3 Modes Of Impeccable Sounding Delay (Mode D: Digital Delay, Mode A: Analog Delay, Mode T: Tape Delay) Each of the three modes offers up to 1 second of delay time. From 12 o'clock to zero is 500ms, which has its own characteristics. From 500ms to 1 second of delay time, they are completely different calibers. When selected for a shorter delay time, it is very noticeable and adds a lot of atmosphere and mood. Push it further and you get a rhythmic delay, perfect for strumming and adding that extra atmosphere to your riffs. Each of the three delay modes is unique and distinct, giving you it's own unique flavour when selected. Features Pairs Perfectly With Distortion Silos was meticulously designed to respond well to gain and overdrive saturation. Presets Silos has six available preset slots for you to save and recall your favorite settings. The settings for each of the three controls, the mode switch and the expression jack assignment can be saved and recalled in any of the slots. Easily Switch Between Delay Modes Silos has two operating modes which are extremely easy to switch between on the fly! In Live mode, the pedal will operate exactly where the controls are set and any changes will have no effect on the presets unless saved. In Preset mode, stored presets (including expression pedal mapping) are selected using the Preset switch, and the physical settings of the controls will be ignored. User-Assignable Expression Control Use any TRS expression pedal to take control over the Time, Repeats or Mix. Specifications Product Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs Current Draw: 75 mA Input Impedance: 500 kO Output Impedance: 100 O TRS expression pedal wiring: Tip: Wiper Ring: +3.3V Sleeve: Ground Flexi-Switch® Technology: This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching. For standard latching operation: tap the footswitch once to activate the effect and then tap again to bypass. For momentary operation: hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed. Silos is buffered bypass with tails. Power is required to pass signal. Power: This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
