Fig. 3.1: Connecting an amplier
Please follow these steps to connect your TRUTHs to a power amp: Loosen the
plus screw (red ring with a “+”) and the minus screw (black ring with a “-”).
Nowinsert the plus cord of the speaker cable connecting the amp to your TRUTH
into the plus opening. Then, connect the minus cable into the minus opening.
Tighten the screws. Do the same to connect the other TRUTH.
◊ Make sure that all connections are done properly. Speaker cables are
color-coded to help avoid confusion. You’ll know that the signal is
inverted (i.e. you’ve mixed up the connections) when you notice that
bass frequencies are getting lost and when the stereo characteristic of
the signal is majorly worse.
◊ Always make sure that bare wire ends never touch the open end of
another speaker cable, speaker connectors or metal parts of your amp.
3.1.1 The truth about speaker cables
Carefully approach the choice of what cables you use. Which cables you use can
have a major inuence on your sound. Cables of various lengths and diameters
aect the resistance value—causing a loss in power.
On the other hand, that doesn’t mean that you should be buying high-end cables
that cost as much as your speakers. Simply use the following rule of thumb:
Whenever possible, use cables with large diameters (gauge) and keep the
cable length to a minimum. The screw clamps on your TRUTH can accept cable
thickness of up to 7 mm (9 AWG).
3.1.2 Amp
The power rating of the amp you use should be roughly twice the load capacity
of your TRUTH. Consequently, the B2030P should be operated with an amp with a
load capacity of 2 x 200 Watts, and the B2031P with an amp with a load capacity
of 2 x 300 Watts.
Also, you should keep in mind the impedance of your TRUTH in order to guarantee
optimal power delivery. The B2031P’s impedance is 4 , whereas the B2030P’s
is 8 . Use an amp whose power rating roughly corresponds to the values
recommended in the table. The impedance should correspond to the values listed
in the table:
TRUTH Amp power rating
B2030P 200 W into 8 Ohm
B2031P 300 W into 4 Ohm
Tab. 3.1: Recommended amp power ratings
Of course, you can use amps with higher power ratings. However, make sure
not to exceed the load capacity of your TRUTH. Damage to speaker components
caused by exceeding their load capacity is not covered by the warranty.
3.1.3 Protecting your TRUTHs
To ensure that your B2030P/B2031P last for years to come, you should denitely
keep the following in mind:
• Always turn the volume down on your amp before switching it on or o
• When powering your equipment up/down, the amp should always be the
last one to be powered up and the rst one to be powered down. This way,
you avoid loud crackling noise that occurs when you turn studio equipment
on or o
• Always make sure your audio signal level is optimally set. Avoid overdriving
your amp
• Do not push your studio monitors beyond their physical limitations.
Eventhough your TRUTH has sucient power overhead, you can still damage
it if you drive it too much or crank the volume all the way up for longer
periods of time
3.2 Speaker placement suggestions
Since the sound of a speaker depends to a great extent from its surroundings,
placing your TRUTH correctly is very important. Please try to follow these
suggestions through. Your eorts will be rewarded with better sound and
higherresolution.
Both speakers are built identically. There is no need to concern yourself with
which speaker should be placed left and which speaker should be placed right.
Place the TRUTHs on a at and stable surface, if possible use a dedicated speaker
stand. In this way, the speaker is acoustically decoupled and won’t induce
vibrations in nearby objects, which would aect the bass response. If you cannot
use a stand, put the TRUTHs on spikes or damping foam material. Another aspect
is the distance between speaker and wall: keep the speaker away from the wall,
as this would emphasize the bass response, particularly in corners, where two
walls form an angle.
