clean sound through all of your modules

The Purple Audio Action features a constant impedance 600 ohm input attenuator feeding the input transformer, just like their MC77 units. This makes the input more resistant to overload by hot signals. After the input transformer, the signal is attenuated by the same gain reduction FET as in the MC77. The attenuated signal is buffered by our class A KDJ3 opamp, which feeds the output fader. Lastly, the Class AB KDJ4 output opamp drives our custom hexafilar nickel and steel output transformer. The total gain (with no attenuation) is 45 dB, just like the MC77.

Attack and release times cover a broader range than the MC77, which can cause distortion… which may or may not be what you are looking for. Use at extremes with caution. The ratios are the same as the MC77, and the threshold moves up as the ratio goes up, just like the MC77.

Stereo linking is accomplished by cross connecting pins 3 & 6 on the edge connector. On the Purple Sweet Ten Rack, there is a second output 1/4″ that can be used to link two Actions. The link is accomplished using a TRS to TRS cable with tip on one TRS connecting to RING on the other TRS and vice versa. Plug in the cable, flip the front panel switches and you are linked. Non-Purple racks do not have an easy way to connect pins 3 and 6, and will need modification to link two Action units.

FEATURES:

• Input attenuator feeding input transformer
• Output level control
• Input and output tricolor LED metering
• Eight LED GR metering
• Five ratios including “All buttons in” mode
• Attack and Release controls
• True Relay Bypass
• Stereo Linking
• Compression on/off switch
• Discrete signal path
• Over Current Resettable Fused

The Purple Audio Biz is a unique sounding, three amplifier, discrete microphone preamp module. The smooth Gain control helps you dial in the sound you want. If the output level is too high (the Class AB output opamp can pump out up to +27 dBu), you can ride the level down with the separate level control.

Pressing the “Dual” switch splits the gain between two Class A opamps, enabling up to 75 dBu of clean gain, making the Biz a perfect match for ribbon microphones.

With different Gain, Level, and Dual settings the Biz can produce an infinite variety of tonal variations with the same amount of output level. The front panel DI helps you record instruments and line level sources with unrivaled clarity and punch.

Two LEDs clearly indicate signal level for the gain and output stages at a glance, turning green to indicate signal present, yellow for 10 dB below clipping, and red for clipping. The Biz uses two KDJ3 opamps and one KDJ4 opamp.

FEATURES:

• Output level control
• Input and output tricolor LED metering
• Mic / Line switch for rack input Bridging line input for high output mics or line level sources Use with our Moiyn 8×2 mixer module in the Sweet Ten Rack for mic or line mixing
• DI Load switch for front panel input 33kohms as in the original Biz or 100kohms for a more open tone
• Discrete signal path
• Over Current Resettable Fused (prevents any module problem from affecting your rack)
• ROHS – Lead Free
