Arcam Logo - Manual (Page 6)

E-6
Stereo system with no LFE
This is a typical two-channel system (such as Arcam’s
Solo). Logo is connected to L/R preamplifier outputs.
The crossover frequency on Logo should be
adjusted to the low frequency roll off of the main
speakers (see the manual for your speakers for this
information). The Q-control (
X-OVER Q ) can be used
to fine-tune the integration of Logo and your main
speakers.
Sub/sat system
This is a surround-sound system (such as Arcam’s
Solo Movie 5.1) where all the main speakers are
satellite speakers, defined as ‘Small’. Logo is connected
to output marked
SUb , SUbWOOFER or LFE .
The LFE input bypasses the crossover in Logo, so the
crossover frequency should be set by the surround
sound amplifier. For the crossover setting, please see
the response of your satellite speakers which may
vary from around 70Hz for large satellites, to 150Hz
for small satellites. We recommend 80Hz as a starting
point if you are unsure.
Sub/full range+sat system
This is a surround-sound system (such as Arcam’s
Solo Movie 5.1) where full range L and R speakers
are combined with satellite (or with full range) rear
speakers. The system should be connected with
both the
SUb , SUbWOOFER or LFE output connected to
IN LFE and Left/Right preamplifier outputs attached to
IN L / IN R on Logo.
In such systems, Logo can be set up to work with two
crossover frequencies. One frequency is set up for the
rear speakers using the surround amplifier crossover,
and one frequency for the full range Left and Right
speakers, using the Logo crossover.
Direct mode in Arcam
surround amplifiers
If you wish to have your system set up to use
the crossover in the surround amplifier for 5.1
or 7.1 material, but use Left and Right full range
speakers with Logo filling in for two-channel
material, you can use Direct mode.
Connect the amplifier and Logo as in the
Sub/full range+sat system diagram. In the
amplifier, set up all speakers to ‘Small’; this
redirects bass to Logo via the LFE channel. To use
the system’s full range, activate ‘Direct mode’ for
two-channel sources. This sends the full range
signals to the Left and Right speakers and use the
IN L / IN R inputs to Logo via its own crossover.
