Product info

  • Product Name: ExaktBox Sub


  • Date of Introduction: September 2015
  • Type: Exakt Digital Crossover with DAC designed for use with subwoofers
Configurable for one or two subwoofers
Software upgradable to support more and more subwoofers
Connects to internal subwoofer power amplifiers
  • Can only be used with Exakt-Link output products AND Exakt speakers/Exaktbox

Support

Linn Support Site


Installation

If you desire to locate the ExaktBox Sub with your subwoofer rather than your main equipment stand, we advise using suction cups. This will allow safe, damage-free fixing of the Exaktbox-Sub to subwoofer cabinets. Not for mounting on a wall or ceiling.

Configuration

Manage Systems

Using Manage Systems to configure Exaktbox-Sub


1. In the GENERAL tab select the :

DEVICES
EXAKTBOX            Exaktbox Sub >


2. Select SPEAKERS CHANGE CONFIGURATION

3 This will open a entry box with three configurations

CHANNEL
MONO:
To configure for single channel Subwoofer. This will extract the Bass audio from the front left and right channels. This is primarily for use in Stereo music playback. It does NOT use the LFE channel in Surround Sound playback.
LFE SUBWOOFER
To configure for single channel LFE playback. This ONLY works with Surround Sound media. There is NO output on Stereo playback
LEFT SUBWOOFER + RIGHT SUBWOOFER
Use this option if you have two subwoofers connected use this setting
MANUFACTURER
Declare the Sub-woofer Manfacture. (You cannot have two different Subwoofers configured for the Exaktbox-Sub. They must both be the same make and model)
MODEL:.
Declare the Sub-woofer Model. (You cannot have two different Subwoofers configured for the Exaktbox-Sub. They must both be the same make and model)

Back Panel Connections

Linn-Exaktbox-Sub-rear-Connections.jpg


  1. MAINS INPUT - To connect to the mains electricity supply.
  2. EXAKT LINK - To connect to Exakt compatible devices (Exaktbox, Exakt Speakers, Urika II etc)
  3. ANALOGUE OUTPUTS (XLR,variable level) - To connect to power amplifiers with balanced (XLR) analogue inputs. (300ohm Output impedance)
  4. ANALOGUE OUTPUTS (RCA, variable level) - To connect to power amplifier with unbalanced (RCA) analogue inputs. (300ohm Output impedance)
  5. FALLBACK - To put the device into Fallback mode (used when reprogramming)


Note: Both XLR and RCA outputs are active simulatneously.

EXAKT LINK Connections

Example if you are using a Klimaxe DSM/1, Akudoriks and Exaktbox sub:

ExaktSub links.jpg


The Exakt-link cable can supply digital audio for multiple speakers.
Use Manage Systems setup pages to declare if Channel1 is left or right hand channel, Channel2 is left or right hand channel and the type/quantity of subwoofers to the Exaktbox sub.

Installation

Please read the following carefully before installing the unit in your system – your unit may need to be reconfigured by your Linn retailer.

  • The ExaktBox is shipped from Linn with no speaker setup and must be configured with Manage Systems software.

Operation

The Exaktbox Sub can only be used in conjunction with Exakt speakers or Exaktboxes with two channel audio
You cannot mix the Exaktbox-Sub with the left/right speakers being fed from the Linn DS/DSM analogue sockets. Manage Systems will allow you to set this up but no audio will fed to the ExaktBox-sub

If you try and connect up the Exaktbox sub with non-Exakt speakers, Manage Systems will enable Space Optimisation+ and only list the Exakt products, it will NOT list any passive speakers. This means that you cannot setup the room for Space optimisation as only the Exaktbox sub can be setup.

Setup the Exaktbox Sub in the same manner as an Akurate Exaktbox, select the Speaker (or sub-woofer in this case), enter the serial number and which channel to process -left, right or Mono. (If you are using two sub-woofers define one as left and one as right or both as mono. If you are only using one subwoofer select Mono)

Linn Subwoofers

  • Sizmik (1025 & 1045), Majik 126, Akurate 226, Akurate 221, Klimax 345
  • Connection: Connect left, right or both RCA outputs from the Exaktbox sub to the appropriate RCA inputs on the subwoofer.
  • Set the subwoofer parameters as indicated below:

Parameter

Exakt options

Exakt usage can be found in Klimax_Exakt_System

One of the beneifts of the Exakt system is that you can easily setup and optimise your listening environment. Simply open Manage Systems webpage and follow the Space_Optimsation+ & Space Optimisation+ (Advanced)



Supported Subwoofers

Examples using one ExaktBox Sub

  • Afekt (1off or 2off)
  • Akurate 226 (1off or 2off)
  • Akurate 221 (1off or 2off)
  • AV5150 (1off or 2off)
  • Klimax 345 (1off or 2off)
  • Majik 126 (1off or 2off)
  • Melodik (1off or 2off)
  • Sizmik (1025 & 1045) (1off or 2off)


Non-Linn Subwoofers

Examples using one ExaktBox Sub

  • B&W DB1
  • REL Gibraltar G2, S2, S3 & S5

If you want to use another type of subwoofer, select the Linn Akurate 221 or 226 and put in serial number 1234567. This will select a generic subwoofer profile with settings that can be used with non-Linn Subwoofers.
