SETTING UP

Unpacking and Inspection

Your QuadraVerb 2 was packed carefully at the factory, and the shipping carton was

designed to protect the unit during shipping. Please retain this container in the highly

unlikely event that you need to return the QuadraVerb 2 for servicing.

The shipping carton should contain the following items:

• This instruction manual

• Alesis QuadraVerb 2 with the same serial number as shown on shipping carton

• AC Power Supply Adapter

• Alesis warranty card

It is important to register your purchase; if you have not already filled out your warranty

card and mailed it back to Alesis, please take the time to do so now.

AC Power Hookup

The QuadraVerb 2 comes with a power adapter suitable for the voltage of the country

it is shipped to (either 110 or 220V, 50 or 60 Hz).

With the QuadraVerb 2 off, plug the small end of the power adapter cord into

QuadraVerb 2’s [POWER] socket and the male (plug) end into a source of AC power.

It’s good practice to not turn the QuadraVerb 2 on until all other cables are hooked up.

Alesis cannot be responsible for problems caused by using the QuadraVerb 2 or any

associated equipment with improper AC wiring.

Line Conditioners and Protectors

Although the QuadraVerb 2 is designed to tolerate typical voltage variations, in

today’s world the voltage coming from the AC line may contain spikes or transients

that can possibly stress your gear and, over time, cause a failure. There are three main

ways to protect against this, listed in ascending order of cost and complexity:

• Line spike/surge protectors. Relatively inexpensive, these are designed to

protect against strong surges and spikes, acting somewhat like fuses in that they

need to be replaced if they’ve been hit by an extremely strong spike.

• Line filters. These generally combine spike/surge protection with filters that

remove some line noise (dimmer hash, transients from other appliances, etc.).

• Uninterruptible power supply (UPS). This is the most sophisticated option. A UPS

provides power even if the AC power line fails completely. Intended for computer

applications, a UPS allows you to complete an orderly shutdown of a computer

system in the event of a power outage, and the isolation it provides from the

power line minimizes all forms of interference—spikes, noise, etc.

Audio Connections

The connections between the QuadraVerb 2 and your studio are your music’s lifeline,

so use only high quality cables. These should be low-capacitance shielded cables

with a stranded (not solid) internal conductor and a low-resistance shield. Although

Chapter 1 - Setting Up quality cables cost more, they do make a difference. Route cables to the QuadraVerb 2 correctly by observing the following precautions: • Do not bundle audio cables with AC power cords. • Avoid running audio cables near sources of electromagnetic interference such as transformers, monitors, computers, etc. • Do not place cables where they can be stepped on.

While still using a mono input, you could connect two cables to the [L] and [R] OUTPUTS of the QuadraVerb 2 to a stereo amplification system or two mixer inputs.

Chapter 1 - Setting Up The QuadraVerb 2 may be connected to a mixing console in several ways. Usually, it is connected to the auxiliary send and return controls of the mixer. Another method of interfacing is to connect the unit directly to the insert send and return patch points of the channel that is to be effected. Still another way of interfacing the QuadraVerb 2 to a mixer or recording console would be in-line across the output of your mixing console.

Setting Up - Chapter 1 J Most Preset Programs route the LR IN signal to the LR OUT.When connecting to a mixer’s aux sends and returns. the Global Direct Signal Mute should be set to ON. To remove all direct routings of inputs to outputs on all Programs simultaneously: ¿ Press [GLOBAL]. The [GLOBAL] LED will be lit. ¡ Press [< PAGE] once. This selects Global Page 9. The display will read: GLOBAL DIRECT SIGNAL MUTE: OFF ¬ Turn the [VALUE/ENTER] knob to the right until the display reads “ON.

Chapter 1 - Setting Up Mono In - Stereo Out. If you only want to feed the QuadraVerb 2 a mono input, but wish to connect both of its outputs back to the mixer, you will need three 1/4" audio cables. Connect a cable from an effect send to the [R] INPUT of the QuadraVerb 2, another cable from the [L] OUTPUT of the QuadraVerb 2 to an effect return or other mixer input, and another cable from the [R] OUTPUT of the QuadraVerb 2 to an adjacent mixer input.

Setting Up - Chapter 1 Usually, insert connections require a special, stereo-splitting Y-cord to be connected (one stereo plug provides both send and return while two mono plugs connect separately to an input and output). These are known as TRS connectors (tip-ringsleeve). The tip of the stereo plug typically carries the send or output of the insert jack, while the ring carries back the return. The sleeve represents a common ground for both signals.

Chapter 1 - Setting Up Stereo. In the case where a stereo instrument, such as a keyboard or sampler, is connected to two separate channels of a mixing console, you will need two 1/4" TRS cables, one for each channel. The connection is made in a similar fashion as described above.

Setting Up - Chapter 1 Tip 2 1 Sleeve 3 Ring Avoiding Ground Loops In today’s studio, where it seems every piece of equipment has its own computer chip inside, there are many opportunities for ground loop problems to occur. These show up as hums, buzzes or sometimes radio reception, and can occur if a piece of equipment “sees” two or more different paths to ground.
