gain range is 21.5dB to 76dB. In the INP ATTEN mode, the P-SOLO Ribbon is set to a
fixed gain of 12dB. The INP ATTEN mode affects both mic and instrument inputs.
HPF High Pass Filter selector. Use this to reduce undesirable low frequency
background noise. The 80Hz setting is appropriate for many musical and voice
applications. Note that use of the HPF will most likely not eliminate the need for a pop
screen for close-mic’d vocal use.
The INSTRUMENT input (DI) is used for connection of electric instrument pickup or
synthesizers. The DI we’ve designed for the
P-SOLO Ribbon typically exceeds the
sonic performance of acclaimed, dedicated DI products. It provides excellent articulation
and control for electric/acoustic bass, detail and smoothness for stringed instruments
and keyboards. A microphone plugged into MIC IN will be automatically de-selected
when an instrument is connected to the INSTRUMENT input. Settings for GAIN and
HPF apply to the DI input in the same manner as they apply to mic input. The gain
range for the direct inputs is from -4 dB to +50 dB at normal gain and -14 dB in the INP
ATTEN mode. (See SPECIFICATIONS section for more information.)
NOTE: The INSTRUMENT input is for unbalanced sources only. DO NOT use a TRS
(balanced) plug for this input, as the DI will not function correctly.
Level Indicators. Use these to match signal level between the P-SOLO Ribbon and
devices to which it is connected - and to avoid overloading the preamp.
 SIG indicates that a signal is present on the channel. It illuminates when the signal
level exceeds -24dBu.
 +4 illuminates when the signal reaches normal operating level of +4 dBu.
 OL illuminates when the signal level exceeds +26 dBu, which is 5 dB below the
overload point for the P-SOLO Ribbon *.
 Note that the overload level of the P-SOLO Ribbon is +31dBu at the output*. This
level exceeds the input capability of some devices (check manufacturer’s
specifications). In such cases it is appropriate to use the intermediate level indicators
(+4, +12) to set the maximum output level of the
P-SOLO Ribbon to match the
maximum input capability of the connected device. In other words, it is possible to
cause overload distortion in the connected device even though the
P-SOLO Ribbon
level indicator does not show a red light.
* Maximum output level in the INP ATTEN mode is +27dBu.
