THE TOTAL PACKAGE

More than a synthesizer, the ARP 2600 is a complete sound design studio. Even today, the ARP 2600 stands as a bridge between the individual elements of modular synthesis and the immediacy of a production / performance instrument. Included are an ample supply of oscillators, envelopes, a filter and amplifier – all of the building blocks of analog synthesis. But the ARP 2600 goes even further, with a spring reverb tank and even a pair of monitor speakers. Also present is much of the versatility of a vintage modular system, including a ring modulation, lag and voltage processors, an envelope follower, audio preamp, a clock-able switch, noise source, a sample & hold module, signal inverters, an auxiliary mixer, and even a set of parallel-wired/multi jacks.

NORMALLED PATHWAYS

Nearly every slider and switch on the ARP 2600 front panels is hard wired to specific control source. For example, the front panel controls allow the pitch of Oscillator 1 to be controlled by the keyboard (On/Off switch), the output of the Sample & Hold module (slider), the shape of the ADSR envelope generator (slider), and/or by the sine wave output of Oscillator 2 (slider), and each in varying amounts. These hardwired pathways provide massive amounts of immediate control that make excellent use of all the ARP 2600 has to offer, allowing the ARP 2600 to be played as is – no patching needed. In true modular fashion, inserting a patch cord into the jack associated with any hardwired control overrides that internal connection, letting you create a new signal path of your choosing. As a programming aid, the detailed panel graphics clearly show the available signal routings.

PATCH BAY PRECISION

Unlike earlier modular synthesizers that relied on bulky 6.3mm (1/4") jacks and patch cords, the ARP 2600 uses a more streamlined 3.5mm (1/8”) jack that allows for more patch points to occupy the same amount of panel space, delivering more options and more versatility. Most of the patch points are arranged in a single row below the controls of the individual sound modules. This arrangement keeps the main panel clear and unobstructed for tweaking the controls during performance. Needless to say, these patchable connections and the onboard processors can be used to interact with nearly any modular or Eurorack synthesizer system.

THE OSCILLATORS

ARP Voltage Controlled Oscillators (VCO) are extremely stable in their tuning. All three oscillators feature Initial Tuning and Fine Tuning sliders, and every oscillator can be designated as an LFO (Low Frequency Oscillator) modulating oscillator or as an audio oscillator. (Additional LFO modulation sources are available on the ARP 3620 keyboard; included.) Each oscillator generates multiple wave shapes at once. Available Waves include Sawtooth, Square, Triangle, Sine, and Pulse. The Pulse wave of Oscillator 2 and Oscillator 3 include a manual Pulse Width control, and Pulse Width Modulation is available on Oscillator 2. One audio oscillator can be used to modulate the frequency of another audio oscillator to create analog FM effects.

THE FILTER

The ARP 2600 is equipped with a 4-pole Voltage Controlled Filter (VCF), offering a roll-off curve of -24dB per Octave. As with the oscillators, the ARP 2600 filter also offers a Fine Tuning slider. The addition of Fine Tuning allows precise and useful control of the pitch of a self-resonating filter. The input mixer stage of the VCF includes sliders for each Oscillator, the Noise Generator, and the output of the Ring Modulator. Over time, the ARP 2600 historically went through a number of changes; some were cosmetic, and some were more crucial to the sound. The Filter Type switch selects between a filter response more closely related to either earlier or later models of the ARP 2600. THE ENVELOPES

Two Envelope Transient Generators (EG) are available on the ARP 2600. The first is a full four-stage Attack, Decay, Sustain, and Release Envelope. The second EG offers variable Attack and Release only. The Manual Start button allows the Envelopes to be retriggered at any time, without using the keyboard. The Envelope module also provides both Gate and Trigger outputs – ideal for patching into another analog modular or Eurorack system.

THE AMPLIFIER

In order to produce and output sound, the ARP 2600 relies on a Voltage Controlled Amplifier (VCA) to bring the output up to a suitable level. The Amplifier features both Linear and Exponential control inputs, and the Initial Gain setting provides continuous output at its highest setting.

OVER AND OUT

Following the VCA, the audio signal of the ARP 2600 passes through the Stereo Mixer section, the internal Spring Reverb tank, and on to the main outputs, the headphone jack, and the internal Left and Right speakers.

PLUG AND PLAY

The ARP 2600 is equipped with two low-impedance XLR outputs (Left and Right) for direct connection to a recording console or sound system – no direct boxes or line-matching transformers are required. A headphone output is also provided. MIDI is transmitted and received via old-school din-style IN, OUT, and THRU jacks, and also via USB. Three foot switch jacks (footswitches sold separately) on the 3620 Keyboard provide hands-free performance control over Portamento (On/Off or Momentary) and the Interval Latch. The front panel offers a Preamp input for processing another audio source.
