Lehle D.Loop SGoS
The Lehle D.Loop SGoS recommended as the centerpiece of your pedal-board management system, a programmable double looper that takes inactive effects out of the signal path. The loops can be used independently of each other. An adjustable buffer is additionally available in every situation and - because not all effect pedals have a volume controller - can even be used to boost them when necessary. The high-end buffer boost has gain margins of up to 12dB and can also be used seperately!
The jack sockets and internal signal routing are entirely stereo, to permit full-quality use of studio, 19" and stereo effect-pedal units, too. This is assured by the True Bypass characteristics of the Lehle switchers and their gold-plated-contact relays. The signal ground is also switched, to eliminate hum in your effect loops, and a pop-and-click suppression circuit avoids annoying switching noise.
Programming is as easy and as intuitive as you would expect from Lehle products, whether via remote, using MIDI program change commands, as a stand-alone unit, or combined with other SGoS switchers. One very popular combination is to use the Lehle D.Loop SGoS with the Lehle Dual SGoS - they can mutually monitor and control each other, and manage effects and amps. And a simple stereo patch cable is all you need to hit just the right tone!
Gold-plated Relays & Switches
The signal from the pickups of an electric guitar or bass is so weak that poor quality cable, cold joints and cheap contact materials ruin your sound. Switch contacts need to be make of special materials to prevent loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolute zero-loss switching.
MIDI Send & Receive
All products in the Second Generation of Switching (SGoS) range are programmable and can be networked with each other via MIDI program-change commands. External MIDI equipment can also be integrated without difficulty. Programming is intuitive, quick and easy to learn - www.lehle.com features a video to help you.
No Hum Loops
Allo Lehle Products not featuring an LTHZ transformer switch the signal ground parallel to the signal itself via switches or relays with gold-plated contacts. Hum loops are thus errectively eliminated when switching backwards and forwards between different signal sources without, simultaneous activation of two amps.
Adjustment of vilume or distortion using a gain controller is a vital feature in many situations. The gain controllers on the corresponding Lehle products feature black anodized aluminum knobs set back into the housing so they can be easily fingertip rotated but maintain their setting during performance and transportaion.
Many effects units feature stereo outputs, OR instruments frequently have two pickup systems, e.g. a combination of conventional magnetic and Piezo types, to emulate an acoustic sound. Lehle accessories are ideal for trouble-free routing of such dual-channel stereo signals. All stereo capable Lehle products are, of course, also suitable for mono operation.
Q: What does SGoS stand for?
A: SGoS stands for Second Generation of Switching. The new series of Lehle switchers features a
TRS socket for connection with other Lehle SGoS switchers and external MIDI equipment for synchronization. SGoS switchers can receive MIDI program change commands and are very easy to program, they can also send MIDI program change commands and function as a MIDI controller.
Q: What is the effect of an impedance converter?
A: The sound will be freshened up and signal loss through long cable runs will be compensated.
Q: What is the benefit of a buffer/impedance converter before my effects chain?
I heard about the SD, but I am uncertain how this works and whether I need this for my pedal board.
A: A high impedance / HiZ signal can be weakened by an increasing number of fx-pedals, even true bypass effects. The difference can be felt by connecting your instrument with a short cable directly to your amplifier and focus on the details in sound and dynamics.
Q: How can I compensate the signal loss on my effects board?
A: By using an impedance converter, which provides a high impedance input socket for the instrument signal and a low impedance output signal that is more resistent against loss.
