2. TRS input
– this jack accepts TRS input connections, either balanced or unbalanced. For
balanced connections, a 3-conductor TRS plug is necessary. The TRS input is wired like this:
INPUT SIGNAL
TRS CONNECTIONS
+ Tip
- Ring
Shield Sleeve
Unbalanced wiring works with either a 2- or 3-conductor TRS connector. A 2-conductor TRS plug
(or sometimes also just called TS plug) automatically grounds the minus signal input, whereas a 3-
conductor TRS plug wired unbalanced provides the option of leaving the minus open or grounded.
We recommend that you ground the unused part.
3. vent port
– uniK plus is a vented box speaker system with a vent port on the rear panel. Because
of this, it is better to keep some small distance from the wall and not to put the speaker directly into
a corner of the room (as the two sides of the corner would generate different reflections). One
option to deal with this in case it cannot be avoided or if it is your preference, you can close the vent
port with the included ESI Bass Port Plug
TM
(described in section 3.7) that ships with uniK plus.
4. gain level adjustment
– use this gain control knob to adjust the speaker properly to the input
level from the sound source. Make sure to setup all speakers accordingly. When set to 0 (middle
position), the input level is set to the recommended calibrated level to reach the most optimised
dynamic response on the output (based on a a balanced XLR or TRS signal with +4dBu reference
level).
5. character selection (room adjustment)
– via the character selection it is possible to tilt the
whole frequency spectrum up (
BRIGHT
) or down (
SMOOTH
). This allows you to adjust the sound
according to the requirements in your room as well as to your own hearing preferences and
requirements.
When set to 0 (middle position), the frequency response is optimised, i.e. as linear as possible.
When the value is tilted upwards, the higher frequencies will appear stronger, yet the whole
frequency spectrum will match accordingly. When the value is tilted downwards, the high
frequencies will appear less strong. It is recommended to adjust the
CHARACTER
first, before you
change something on the
LOW
and
HIGH
knobs. Also make sure that each speaker has exactly the
same settings.
6. high frequencies (room adjustment)
– the
HIGH
knob allows you to adjust the high frequencies
via a built-in EQ mostly affecting the area around 10kHz, by around 1dB for each step up or down,
according to local requirements and your taste.
