MaXiO XD EX8000
1. Introduction
Thank you for choosing the ESI EX8000, part of the MaXiO XD system.
EX8000 is a high performance 24-bit, 192 kHz AD/DA converter that features 8 balanced inputs
with microphone preamps, XLR/TRS combo connectors and 10 step LED metering lights for each
input channel. EX8000 also provides 8 analog output channels, multi-channel AES/EBU and
S/PDIF digital I/O, ADAT I/O and a headphone output for monitoring.
You can use EX8000 either as a very powerful standalone device or in combination with the
MaXiO PCI host card as a high-end multi-channel recording solution for the PC.

2. Description of EX8000
2.1 Front Channel Section
1
Analog Balanced XLR / TRS (Combo) Input Connector
EX8000 provides 8 combo connectors (XLR and 1/4" TRS) on
the front panel that are used as balanced analog inputs for line
level signals and microphone connection (via XLR).
2
Microphone Input Selection Switch
Every input channel can be used for line level or microphone
signals. When this switch is enabled, a microphone can be
connected via XLR. In this case phantom power is supplied
(when enabled, check no. 7). When the switch is not enabled, the
XLR and TRS inputs are used for balanced line level signals.
3
Input Gain Control
Controls the amount gain applied to the input signal from the
XLR or TRS connector of specific channel. Microphone signals
can be amplified with 48dB maximum, line level signals with up
to 30dB.

Analog Input / Output Level Meter
The two level meters indicate the signal level for the analog inputs and outputs. The level meter
on the left shows the input signal; the level meter on the right shows the output signal of the
corresponding channel. A range from 0dB to 60dB in 10 dB-steps is displayed.

Phantom Power Switch
5
6
+48V DC phantom power (for balanced condenser microphones) will be
supplied via every XLR input connector when this button is enabled.
7
Note that this affects only those input channels that are set to receive
microphone signals (check no. 2).
· Before you turn on the phantom power switch, you must make sure to connect your microphones
to the XLR inputs (with balanced cables).
CAUTION
· After you have turned on the phantom power switch, you should not connect or disconnect a
microphone to any of the input connectors.

AC IN
22
EX8000 needs external AC power. It supports 100~240V AC (free voltage). There
is a spare fuse (5X20mm Glass Fuse) below the connector.
2.3 Clock & Control
9
Clock Source Indicator
Displays the current clock source of EX8000:
- Internal: EX8000 uses its internal clock.
- External: EX8000 works with the clock from the Word Clock input.
- Digital In: EX8000 works with the clock supplied from the AES/EBU,
S/PDIF or ADAT input.
- E.D.I: EX8000 works with the clock from the MaXiO PCI host
card.
10
Clock Frequency Indicator
Displays the current sample rate of EX8000.
11
Clock Select Button 1
When EX8000 is working in stand alone mode, you can choose the
clock source with this button (Internal, External, Digital In). This
function is not available when EX8000 is connected to the MaXiO PCI
host card.

Clock Select Button 2
When EX8000 is working in stand alone mode, you can choose the sample rate with this button
(44.1 ~ 192 kHz). This function is not available when EX8000 is connected to the MaXiO PCI
host card.

Word Clock Input
The Word Clock input allows you to synchronize EX8000 with other devices. When
EX8000 is connected to a Word Clock source, EX8000 will synchronize to it.
2.4 Analog Outputs & Inserts
8
Headphone
You can monitor the playback signal from output 1, 2 through the headphone
output. The output level can be adjusted with the pot.
14
Inserts
The inserts allow you to use the microphone preamps of EX8000 for incoming signals, then run
the signal through external hardware effects before the AD-converter processes the signal. In
order to use the inserts, you typically need a so-called "insert-cable"
with a 1/4" TRS connector on one and two 1/4" mono connectors on
the two other ends. Here is a description of the insert connector:
- Tip: return signal (input from effect processor)
- Ring: send (output to effect processor)
- Sleeve: common ground
15
Analog Balanced TRS Output Connectors
EX8000 has 8 balanced/unbalanced analog outputs (-10dBV) with TRS connectors.
16
Analog Balanced XLR Output Connectors
EX8000 has 8 balanced analog outputs (+4dBu) with XLR connectors.
